Getting to know the number patterns and relationships math lesson

This lesson engages students to:

• Identify number pairs that add up to landmark numbers (10, 20, 50, etc.)
• Identify and use number patterns and relationships
• Practice computational strategies supporting the development of fluency

Getting to know the manipulative

The match-n-make board provides pairs of numbers that add up to a landmark number. The numbers can be restricted (for example, by only using a landmark of 10, or multiples of 10) to focus on specific strategies and scaffold student learning.

Professional development ideas

• Use lessons as a quick activity to work on fluency with addition.
• Before identifying any pairs on the screen, ask students to write down as many pairs as possible in their math journal, on scratch paper, or individual white boards.
• Divide students into partners or teams to identify pairs. Other teams/partners can indicate agreement or disagreement using hand signals.
• Invite a student to choose one number. Invite a different student to identify the match.
• Ask students to share their strategies for finding matches. Are there any patterns that can help students identify more matches?
• Keep track of the pairs on an interactive board, white board or chart paper as they are found. After the board is cleared, ask students to think of additional pairs.
• Use match-n-make as a mini-lesson or short math activity before or after major transitions (lunch, recess, specialist classes, etc.)
