For capasity- I make a circle with my arms and make them come together and Say "the amount a container" and I leave one arm in a half circle and use the other arm to act like I"m pouring something into it. Did you teach gallons, quarts, and pints? If so, I have a cute song that I made up and the kids love it!! Hope this helps!!
To the tune of Sally the Camel:
There are 4 quarts in a gallon
There are 4 quarts in a gallon
There are 4 quarts in a gallon
So roll baby roll, Boom boom boom
There are 8 pints in a gallon,
There are 8 pints in a gallon,
There are 8 pints in a gallon,
so roll baby roll, boom boom boom
There are 16 cups in a gallon
There are 16 cups in a gallon
There are 16 cups in a gallon
so roll baby roll, boom boom boom!
