3 Oa B 5 3 Oa B 6 3 Oa C 7 о Represent and solve problems involving multiplication and division. 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. 3.oa.a.1 represent and solve problems involving multiplication and division. interpret products of whole numbers, e.g., interpret 5x7 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 5x7. i can multiply to find the product.
3 Oa B 5 3 Oa B 6 3 Oa C 7 о Ccss.math.content.3.oa.b.5 apply properties of operations as strategies to multiply and divide. 2 examples: if 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (associative property of multiplication.). 3.oa.b.5. apply properties of operations as strategies to multiply and divide. students need not use formal terms for these properties. examples: if $6 \times 4 = 24$ is known, then $4 \times 6 = 24$ is also known. 3.oa.c.7 fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 x 5 = 40, one knows 40 5 = 8) or properties of operations. by the end of grade 3, know from memory all products of two one digit numbers. division. speed math. Express the area of each part as a unit fraction of the whole. identify equal parts (3 dd.1) make halves, thirds, and fourths (3 dd.2) make sixths and eighths (3 dd.3) make halves, thirds, fourths, sixths, and eighths (3 dd.4) match unit fractions to models (3 dd.10) ixl's dynamic math practice skills offer comprehensive coverage of common core.
