Mixed Subtraction with Insects and Bugs — Grade 1

This Grade 1 worksheet mixes two kinds of subtraction so the same bugs keep a child thinking. On some rows a group of ants, bees and a ladybug has a written number taken away and the child finds how many are left; on others the number left is given and the child finds how many went away. Switching between finding the result and finding the missing part stops the page becoming automatic, and it keeps every row a small decision rather than a habit. The amounts stay within twenty, so whichever kind a row turns out to be, the child can settle it by counting the pictures.

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 bugs keeps the practice honest and self-checking.

Children who like insects and bugs enjoy not knowing which question is coming next, and it keeps a small group thinking. When this feels easy, try mixed subtraction with kitchen tools, or mixed subtraction with post office.
