how many cups to get to a gallon
At our blank look, she grabbed a pen and drew a diagram like the one above... It's like the woman who swallowed a fly for cups and quarts! It still takes a few minutes of mental visualization, but with this diagram in mind, you can easily figure out that there are four cups in a quart, 16 cups in a gallon, and so on. Fingers crossed--with luck we'll never find ourselves in this particular grocery store conundrum again!
