Subtract a Number with Dinosaurs — Kindergarten

Each problem shows one group to count and one number to take from it: a set of a T. rex, a stegosaurus and a raptor, a minus sign, a written numeral, and an empty answer. The child finds how many dinosaurs are left by counting the pictures and then subtracting the number, counting back from the total. Because amounts stay within ten, the answer is always reachable by counting rather than by recalling a fact, and the page quietly links a pile of pictures to the figure that means the same amount.

Pairing a countable group with a number to subtract builds two things at once — the take-away meaning and the first comfort with written numbers. Because the dinosaurs stay pictured and the totals stay within ten, the child can always fall back on counting to check, so the symbol is introduced on a foundation they can trust.

Children who enjoy dinosaurs settle into this quickly once crossing-out feels easy, and it suits a calm independent task. When this feels easy, take some away in subtract a number with easter, or try subtract a number with fruits.
