About this game
Take away 1 (from 10 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.
Ten hamburgers on one picture, lined up in two rows of five. Take away 1 (from 10 to 2) is a Kindergarten game that keeps asking for one fewer, now with groups as large as ten. Your child counts the cups, hamburgers, hams or bananas in the picture, then taps the group with one fewer, out of two or three pictures. The instruction is read aloud, a round draws five pictures from 66, and every answer is checked and explained: there are seven cups, and one fewer than 7 makes 6.
Past five, counting one by one gets slippery. The bigger pictures sit in rows of five, so ten is two full rows and nine is a row with a gap. Seeing that one fewer is the number just before, even at 9 or 10, is the start of counting back and of subtraction.
On the ten-hamburger card, the choices are seven, eight and nine. A child who loses the count halfway taps eight. Eight is two fewer. Cover one hamburger with a finger and ask, "Which row lost one?" Then name the method: "You used the rows instead of starting over."
