Review how to estimate sums and differences with the notes below. You only round the fraction to 1, 1 or 0 then add that to the existing whole number. Think about which 2 whole numbers the mixed number falls between and which it would be closer to on a number line. Estimating Sums and Differences. Estimate the sum by rounding each mixed number. Remember to simplify when possible. 1 12 1 15 1 2 12 1 2 8 8 1 Here are the notes as a reminder of how to multiply fractions using a model. Multiplying Fractions using Models. Look at the picture. The model has been done for you. Write the answer in simplest form. 2 1 1 3 3 1 Multiplying Fractions with Models. Draw the model then write the answer. You can use the rectangle shape and lines under the star for your model. 2 x 1 Multiplying Fractions with Models Draw the model then write the answer.
