What you'll learn
- Identify the problem situation type (adding to, taking from, putting together, taking apart, or comparing) in a one-step word problem
- Solve one-step addition and subtraction word problems within 100 with the unknown in the result position
- Solve one-step word problems within 100 with the unknown in the change or start position, writing an equation with a symbol (such as a box or question mark) for the unknown
- Represent any word problem with a labeled drawing (such as a tape diagram or number bond) and a matching equation
- Solve comparison word problems involving "more than" and "fewer than" within 100
- Solve two-step word problems within 100, writing a separate equation for each step with a symbol for each unknown
