1
1

A teacher-facilitated introduction to two-step problems (addition and subtraction only) where students learn to identify the “hidden” question.

Students discover that two-step problems have a hidden question that must be answered first before the problem can be solved. Then they rewrite problems with two questions into a typical two-step problem format and solve two-step problems.

8 problems and a journal question.

Use in small groups, during guided math, during tutoring or intervention, and with the whole class.

This activity includes clear and concise teacher directions, a recording sheet, and conversation starters that give students what they need to have meaningful academic discussions.
