Searching the internet, I happened across a great way to teach or to reinforce units of capacity. I love hands-on, interactive ways to teach and to learn math, so Measurement Man was right up my alley, I mean abacus.
My girls LOVED this activity which is the best I have found to teach this concept in a hands-on, concrete method.
I posted the link on the Flip Three Pancakes page of my website. If you liked Measurement Man, you will love the other activities I posted.
