The purpose of this activity is for students to revisit Stage 4 of the Number Puzzles center which was first introduced in grade 1. Students work together to use digit cards to make addition and subtraction equations within 100 with composing and decomposing true. Each digit (0–9) can only be used once in a puzzle. Puzzles with less than ten spaces will have leftover cards. 

• Display a gameboard.
• “Which equation can you fill in first?”

The purpose of this activity is for students to choose from activities that focus on addition and subtraction within 100 or story problems. Students choose from previously introduced stages of these centers:

• Number Puzzles
• Math Stories

• “What did you like about the activity you worked on today?”
