Identify efficient and inefficient multidigit subtraction strategies.

In pairs, students race to reach the target number by adding 1, 2, 3 or 4.

Start with the 'Got It' target 23.
The first player chooses a whole number from 1 to 4.
They throw and catch the ball, clapping their hands the number of times of their chosen number, eg.:
- 1 = throw ball in air and clap once before catching.
- 2 = throw ball in air and clap twice before catching.
- 3 = throw ball in air and clap three times before catching.
- 4 = throw ball in air and clap four times before catching.
Players take turns to add a whole number from 1 to 4 to the running total. Record on a whiteboard.
The player who hits the target of 23 wins the game.
