Relate addition and subtraction facts using part-whole relationships!
Number bonds help students develop fluency with related addition and subtraction facts by modeling part–whole relationships and supporting the commutative property.
They provide a concrete-pictorial way to visualize relationships. Students don’t just memorize facts; they see how numbers can be broken down and recombined, making addition and subtraction more intuitive.
Help students practice fluency with this high-quality set of dry erase cards. With number bonds, children develop fact fluency and can see the relationship between operations.
Cards feature number bonds with answers shown on reverse. This set includes 90 two-sided dry erase cards (5" x 5") and instructions.
