DECIMALS: EQUIVALENCE AND MULTIPLICATION

To multiply decimals, we multiply and then count the number of decimal places to the right of the decimal point for each decimal number. We then add them together to find the total number of decimal places needed in the answer. We’ll first look at modeling multiplication of decimals to find out why we place the decimal point in the answer this way. We will use decimal squares to create the model.

After investigating decimal models, we will practice multiplying decimals and extending our knowledge with more decimal multiplication using paper and pencil.

When computing with decimals some answers can be simplified. We will examine equivalent decimals and find ways to simply answers.
