This resource is an anchor chart for the standard 3.MD.8. It includes the definition of perimeter, how to find perimeter when all side lengths are given, and how to find the missing side length when the perimeter of rectangles and other polygons are given.  This resource could be added to a digital learning wall for students to refer back to throughout the school year as needed. (Padlet, Google Slides, Etc.)

This resource can be used through Google Slides or Peardeck.  The Mini-Lesson will cover the following “I Can” Statement.I can find the missing side length of a rectangle when given the perimeter. 

This resource can be used through Google Slides or Peardeck.  The Mini-Lesson will cover the following “I Can” Statement.I can use the given perimeter to find all side lengths of a regular polygon. 

This resource can be used through Google Slides or Peardeck.  The Mini-Lesson will cover the following “I Can” Statement.I can find all possible dimensions of a rectangle when given the perimeter. 

This resource is a worksheet for the standard 3.MD.8.  It can be used as an exit ticket or as an independent practice. This could be used with a tech tool where students can draw directly on the document (Nearpod, Peardeck, Seesaw, Etc.)

This unit is basically chapter 5 in our Math Expressions curriculum.  If your district uses Math Expressions, then this unit will make a lot of sense to you.  If you don't have Math Expressions, this unit can still help guide you through teaching your kids meausurement using customary and metric systems.

This resource provides a multiday station-rotation blended learning lesson plan for teaching Area and Perimeter.  

This short video and interactive assessment activity is designed to teach third graders about area in grid.

This short video and interactive assessment activity is designed to teach third graders an overview of area of squares and rectangles - word problems.

This book is a "flexed" version of CK-12's Basic Geometry that aligns with College Access Geometry and contains embedded literacy supports. It covers the essentials of geometry for the high school student.

CK-12 Foundation's Geometry FlexBook is a clear presentation of the essentials of geometry for the high school student. Topics include: Proof, Congruent Triangles, Quadrilaterals, Similarity, Perimeter & Area, Volume, and Transformations.

In this lesson, students explore perimeter by measuring and determining perimeters of classroom objects and solving problems about perimeter.

A structured geometry program teacher edition of daily lesson plans and teacher supports to accompany the College Access Reader: Geometry student edition.

Students work as engineers and learn to conduct controlled experiments by changing one experimental variable at a time to study its effect on the experiment outcome. Specifically, they conduct experiments to determine the angular velocity for a gear train with varying gear ratios and lengths. Student groups assemble LEGO MINDSTORMS(TM) NXT robots with variously sized gears in a gear train and then design programs using the NXT software to cause the motor to rotate all the gears in the gear train. They use the LEGO data logging program and light sensors to set up experiments. They run the program with the motor and the light sensor at the same time and analyze the resulting plot in order to determine the angular velocity using the provided physics-based equations. Finally, students manipulate the gear train with different gears and different lengths in order to analyze all these factors and figure out which manipulation has a higher angular velocity. They use the equations for circumference of a circle and angular velocity; and convert units between radians and degrees.

CK-12 Geometry Teacher's Edition covers tips, common errors, enrichment, differentiated instruction and problem solving for teaching CK-12 Geometry Student Edition. The solution and assessment guides are available upon request.

In this lesson, students will work with partners and use square blocks or tiles to find different shapes for Grandpa's pool of 24 square units. Then they will find the perimeter of each shape for fencing.
