Mixed Subtraction with Classroom Objects — Grade 1

This sheet asks a child to find the result on some rows and the missing part on others, all with the same classroom objects. Taking a written number from a group of pencils, books and a globe gives one kind of answer; being shown the result and finding what was taken gives the other. Going back and forth keeps the focus on what subtraction means rather than on one repeated step. The numbers are held within twenty throughout, so each small problem stays something a Grade 1 child can check by counting.

When a child cannot predict whether the next row wants the result or the missing part, they stay with the meaning of subtraction rather than a memorised motion. That is the value of a mixed page at Grade 1, and holding the numbers within twenty with countable classroom objects keeps the practice honest and self-checking.

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