problem_activity: Stage 2: Subtract within 10
Required Preparation
Materials to Gather
Number cards 0–10
Materials to Copy
Blackline Masters
Check It Off Stage 2 Recording Sheet

Narrative
Students take turns picking two number cards (0–10) to make and find the value of a subtraction expression. Students check off the number that represents the value of the difference (0–10) and then write the subtraction expression on the recording sheet.
Variation:
Students can choose whether to add or subtract after picking two number cards.
