With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

With the help of the Area Officers and Perimeter Patrol, you learners will develop a better understanding of area and its relationship to perimeter. First, they view a video clip from Cyberchase, and then they visit a website to...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations instructional activity, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become...

Third graders review formulas for area and perimeter in quadrilaterals. They arrange pre-cut twine on a centimeter graph paper to create non-congruent quadrilaterals. They calculate the perimeter and area of each form.

Children begin by making direct comparisons between objects and putting a number of objects into order according to length. They are also introduced to measuring with multi-link cubes which allows them to compare objects which cannot be...

Third graders practice measuring items by examining classroom objects.  In this geometry activity, 3rd graders utilize measuring tools to find the weight, time, length or temperature of specific classroom items.  Students...

Students compare estimated lengths with actual lengths.

Students use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the front...

In this length instructional activity, student find lengths and round, and solve addition problems, including word problems. All problems have to do with length.

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...

Reach for the STARs! Using the resource, scholars review the STAR (Stop, Think, Act, Review) method and discuss how to use it to solve a math equation. Next, small groups collaborate to solve a common problem in the classroom using the...

Third graders find areas of rectangles by using square units, apply knowledge to real-life situations, and simplify method of counting square units by multiplying the length times the width.

Pupils study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of angle.

Students measure their smile with a piece of string, which is then measured on a ruler (metric of course!). They take a piece of string and cut it to the length that matches their smile and then measure it with a ruler.

Students explore perimeter. In this geometry and measurement lesson, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...

Learners explore measurement. They use appropriate units of measurement for different sized objects. Students collect their data and enter it into an Excel data base. They graph their findings and analyze their outcomes.

Young scholars pace a Gunther Chain, a measurement used by foresters to determine distance and area. They discuss that pacing is individualized depending on age, gender, etc. They practice to find an average pace. Teams estimate, pace...

Geometers find the perimeter and area of rectangles. They discuss the definitions and characteristics of rectangles and squares. In groups, they use yarn to discover the perimeter of squares and rectangles. They count cubes to explore...

Young mathematicians calculate the area of rectangles and squares. In this geometry lesson, learners are grouped in pairs and use geoboards to construct rectangles. They calculate the area of the figure by counting the number of square...

Learners follow a series of instructions for drawing and coloring different shapes in order to learn the difference between the perimeter and area of a polygon. Then they are asked to find the perimeter and area of a 3x4 rectangular...

Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.

Young scholars assembly tops and name them 1 - 12 so that they can compare their results. They guess which top they think will spin the best and then record data on "Toothpick Top" table. Using a stopwatch or clock to measure and record...

Can your scholars find the perimeter of Peter's square of gold? They examine the shape and are given it's four equal side measurements in millimeters. Learners solve for the perimeter and should be reminded to include units in their...

In this non-standard units worksheet, students circle the best unit to use to measure given items, drawing or writing to explain their work. Houghton Mifflin text is referenced.
