Challenge your students’ thinking and stretch their number sense with these Switching Addends Number Talk Task Cards—perfect for math enrichment in the second half of the year. These brain teaser-style prompts push students to reason flexibly with numbers as they explore how switching one or more addends can create equal sums across two equations.
Ideal for whole-group number talks, math centers, or small-group problem solving, these tasks encourage deep thinking about addition, subtraction, missing addends, and the commutative property, all within sums to 20. While designed to be rigorous, the reward is in the light bulb moments as students begin to discover patterns, test strategies, and explain their reasoning.
What’s Included:
These tasks are ideal for Quarter 3 or 4 when students are ready for higher-level thinking and open-ended problem solving. Build meaningful math conversations and develop flexible thinking with this engaging and challenging resource.
Looking to build number sense all year long?
This resource is part of the 1st Grade Number Talks Bundle—a complete collection of mental math task cards designed to spark daily math conversations and develop flexible thinking from August to May.
