After you have guessed your first measurement with your counters, you must sit back down while a leader measures you answer with a tape measure. The same will happen when guessing the two other measurements.
Everyone must have a go at one question first before they move onto the next question. There is a small prize for the most accurate guess for each of the three questions.
With you name counters.....
1.) Guess how long two metres is
2.) Guess 50 inches is
3.) Guess 106 inches is
This game was very successful. I found that different kids had different strategies, one child estimated there foot length and then guessed the length by walking foot to foot.
