Module 1: Properties of multiplication and division and solving word problems with units of 2-5 and 10
Students will be able to:
|
- Demonstrate the commutativity of multiplication, and practice related facts by skip-counting objects in array models
- Find related multiplication facts by adding and subtracting equal groups in array mdels
- Model the distributive property with arrays to decompose units as a strategy to multiply
- Model division as the unknown factor in multiplication using arrays and tape diagrams
- Interpret the quotient as the number of groups or the number of objects in each group using units of 2
- Interpret the quotient as the number of groups or the number of objects in each group using units of 3
- Skip-count objects in models to build fluency with multiplication facts using units of 4
- Relate arrays to tape diagrams to model the commutative property of multiplication
- Use the distributive property as a strategy to find related multiplication facts
- Model the relationship between multiplication and division
- Apply the distributive property to decompose units
- Solve two-step word problems involving multiplication and division, and assess the reasonableness of answers
- Solve two-step word problems involving all four operations, and assess the reasonableness of answers
