Simplify division for young mathematicians by teaching them how to use friendly numbers when finding quotients. Three examples are presented in this instructional video that models the process of breaking large dividends into sums of simpler terms using multiples of the divisor. Consider pausing the video after each example, allowing learners to discuss other possible solutions involving the use of this new division strategy. View this video as a whole group during a lesson on division in order to help students become more comfortable with the operation before introducing the long division algorithm.
