After lengthy discussions and explorations of different units of measurement regarding length, weight/mass, and capacity, we began to try to convert units of measurement. Ex. How many yards are in 18 feet?
To do this in an organized way, we used our handy T-chart. As we practiced several conversions, the children began to see the multiplication and division relationship. Because we still sometimes get confused about when to multiply or divide to get our answers, we are still going to start with the T-chart so that our rule is more obvious. Then we may move to a higher-level operation than simply listing. Some children are still more comfortable listing than multiplying or dividing, but are making larger jumps to help them be more efficient.
We made our "Big G" to help us see the relationship between units of capacity.
