Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

In this finding area worksheet, students solve the area of an irregular figure by reading and performing step by step operations. Students complete fourteen steps to solve and summarize finding the area.

In this triangle/quadrilateral worksheet, students use a centimeter ruler to draw triangles and quadrilaterals with given perimeters. Answers are included on page 2.

Students decide what body measurements they need to make garments such as a pair of pants. They make a list, and work with a partner to take and record those measurements in centimeters. They discuss the use of centimeters.

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Pairs of geometry whizzes work together to determine which of three differently shaped cylinders will have the greatest volume. Pupils cut out the three rectangles embedded in the plan, and tape them together to form a cylinder. From...

Students are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Students recognize and measure geometric shapes within abstract art. They examine quilts for shapes and they each make their own quilt from squares using geometry and measurement.

Students are introduced to the concepts of perimter, diameter, circumference and measurements. In groups, they complete two worksheets in which they determine if the ice dimensions make a difference in the way it floats. They discuss...

Students measure a set of Russian dolls using the metric system. In this measurement lesson plan, students identify certain relationships between sets of measurements by measuring a set of Russian dolls and presenting their findings to...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Students create a classroom quilt that illustrates the many unique ways that students use math skills.

Students use compasses and grids to map the locations of artifacts found in a simulated dig site. In groups, they role-play as future archeologists excavating a school site. Groups begin at their assigned datum and site the artifacts...

You're going to wish you had a watermelon for this instructional activity! Class members read about watermelons and make a salad in class to sample. They also perform estimates, measurements and calculations on a watermelon. They predict...

Fourth graders explore the weapons of the Aboriginal people.  In this fourth grade math lesson, 4th graders create charts, tables, or diagrams to represent patterns and relations.  Students investigate which dart length has the...

Students complete computer activities about estimating if items are more or less than a given amount. In this estimation lesson plan, students also estimate measurements around the classroom.

Young scholars read and discuss the story The Corn Dolly by Terry Jones. The teacher shows the class a corn dolly and they need to design and construct furniture that is appropriately scaled for that specific dolly.

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Learners confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

For this cylinder worksheet, students compare three different cylinders to experiment which one has the greatest volume. Students interact with rectangles as they experiment with the cylinders.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Fourth graders find the area and perimeters of squares and rectangles using a calculator to check their multiplication. They use the appropriate formulas to find the area and perimeter of the given geometric shapes.
