How to play
How to play
Players spin a spinner and decide where to place the digit within a number sentence to reach 1000.
Students find a partner and a 0-9 dice or spinner.
Draw a game board so each student has the same one: _ _ _ + _ _ _ + _ _ _ = ____
Each player takes a turn to spin the spinner and performs a physical movement the number of times shown on the spinner, eg. Spinner lands on 9, player performs 9 reps of the chosen movement, eg. squats / star jumps / push ups, etc.
Players then decide where to place that digit in their number sentence (equation).
Students spin the spinner 9 times each.
The person whose sum is closest to 1000 is the winner!
Share thinking with a partner and record in mathematics journal or workbook where appropriate.
