Unit 1 – Standard CCSS 3.OA.A.1

Unit 1:Interpret Products of Whole NumbersLEARNING TARGETS• I can identify the total number of objects in a given number of equal groups.

• I can use multiplication to find the products of whole numbers.

• I can interpret an expression such as 5 × 7 as 5 groups of 7.

• I can use pictures, words, numbers, and equations to solve problem situationsrequiring multiplication.

Focus for 9 Traits of Critical Thinking™Adapt: I adjust my actions and strategies to accomplish tasks.

When you adapt, you think flexibly about mathematics. When you adapt, you trydifferent strategies or use a variety of tools to solve problems.

In this unit you will represent multiplication facts in different ways. Why is it goodto know more than one way to represent multiplication?

Examine: I use a variety of methods to explore and to analyze.

When you examine, you use your senses to collect information, organize theinformation, and form conclusions. When you examine, you analyze informationand look for patterns and relationships.

In this unit you will determine which multiplication fact is represented. What canyou examine to determine which fact is represented by a model?

UNIT 1

Pre-AssessmentIn order to inform instruction, the teacher may assign the pre-assessment for the unit. The unit pre-assessment providesteachers with information on student mastery of prerequisite skills to the unit concept. This information will help teachersdetermine concepts that may need review as part of the unit instruction for the whole group and/or for additional instruction withintervention groups. The focus remains on effective instruction of the unit concept.

Focus for 9 Traits of Critical Thinking™The 9 Traits of Critical Thinking include adapt, collaborate, communicate, create, examine, inquire, link, reflect, and strive.These traits foster high-quality thinkers. In each unit of the student edition, two critical thinking traits are selected as focus traits.These traits are identified in the content to reinforce student use in the context of mathematics. The labeling of the focus traitsalso assists students in recognizing specific mathematical tasks, problems, and events in which the application of a focus trait isneeded to complete the activity. The educator should note that each activity in the teacher edition is correlated to traits that areaddressed during student participation. However, implementation of the activities in the student and teacher editions is notlimited to the identified traits since multiple critical thinking traits may be successfully integrated into an instructional plan.

The two focus traits selected for this unit are adapt and examine. Examples of tasks in which students make use of these focustraits are identified and marked with the appropriate icons. It is suggested that the teacher review the following information oneach trait and incorporate the appropriate question prompts into instruction.

Adapt – I adjust my actions and strategies to accomplish tasks.

Engagement indicators for the critical thinking trait adapt include the following.

• Students approach a problem in more than one way.• Students examine options and alternatives to find solutions to a problem.Strategies to facilitate the adapt trait include the following. The teacher—

• guides students to view and solve a problem from new or different perspectives.• designs activities or scenarios that require students to practice flexibility and shift or change their thinking.Questioning prompts to develop the adapt trait include the following.

• What might you do if you review your answer and determine it is not reasonable?• How does ________ help you see this concept from a different perspective?

Examine – I use a variety of methods to explore and to analyze.

Engagement indicators for the critical thinking trait examine include the following.

• Students willingly ask a range of essential questions and employ multiple methods to explore the unknown.• Students reflect on strategies used, self-assess for effectiveness, and determine next steps to produce desired

outcomes.Strategies to facilitate the examine trait include the following. The teacher—

• encourages students to generate and frame thoughtful questions for analyzing a topic (emphasizing quality,not quantity).

• creates opportunities for students to reflect using online boards and debates to challenge assumptions or tooffer different perspectives.

Questioning prompts to develop the examine trait include the following.

• What are some common errors you have observed in ________?• How are ________ and ________ alike? How are they different?

UNIT 1

Concept Exploration 10–15 min

Students work in pairs to complete the Concept Exploration activity on page 2 in the student edition. Afterward, students sharetheir responses with the class. The teacher compiles all the ideas into a class list. The teacher displays real-world examples ofarrays (e.g., desks in rows, date squares on calendars, egg cartons, muffin tins, floor and ceiling tiles, ice cube trays, coincollecting albums). As the teacher displays each real-world array, students outline and shade a replica of the array on centimetergrid paper. Students identify the multiplication fact associated with each array and record it below the shaded grid paper array.Then, in small groups, students brainstorm other examples of arrays in everyday life. Students name the objects, sketchpictures, and write the corresponding multiplication facts.(C.T. Traits: Examine, Inquire, Collaborate, DOK: 2, RBT: Apply)

Formative Assessment 5–10 min

The teacher displays various pictorial representations of multiplication. Some pictures correctly illustrate arrays and others donot. Students record either example or non-example on dry erase boards. Then, the teacher instructs students to draw an arrayto correctly illustrate an example of a given multiplication fact.(C.T. Traits: Examine, Reflect, DOK: 2, RBT: Analyze)

Complete this activity with a partner. Player 1 rolls a number cube marked 2 through 7.That player names something that comes in sets of the number rolled and records it in thebox for the number. For example, if a 4 is rolled, the player might say wheels on a car.The other player then rolls the number cube and states a sentence that gives the totalnumber of things. So, if player 2 rolls 3, that player would state that there are 12 wheelson 3 cars. Play continues until a player cannot think of something to match the numberrolled. The other player wins the game if he or she is the last to be able to name a set ofthings for the number.

Up, Up, and ArrayPlay "Up, Up, and Array" with one or two friends. Each group needs one game board, twodice, and a different color of crayon for each player. Player 1 rolls the dice and colors in anarray showing the product of the two numbers. For example, if player 1 rolls a 3 and a 5,he or she colors 3 rows with 5 in each row and writes the product 15 on the colored array.Player 2 plays and the game continues. A player must pass if there is no room to color anarray for the two numbers rolled. The game is over when all players pass during a round.The player with the most squares colored is the winner.

Extending Student ThinkingThe Math Challenge in the student edition provides opportunities for students to explore and use the math concept to solve non-routine problems. For students in need of additional challenge, an extension activity is provided to enhance learning and toprovide ideas for student investigations.

Activity time is variable

Students independently investigate items that are packaged in multiples (e.g., pens, pencils, tennis balls, kitchen sponges,packages of soda, packages of paper towels). Students may take actual photographs or use a variety of catalogs, newspaper ormagazine advertisements, or online resources to locate pictures. Students create electronic slide shows or posters to illustratethe items they find and present their products to the class.(C.T. Traits: Communicate, Examine, Inquire, DOK: 3, RBT: Create)

Connect to the Student Edition: Math Challenge, page 8

Home ConnectionThe teacher might share the following activities on a class Web page or class newsletter to create learning opportunities forstudents and their families.

• Practice skip counting by 2s, 3s, 4s, 5s, and 10s.• Look at 4 pairs of shoes and show that 4 groups of 2 shoes equal 8 shoes. Challenge your child to find other equal groups of

things, such as flowers in vases, eggs in egg cartons, or apples in bowls.• Discuss the meanings of the words “double” and “triple.”
