Students will be able to
- draw bar models to solve multistep addition and subtraction problems,
- identify the correct operations to use to solve a problem,
- understand that there may be more than one set of calculations to solve a problem,
- write stories to match a given bar model.
Prerequisites
Students should already be familiar with
- adding and subtracting numbers up to 10,000.
Exclusions
Students will not cover
- numbers over 10,000.
