Tilly's 1 More, 1 Less Game

Kindergarten math with Tilly the turtle: flashed quick looks at numbers to 20 on two 10-frames, then roll and count out 13 counters, see 1 added or taken away, and find 1 more and 1 less on a 1 to 20 board. Every direction is narrated.

• 16 narrated scenes: 4 quick looks, a count-out build, 7 numeral questions and a pick-two board
• Spoken hints and another try on every wrong answer

• Count out a number of counters up to 20 on two 10-frames.
• Say how many there are after 1 counter is added or taken away, without counting them all again.
• Find the number that is 1 more or 1 less than a number up to 20.
• Find the number in between, when you know the numbers 1 more and 1 less.
