Measuring a Metre
We have started our Measurement Unit by closely checking out our metre stick. One of the expectations in Grade One is to use the metre as a benchmark for measuring length, and compare the metre with non-standard units. We estimated how many snap cubes it would take to make a metre. There were a variety of guesses (ranging from 7 to 1000). A couple of math-magicians guessed 50 AND they were very close!
How many snap cubes did it take to make a metre when we played On the Metre Mark?
One of our students came up with a brillant way to keep track of his counting! He put a red cube at every 10th cube. That way, he and his 'math buddy' could count by 10's when they were counting to the metre mark!
