SALTA 3rd grade

Strand: Operations and Algebraic Thinking Third grade students represent and solve problems involving multiplication and division within 100. 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. a. Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations. (For example, knowing that 8 x 5 = 40, one knows 40 ÷ 5 = 8). By the end of Grade 3, know from memory all products of two one-digit numbers. Standard 3.OA.9 Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends. Standard 3.OA.7 Fluently multiply and divide.

Complete each sentence. I know 7 x 8 = 56, therefore I know ______ divided by 7 = 8. I know 4 x 9 = 36, therefore I know 36 divided by 9 = ______ . I know 3 x 5 = 15, therefore I know 6 x 5 = _______ .

There are 5 tables in the lunchroom. Six students sit at each table. How many students are in the lunchroom?

Mari has 48 crayons. She knows that 8 crayons can fit in a box. How many boxes will she need? Justify your answers with pictures or words. (DOK 3) Observe the multiplication table and tell one pattern you see. Justify your answer by explaining why the pattern is happening and if it will continue forever. Do you see that pattern anywhere else on the chart?
