Brain research teaches us that making a connection to something familiar helps students remember.
My students were recently working on linear measurement. One of the important concepts is remembering the different units, and having a good "feel" for the size of the units.
Here's one of the connections we make:
My kiddos are VERY familiar with the base ten blocks. It's an important part of second grade math, so we use them frequently.
Another trick I teach them:
a centimeter is about the size of an M&M!
They always remember that one!
Here's another connection:
Again, they're quite familiar with those base ten blocks, and have often lined up two of the longs, so it's easy for them to estimate something that is 20 centimeters long!
Since the metric system isn't standard in the US, here's a connection for inches:
This trick for a foot was taught to me by one of our former custodians.
Those custodians are pretty smart! The floor tiles they used in our school are exactly a square foot each! That makes measuring our floor super easy! Of course the kids have to get out the rulers and see for themselves, but it's true! Plus it sure helps the kids remember how big a foot is.
You know what else helps them remember a foot?A ruler!
