Get third graders excited to work find area and perimeter of unit squares, rectangles, and irregular shapes. A 36-page packet comes with task cards, graphic organizers, practice worksheets, printables with squares, exit tickets, and word...

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of rectangles,...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging learners to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry lesson. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden plots that meet...

Take young mathematicians' understanding of geometry into the real world with this upper-elementary math lesson. Given the floor plans of a historic building in Tennessee, young scholars are asked to calculate its area and perimeter as...

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different area...

Third graders determine the perimeter of a shaded section by counting the number of unit squares that surround it. Each section is shaded on a small square unit grid. 

High schoolers investigate area and perimeter of various shapes.  In this area and perimeter of various shapes lesson, students record how area of shapes change when a dimension is doubled, halved, quartered, etc.  High schoolers make...

Making the transition from two-dimensional shapes to three-dimensional solids can be difficult for many geometry students. This comprehensive Common Core lesson starts with writing and graphing linear equations to define a bounded region...
