How to play
How to play
Players decide whether a number sentence is true or false by running to the respective baseline.
All students line up along the centre line.
Explain to students that the marked line to left of the centre line is 'true' and the line to the right of the centre line is 'false'.
The teacher calls out or shows a number equation and asks if it is true or false, eg. 19 + 15 = 34
Students must run to get to the corresponding destination as fast as possible deciding if the equation is true or false.
Variations
Variations
For a challenge, use 3-digit number sentences.
Play with decimal numbers.
Increase or decrease the distance to the baseline.
Vary the locomotor movement used.
Use different operations.
Have students provide reasons for their thinking.
