Standard 3.OA.1 Interpret products of whole numbers, such as 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. Standard 3.OA.2 Interpret whole-number quotients of whole numbers. For example, interpret 56 ÷8 as the number of objects in each share when 56 objects are partitioned equally into eight shares (partitive), or as a number of shares when 56 objects are partitioned into equal shares of eight objects each (quotative). Standard 3.OA.3 Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities. For example, use drawings and equations with a symbol for the unknown number to represent the problem.

Write an expression and count the total number of boxes in each array.

Eggs come in cartons with either 2 rows or 3 rows. The carton with 2 rows has 12 eggs and the carton with 3 rows has 18 eggs. If each carton has the same number of eggs in each row, how many eggs are in each row? Use pictures and numbers to justify your answer. (DOK 3) Mia has nine bags with 2 toy animals in each bag. Sara says she has the same number of animals but she only has 6 bags. Could Sara be correct? Use pictures, words, and numbers to justify your answer. (DOK 3)
