Mixed Subtraction with Shapes — Grade 1

Mixed subtraction lays two row-types side by side. On one the child takes a number away from a pictured group of circles, squares and a triangle and counts what's left; on another the leftover is given and the child finds how many went. For a Grade 1 child, handling both with the same shapes is how the link between a take-away and its missing part takes hold. The within-twenty amounts keep every answer checkable, and the steady switching between the two keeps a child reading and thinking rather than coasting.

Mixed subtraction within twenty rehearses the inverse relationship between adding and taking away by putting both directions in front of a child at once. That flexibility — knowing a fact and its partner — is core Grade 1 work, and the pictured shapes keep each small problem checkable while the variety keeps the child engaged.

Children who like shapes enjoy not knowing which question is coming next, and it keeps a small group thinking. When this feels easy, try mixed subtraction with space, or mixed subtraction with trees.
