Countdown to the Connecticut Mastery Test (Math Component) Larry Hillman, Presenter January 19, 2011 Slide 2 What is the Math CMT? The Fourth Generation of the Math CMT assesses student performance on a range of skills and concepts expected to be mastered by students at each grade level. The skills and concepts are aligned with the content and performance standards in Connecticuts Mathematics Curriculum Framework. Slide 3 The framework includes mathematics content and instructional processes recommended by the National Council of Teachers of Mathematics (NCTM) and assessed on the National Assessment of Educational Progress (NAEP) Slide 4 What type of questions are on the Math CMT? The Math CMT consists of multiple- choice, open-ended and grid-in questions. Slide 5 How is the Math CMT scored? Each multiple choice question is worth 1 point. Each grid-in question is worth 1 point. A student can earn 0, 1 or 2 points on the open-ended questions. In order to receive 2 points, the student must clearly show his or her work, or explain his or her answer. Slide 6 Multiple-Choice Question Format (Example) Alyssa has to read a book for her social studies class. Last night she read of the book. This morning she read of the book. If she still has 25 pages left to read, how many pages are in the book? A.50 C.125 B.75D.150 Slide 7 What must a student be able to do to answer this determine the correct answer to this question? The student will have to add the fractions, but in order to do so, the fractions must have a common denominator. To find the common denominator, the student will have to find the least common multiple (LCM) of 2 and 3. The LCM of 2 and 3 is 6. Rewrite the fractions using the common denominator of 6 (3/6 + 2/6). Add the fractions:3/6 + 2/6 = 5/6 If Alyssa read 5/6 of the book, that means there remains 1/6 of the book left to read. The question tells us that there are 25 pages left to read, so 25 pages = 1/6 of the book. Slide 8 The question being asked is How many pages are in the book? If 1/6 of the book is 25 pages, to find the total number of pages, multiply 25 x 6 = 150 The correct answer is D. 150. Slide 9 Open-Ended Question Format (Example) These numbers form a pattern. 100, 99, 97, 94, 90, 85, 79, 72, ____ Which number should come next in this pattern?______ Explain how you arrived at your answer__________________________________ ___________________________________________________________________ Slide 10 What must a student be able to do to answer this determine the correct answer to this question? The student must be able to identify the pattern presented by the sequence of numbers, and then extend the pattern. Identifying the pattern: What is happening from one number to the next? 100, 99, 97, 94, 90, 85, 79, 72, ____ Extending the pattern: If the pattern continues, what will be the next number? Slide 11 64 Show your work or explain how you determined your answer. (Sample answer): Subtract 1 from the first number to get the 2 nd number; Subtract 2 from the second number to get the 3 rd number; Subtract 3 from the third number to get the 4 th number, etc. Since 72 is the 8 th number in the sequence, subtract 8 from 72 to get the next number, 64. Slide 12 Grid-In Question Format (Example) A Blu-Ray DVD player has a regular price of $245.00. It goes on sale at a 20% discount. What is the sale price of the player? Slide 13 There are two ways to find the correct answer to this question. A student can calculate 20% of $245.00, then subtract that amount from $245.00 in order to obtain the sale price. -or- A student can subtract 20% from 100% (leaving 80%), then calculate 80% of $245.00. Slide 14 Using either method, the student should find the correct answer, $196.00. This answer must be entered into a bubble grid like the one shown below. Slide 15 There are two parts to the bubble grid: *The boxes for students to write the numbers *The bubbles to be filled in Slide 16 Students are encouraged to use this four-step problem-solving method: 1. Identify the problem What is the question? What am I being asked to find? What do I know? What information am I given? 2. Create a Plan How do I use what I know to find what I am being asked to find? 3. Follow the Plan 4. Check the Answer Did I answer the question being asked? Does my answer make sense? Is my answer reasonable? Slide 17 Some Problem-Solving Strategies A.Make an organized list B.Look for a pattern C.Make a chart or a graph D.Draw a picture or a diagram E.Guess and check F.Work backward. Slide 18 More Problem-Solving Strategies G.Write a formula or equation H.Use logical thinking I.Make a model J.Make a simpler problem by breaking the problem down into small steps K.Recognize when you have too much or too little information Slide 19 The problem solving strategy that should be used in a given situation is the one that works best for that particular student. Slide 20 Logical Thinking Problem Four musicians, John, Paul, George, and Ringo, are standing in line, one behind the other. John is not third in line. Paul is immediately behind George. Ringo is second in line. In what order are the four musicians standing? Slide 21 What must a student be able to do to answer this determine the correct answer to this question? One strategy might be to make a table and record the information in the problem onto the table. Slide 22 JohnPaulGeorgeRingo 1 2 3 4 Slide 23 The problem tells us that Ringo is second and John is not third. We can enter that information into the table JohnPaulGeorgeRingo 1 2yes 3no 4 Slide 24 Since Ringo is second, he cant be first, third or fourth, so we can eliminate those possibilities. Additionally, nobody else can be second. JohnPaulGeorgeRingo 1no 2 yes 3no 4 Slide 25 Since Paul is immediately behind George, there needs to be two consecutive open spaces. The only options are third and fourth. By process of elimination, John has to be first. JohnPaulGeorgeRingo 1yesno 2 yes 3no yesno 4 yesno Slide 26 Solution 1 st John 2 nd Ringo 3 rd George 4 th Paul Slide 27 What skills are tested on the Math CMT? The Math CMT is broken down into 25 discrete topics known as strands. Each strand is meant to assess student performance on specific skills. These Strands include: Identifying place value Fractions, decimals and percents Computation using whole numbers and decimals Solving word problems Slide 28 Estimating Solutions to Problems Customary and Metric Measures Geometric Shapes and Properties Tables, Graphs and Charts Probability Patterns Algebraic Concepts Logical Reasoning Slide 29 How is the Math CMT administered? The Math CMT is broken into 3 sections, taken on 3 separate days. On one section, the students are not permitted to use calculators. On the other two sections, calculators are permitted. Slide 30 Will my child be ready for the CMT? Throughout the school year, your childs math teacher has be helping your child master the skills and concepts that will be tested on the CMT. Our teachers will spend extra time helping students practice those skills in which prior test results have demonstrated the greatest need for improvement. Slide 31 What has the staff at West Rocks Middle School been doing to help my child prepare for the Math CMT? Administering CMT Progress Tests; Tracking student performance on the Progress Tests in order to identify those skills for which the teacher needs to devote additional instructional time; Slide 32 Introducing students to Study Island, an online resource where students can answer CMT-type questions on their own and receive immediate feedback Conducting after-school extra-help sessions to improve student performance on selected strands. Slide 33 Slide 34 Is there anything I can do to help my child prepare for the CMT? Slide 35 Of course!!! You can help your child prepare for the Math CMT in several ways: Slide 36 Have you child memorize the multiplication table Slide 37 Quiz your child on the meaning of math vocabulary terms Slide 38 Examples of CMT math vocabulary: What is a numerator? What is a factor? What operation do I do to find the product of 2 numbers? What is a pattern? What is the place value of a number? ( A complete vocabulary list will be given to you tonight) Slide 39 Have your child go online and practice with Study Island Slide 40 Ask your child to show you his or her homework Your child should routinely have math homework right until the CMT. Continue to be involved! Have your child explain the homework to you. Slide 41 All of the teachers and staff at West Rocks Middle School have the highest expectations of our students on the upcoming CMT. GOOD LUCK!!!
