This kit has 7 sets of multiplication word problems with matching picture cards that model how to work out the problem. For every multiplication set, there is a set of division word problem and picture cards using the same numbers. For example, there is a multiplication word problem calling to multiply 6 x 3 AND a division word problem card that calls for you to divide 6 by 3. The main purpose of this exercise is to get students to THINK about the work and how the word problem gets worked out, rather than just rote memorization of the facts.
After students match up each word problem with the correct picture card showing how the problem gets worked out, they must write their answers on the activity sheet. There is also a challenge sheet asking students which cards match AND to write a number sentence describing the matching cards.
• CCSS.Math.Content.3.OA.A.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.
• CCSS.Math.Content.3.OA.A.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.
• CCSS.Math.Content.3.OA.A.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
• CCSS.Math.Content.3.OA.A.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 = ?
