Find the Missing Number — Furniture — Grade 1

Here a child meets the missing-number form of subtraction: a group of sofas, tables and a lamp, the amount remaining, and a blank for how many were removed. Solving it means counting up from what's left to the start, or finding the take-away that fits — reasoning about subtraction rather than just performing it. The pictured furniture and the within-twenty range keep the thinking concrete and self-checkable, so a Grade 1 child can confirm the missing number by counting whenever they are unsure.

Asking for the taken-away amount rather than the result keeps a child from running a page on autopilot — each row needs real thought about the missing middle. That is precisely why change-unknown problems matter at Grade 1, and why keeping them within twenty is important: the thinking is the work, so the numbers stay small enough to verify by counting the furniture.

Children who like furniture take to the puzzle of working backward, and it suits a child ready for a little more than plain take-away. When this feels easy, try find the missing number with hospital things, or find the missing number with ocean life.
