Perimeter

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...

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...

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 students 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 instructional activity. Given the floor plans of a historic building in Tennessee, students are asked to calculate its area and...

Students investigate area and perimeter of various shapes.  In this area and perimeter of various shapes instructional activity, students record how area of shapes change when a dimension is doubled, halved, quartered, etc.  Students...

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. 

Around and in—take a different look at rectangles. A portion of a basic geometry playlist discusses the area and perimeters of rectangles. Using the formulas, the presentation works perimeter and area examples with rectangles and squares.

Follow this engaging slide show on the calculation of polygon perimeter with some hands-on measurement of perimeters to solidify the concepts. On this webpage there are interactive assessment questions and links to related resources by...
