Before jumping into numeral decimals, explore them visually using this base 10 strategy. There is a set of examples to help scholars understand the concept. They color in grids to represent decimals written in a variety of ways. Some include tenths and others hundredths. After completing eight of these, they switch it around and write in decimals to represent already-colored grids. Watch for confusion with zeros here, making sure mathematicians understand that .09 is very different from .9.
