Mixed Subtraction with Space — Grade 1

Some rows here are take-away-and-find-the-result; some are find-what-was-taken. In the first a written number leaves a group of rockets, planets and a star and the child counts what remains; in the second the result is shown and the child works out the part that left. Mixing the two is real Grade 1 practice — it asks a child to notice which kind of question each row is before solving. All of it stays within twenty, so the space things on the page are always few enough to count and be sure.

A page that asks only one kind of question lets a child coast; a mixed page does not. Alternating result-unknown and missing-part rows keeps attention on the meaning of each problem, which is why mixed practice is valuable at Grade 1. The within-twenty range and pictured space things keep the focus on thinking, not on big numbers.

Children who like space enjoy not knowing which question is coming next, and it keeps a small group thinking. When this feels easy, try mixed subtraction with sports gear (black & white), or mixed subtraction with valentine pictures (black & white).
