About this game

One fewer (from 5 to 2)

One fewer (from 5 to 2): a free Kindergarten math game for ages 5-6. Each round draws 5 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

Taking one away sounds simple until three groups sit side by side. One fewer (from 5 to 2) is a Kindergarten game about that single step back. A picture shows two to five cups, hamburgers, hams or bananas. Your child counts them, then taps the group with one fewer, from two or three pictures. The instruction is read aloud, five pictures make a round, and every answer is checked and explained: there are five cups, and one fewer than 5 makes 4.

One fewer is the number just before. The hint says it aloud: count, then go back one number, like a countdown. Knowing it without recounting is a first subtraction fact.

On the three-picture cards, the smallest group tempts a child who only heard fewer. Five cups come with choices of four, three and two, and two is the fewest. Two is fewer. It is not one fewer. Ask, "Is that one fewer, or more than one?" Praise the exact step: "You took away just one."
