When we need to calculate something fast and it doesn't need to be precise, this is called estimation. We begin using this skill at an early age and continue to use it in everyday life for things like shopping, budgeting, approximating time and objects, and many others. Since the real-life application of estimation techniques is so valuable, we need activities to improve our students' knowledge in this area so they are prepared for any situation requiring an estimate. Here are 20 creative math activities perfect for kids and teens to learn the art of rounding.
1. Estimation Jars
