CCSS Major Emphasis Clusters Operations and Algebraic Thinking

Use the four operations with whole numbers to solve problems.

Number and Operations in Base Ten Generalize place value understanding for multi-digit whole numbers. Use place value understanding and properties of operations to perform multi-digit arithmetic.

Number and Operations – Fractions Extend understanding of fraction equivalence and ordering. Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers. Understand decimal notation for fractions, and compare decimal fractions.

Rationale for Module Sequence in Grade 4 Module 1 begins with a study of large numbers. Students are familiar with big units. For example, movies take about a gigabyte (1,000,000,000 bytes) to store on a computer while songs take about a megabyte (1,000,000 bytes). Place-value concepts are reviewed and extended to the ten thousands place. Students will compare numbers large numbers up to 100,000 and stating which number is greater or less. Students will be able to order a given set of numbers and identify patterns and relationships within patterns of numbers. Students will state a rule for number patterns and find missing numbers in the pattern.

Estimation is a critically important skill for students to quickly and accurately assess the reasonableness of their answers. Students will learn various methods of estimating in Module 2. Students will be introduced to factors, multiples, least common multiples, and greatest common factor. Students will make lists of factors to find the LCM and GCF. They are introduced to “double division” method by successively dividing two numbers by any common divisor. This will also help them to determine the LCM and GCF of two numbers.

In earlier grades, students learned their multiplication facts up to 10x10. In Module 2, students will extend their knowledge to multiplying and dividing multi-digit numbers. The place-value concept is used to facilitate understanding of multiplying with and without regrouping. Students will be able to multiply and divide in vertical form by the end of the module. Students should be comfortable with using the Commutative Property of Multiplication. Teachers should encourage the use of precise vocabulary in this chapter and review terms such as product, quotient, divisor and remainder. Students will apply their work in all four operations to solve real-world problems.

In primary grades, students learned to construct and analyze frequency tables, picture graphs, bar graphs, and line plots. They also used four operations to solve problems based on their graphs. In Module 4, students will continue this work by collecting and organizing data and interpreting line graphs and tables. Students will compare, analyze and classify data as they look for patterns and trends in the graphs.

East Saint Louis District 189 Math Curriculum Grade 4

Students are introduced to line graphs which have two numerical axes. Students will recognize that data flows continuously from left to right in preparation for their work with functions in middle school grades.

Students will use a variety of tools in Module 5 to analyze data, such as average, median and probability. Vocabulary will play a key role in helping students learn the new topics introduced throughout this module. Students will apply their understanding of place value and graphs to develop and use stem-and-leaf plots to find mean, median, mode and range. Students will learn to describe the possibility of the occurrence of different outcomes as a fraction. They will be given opportunities to solve real-world problems to check their understanding and ability to make projections based on the data they are given using different data representations.

In earlier grades, students learned to find equivalent fractions. In Module 6, students will learn how to add and subtract like and unlike fractions with and without renaming. They will be introduced to the concept of fractions of a set and will learn to apply this to real-world problems. Concrete materials are used extensively to illustrate the addition and subtraction of fractions. Students will learn correct vocabulary such as numerator and denominator to refer to their work with fractions. Students will learn to convert from improper fractions to mixed numbers and vice versa. Students will apply their knowledge of finding common factors and multiples to add and subtract unlike but related fractions. Bar models will be used to illustrate adding and subtracting real-world problems to help students visualize the problems they are solving.

In Module 7, students will learn to recognize, compare and round decimals in tenths and hundredths with the use of a number line. Students will be introduced to the meaning and concept of a decimal point and that the digits to the right represent fractional parts of a whole. Students will apply their knowledge of equivalent fractions to decimals through models and number lines. Students will develop an understanding of the rule to describe a sequence of decimals and complete sequences by studying number patterns.

Students will add and subtract decimals up to two places in Module 8. They will learn that the same algorithms for adding and subtracting whole numbers can be applied to decimal numbers. Students will review place value concepts of decimals to aid in working with regrouping in addition and subtraction of decimals. Bar models are a good way to translate the words in a problem into a visual picture from which students can decide what strategy to adopt to solve that problem. Students will extend that skill to drawing bar models for real-world problems with two-step decimal problems.

Students learn that angles can be seen everywhere around them. In Grade 3, students estimated the size of angles by comparing them to right angles. In Module 9, students learn how to estimate angle measures and measure angles with a protractor. They will learn to draw angles up to 180° using a protractor. Another important concept is turns and their relation to angle measure. Students will use the work from Grade 3 (congruence, slides, flips and turns) to relate right angles to fractions of a turn. In Module 10, students extend their knowledge of line segments and continue to explore parallel and perpendicular line segments. Students will learn to use a protractor or drawing triangle to draw perpendicular line segments when a grid is not provided. Students will also learn how to draw parallel line segments using a drawing triangle. Students will identify horizontal and vertical lines.

East Saint Louis District 189 Math Curriculum Grade 4

Students will learn the properties of squares and rectangles in Module 11. They will identify and define squares and rectangles based on their knowledge of angles and perpendicular and parallel line segments. Students will also learn to decompose shapes made up of square and rectangles. Students will learn to find the measures of adjacent angels of a right angle in a square or rectangle. They will also learn to find the side lengths of composite figures by using the properties of a square and rectangle.

