This fun, hands-on lesson uses the book 100 Hungry Ants by Elinor J. Pinczes to teach students to use arrays to solve multiplication and division equations.

Students will use models to create arrays to match the story

*This would be a great lesson for a sub to teach/reinforce arrays
* Could be used for the 100th Day
* Reinforce division and multiplication using arrays

Students will be able to…

•Partition a whole number into equal shares using arrays.
•Partition a whole number into equal shares using equal groups.
•Find the product using objects in groups.
•Describe a situation in which a number of groups can be expressed using division.
•Determine the unknown number to make a division equation true.

* Book NOT included
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 = ?.
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.
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.
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.
