Earlier today @tomhenzley tweeted about models for teaching addition and subtraction of decimals. I've often found the 10 square and 1 square to be a useful addition to other strategies. In many classes, children are very used to the 100 square to add and subtract 2-digit numbers. It is a natural progression to use the 10 square and the 1 square to move on to decimals.