In earlier grades, students learned to count grid squares to find the area of a figure. This is extended in Module 12 to find the area of a rectangle by using the formula. Students connect this model to the area model for multiplication. Students have previously learned to add the lengths of all the sides of a figure to find its perimeter. Students will apply what they have learned to find the perimeter of composite figures. They will also learn to find one side of a rectangle or square when given its perimeter or area. Students will be required to apply their knowledge of area and perimeter to solve real-world problems.

In Module 13, students learn to identify lines of symmetry of figures and to make symmetric shapes and patterns. This is a continuation of previous chapters on drawing, analyzing, comparing and classifying two-dimensional shapes based on attributes and properties. Students will solve problems involving congruence and symmetry. Students should be given many opportunities to experiment with making their own symmetrical shapes and identifying the line of symmetry. Students also learn to identify figures with rotational symmetry through hands-on activities.

Module 14 can be done if there is time. This is not a major focus of the Common Core Standards. Two days will be used for assessment for end of year. Those items on the assessment can be ignored or whited out.

Multiplication as scaling is the big idea (not repeated addition). A key strategy is to make estimates for the problems first to build number sense before beginning any paper/pencil computation. Round to compatible numbers (related facts) or largest place value for students. Compatible numbers are especially important during the division section. Use the place value disks to begin all the operations. Keep working on number talks – multiplication and division with multiplication strings and one digit by 2 digit numbers.

Use this principle to recognize and generate equivalent fractions.

4.NF.A.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

Build fractions from unit fractions.4.NF.B.3a Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

4.NF.B.3b Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.

4.NF.B.3c Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations

Numerator, Denominator,Equivalent fraction,Unlike fraction,Mixed number,Simplest form,Improper fractionFraction bar,Division rule,Multiplication rule

Understanding fractions as a number is very important, not just as a part to a whole. Fraction is number of parts out of a total number of equal parts. Denominator represents ordinal numbers. Fractions are numbers, represent quantity amounts, can be shown on a number line, and can be used to perform operations. Estimation of fraction operations is important. Rely on the benchmark fractions students should master, 0, 1, ½, ¼, ¾.To reinforce that the fractions need like denominators, write addition of fractions as

16+ 26=1+26

=36

Simplifying the fractions can be done, but credit should be given if they have the appropriate fraction. Equivalent fractions are created by multiplying or dividing

and the relationship between addition and subtraction.

4.NF.B.4a Understand a fraction a/b as a multiple of 1/b. For example, use a visual fraction model to represent 5/4 as the product 5 × (1/4), recording the conclusion by the equation 5/4 = 5 × (1/4).

4.NF.B.4b Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. (In general, n × (a/b) = (n × a)/b.)

4.NF.B.4c Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. For example, if each person at a party will eat 3/8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?

Solve problems involving measurement and conversion of measurements.4.MD.A.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...

4.MD.A.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit.

by another representation of 1. Remember to compose and decompose fractions just as you whole numbers, and using the fraction strips.Remember, in comparing fractions, a strategy can be to convert to the same numerator to help, i.e. 2/5 and 1/3. You can create an equivalent fraction for 1/3 which is 2/6. So you have 2/5 and 2/6. Which is bigger? Have students focus on the size of the unit fraction. Which is bigger 1/5 or 1/6?The standards give good examples of fraction operations.

4.NBT.A.2 Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

Extend understanding of fraction equivalence and ordering. 4.NF.A.1 Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Build fractions from unit fractions.4.NF.B.3a Understand addition and subtraction of fractions as joining and separating parts referring to the

zero,More than,Less than,Greater than,Least, Greatest,Order, Round,Equivalent fraction

How many tenths are there in 0.4?How many tenths are there in 1?How many tenths are there in 1.4?How many tenths are there in 4?What is the decimal number for 42 tenths?Do the same types of questions as you move to hundredths.Continue with number talks with decimals and key on the students’ familiarity with money. Have students break up numbers into the different place values and write it in different representations. As,

4.6; 4 610 ; 4.60; 4

60100 .

Remember that the same strategies we used to make 100 will be used with decimals to make 1.

Understand decimal notation for fractions, and compare decimal fractions. 4.NF.C.5 Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.2 For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.

4.NF.C.6 Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.

4.NF.C.7 Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.

Generate and analyze patterns. 4.OA.C.5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.

classify shapes by properties of their lines and angles. 4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Geometric measurement: understand concepts of angle and measure angles. 4.MD.C.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

4.MD.C.5a An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.

4.MD.C.5b An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

4.MD.C.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

4.MD.C.7 Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an

Protractor,Degrees,Inner scale,Outer scale,Acute angle,Obtuse angle,Straight angle,Turn,Additive

You may need to play some vocabulary games each day, as riddles, guess my word, word wall categories, etc. The circle is a very important concept – having 360 degrees. The Babylonians may have decided on 360 since there was 360 days in their year. 360 is easily divisible by many factors which makes it easy to work with.Students should be able to measure to the nearest degree. Always have them look at an angle to estimate first, knowing it is obtuse, acute, right, etc.
