Task# Estimating Products of Decimals

Illustrative MathematicsVaries

The purpose of this task is to help students estimate products of decimal numbers. Estimation is a valuable strategy when deciding where to put the decimal point when multiplying decimals. Although students will learn an algorithmic approach to multiplying decimals in grade 6, making sense of the context is a powerful tool that can support students' developing fluency. In order to promote sense-making, this task might work best before a teacher explains an algorithmic approach, so that students don't just carry out computations and look to see which choice is closest.
