Mixed Subtraction with Vehicles — Grade 1

On this Grade 1 sheet some buses, trucks and a digger rows hand the child a number to subtract and ask for the result, while others hand over the result and ask for the missing part. Practising both at once — within twenty, with the vehicles pictured — keeps a child thinking about which question is being asked and stops subtraction from collapsing into a single automatic move. And because the amounts are small and shown as pictures, every answer can be checked by counting rather than guessed.

Practising the two forms together helps a child see them as the same relationship from different angles rather than two unrelated skills. That is the heart of Grade 1 subtraction sense, and a mixed page of within-twenty vehicles problems builds it without ever leaving numbers a child can check by counting.

Children who like vehicles enjoy not knowing which question is coming next, and it keeps a small group thinking. When this feels easy, try mixed subtraction with zoo animals, or mixed subtraction with bakery treats.
