Halves to 12: Cut Each Group into Two Equal Parts

A dashed orange rule runs straight through the middle of every group on this 1st grade doubles and halves page. Six cards are laid out two across and three down, all labelled half, and each holds a set of animal pictures arranged in two equal rows with the cut line between them. Under the box the number of animals is printed with an equals sign and two empty answer boxes: 12 =, 10 =, 8 =, down to 2 =. The child counts one row, writes it in both boxes, and the sentence reads 12 = 6 + 6.

Halving is subtraction wearing an unfamiliar coat, and children meet it far less often than they meet taking away. Setting the groups out as two matched rows is what makes it visible: the answer can be read off the page by counting either row, so the arithmetic never blocks the idea. The two boxes are the part worth watching. A child who writes different numbers in them has not understood that a half is a fair split rather than any two parts, and that misconception hides easily in a spoken lesson. Twelve is the largest group here, and the smallest can be as low as 2 = 1 + 1.

Halves to 20 with pictures continues into the teens, doubles to 14 is the same page in reverse for building the facts the other way, and number walls to 20 puts the sums these halves come from into a structure.
