Multiplication Strategies - Equal Groups
1 Anticipatory Set/Hook
Access the teacher-created Popplet for the week here using an iPad connected to the SmartBoard.
Begin by explaining that today we will be looking at one of the strategies for solving multiplication problems. Today's focus will be equal groups.
Navigate the Popplet to the section titled "equal groups". Review the bullet points attached to that title.
- Direct Instruction:
- On the SmartBoard model how to use the Drawing Pad App to draw equal groups to solve a multiplication problem.
- Model for students how use the Drawing Pad App. Students will need to open the app and select a pencil to draw with. Explain that they may choose different drawing tools throughout the lesson.
- Guided Practice:
- Present a multiplication problem to the students on the SmartBoard and have the students draw equal groups along with you using their iPads and the Drawing Pad App. Repeat this as many times as necessary to ensure student understanding.
- The students will work together with a partner to complete the workbook page associated with today's lesson. The students will continue to utilize the Drawing Pad App to help them solve the multiplication problems.
- As students finish, they will independently play the Farm Factor App. This will allow them even more practice of solving multiplication problems using equal groups. The students will select the app from the home screen and follow the instructions to get started.
- Have students return to their seats to review the concept of equal groups.
- Utilize the Plickers App. Review the process of turning their answer card to show the correct answer and how to check to make sure the teacher got your answer.
- Using the teacher-created test, have the students complete the questions by drawing out their answers on the Drawing Pad App and then showing the correct answer using their Plickers card.

Operations And Algebraic Thinking
|2.OA: Work With Equal Groups Of Objects To Gain Foundations For Multiplication.|
|2.OA.3||Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.|
|2.OA.4||Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.|
|3.OA: Represent And Solve Problems Involving Multiplication And Division.|
|3.OA.1||Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.|
|3.OA.2||Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.|
|3.OA.3||Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.1|
|3.OA.4||Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = � ÷ 3, 6 × 6 = ?.|
