This Instructional Activity is a part of the Lesson 15, Unit 2, Grade 6. We have been working with the division algorithm and have applied the algorithm to division of decimals. Let's see if there is a way to make our computations more efficient. Display the given expression. In the past lesson, we utilized the powers of ten to help us estimate and find quotients. Discuss with your partner if it would be efficient to use a power of ten to estimate or to evaluate this expression.
