By the end of this unit students will be able to:
Interpret multiplication in terms of equal groups by drawing arrays or equal groups and writing number stories.
Use the turn around rule (commutative property) as a strategy to solve problems.
Fluently multiply using strategies for all products of 1-digit numbers times 1, 2, 5, and 10.
Represent and solve 2-step number stories involving addition and subtraction and assess the reasonableness of answers using estimation, including rounding.
Add and subtract within 1000 using partial sum addition, counting up, expand and trade subtraction, and other strategies.
Represent a data set with several categories on a given scaled bar graph and use the information presented in the graph to solve one step "how many more" and "how many less" problems.
