To introduce fractions as it relates to decimals, I take a piece of art and place a 100 grid on top of it. Students name how many squares out of the hundred contain a certain item in the picture. We name their answers as fractions and as decimals. For example: A fall picture contains a farm of pumpkins. How many squares have a pumpkin in them? 37 out of the hundred would be 37/100ths or .37.
Students learn the relationship between a fraction and a decimal. Beginning with hundredths also revisits place value. They will pay attention to details in art.
