Math: 2-D Geometry and Measurement


I trust that your student delivered the Family Letters that accompany our new math unit to you. This week we started Unit 4, our first geometry unit of the year. Our classroom has been covered with rulers and yard sticks and meter sticks as the students have been busy measuring things around our classroom.

This week we have been working to:
  • Review the lengths of units of measure
  • Use U.S. standard and metric units to accurately measure length
  • Estimate lengths based on common units
  • Determine when estimates or exact measurements are needed
  • Find perimeter using standard units
  • Recognize and explain possible sources of measurement error
