Modeling Multiplying Decimals Due Wednesday 9 10 Math Vide Students will shade hundredths grids to model the overlapping tenths to show the product. These drawings are the easiest to use when modeling the multiplication of a decimal by a whole number. for example, if i give the problem 0.42 x 5, students can draw five blobs, label each 0.42, and move on. the difficulty with this strategy is that it does not lead the students towards the product for this problem.
