## Everyday Math Unit 9: Coordinates, Area, Perimeter, Volume

Updated 7-30-15

In this unit, students will study geometry, with a focus on area and perimeter.

Topics studied include:

Download the Unit 9 Family Letter for more information about this unit, including vocabulary definitions, new algorithms, at-home suggestions, and answers to selected study link questions. Scroll down the page to find games, skills practice, and video tutorials specific to this unit of study.

One of the most important skills students will need for fifth grade math is automatic recall of addition, subtraction, multiplication, and division facts. I strongly encourage all students to practice math facts at home for at least 5 minutes each night. Our class will be charting progress as we take Facts Master practice tests each week, with the goal of correctly answering all 300 problems in under 10 minutes. Use this online stopwatch to time yourself!
