Fact House Practice to 10: Six Houses for Fluency

Grade 1 Operations & Algebraic Thinking Common Core

Six fact family houses, every trio within 10, are printed on this Grade 1 page. Each roof carries three numbers, and each house holds the same four facts underneath — add them both ways, subtract them both ways — with an empty box at the end of every line. The format is the one children already know from earlier houses; what has changed is the quantity: six roofs, twenty-four boxes, and small friendly numbers the whole way down.

This one is built for the routine slot rather than the teaching slot. The concept has already been introduced, the numbers stay easy, and the point is repetition — the sort of page that works as morning work, as an early-finisher task, or in a folder a child can pick up without any instruction from an adult. Fluency in fact families is worth that kind of drip-feed: the children who write the four facts quickly and confidently are the ones who later meet 13 minus 5 and simply recall the addition that answers it.

The sheet prints free as a PDF, and running it a few times across a term costs nothing at all. Fact families to 10 is the shorter introduction if a child is meeting houses for the first time, while fact families with a missing partner takes the same easy trios and hides a different number instead.
