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.

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Give pupils a ruler and this instructional activity so that they can practice measuring down to the quarter inch! Drawings of six various objects are depicted for them to apply their measurement skills to. The assignment concludes with...

Young scholars use similar triangles and a sight tool to find the height and distance between large objects. In this similar triangles lesson plan, students use a constructed sight tool to measure the distance and height of an object...

Hook your charges on how to solve a real-world art problem with mathematics by showing works of Christo. You can find eye-catching images on the Christo and Jeanne Claude webpage. Here, math learners help Jean Claude and Christo prepare...

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Estimate the value of one of the most famous irrational numbers. The hands-on instructional activity instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

Apply, apply, apply! A measurement activity applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method...

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

Remodeling projects require more than just a good design — they involve complex fractions, too. To determine whether a tiling project will fit within a given budget pupils calculate the square footage to determine the number of...

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

There's no need to think outside the box for this one! Scholars measure the length, width, and height of various boxes. Results help develop the formulas for the surface area and volume of rectangular prisms.

Observe the change in the trigonometric ratios as angles vary. An interactive provides the values of trigonometric ratios for both acute angles in a right triangle. Pupils create a right triangle to match given criteria and find the...

Examine the segment addition postulate through an online simulation activity. An interactive lesson allows scholars to manipulate points and watch as the lengths of segments change. Through their study, they are able to apply the Segment...

Could you reinvent the light bulb? Scholars tap into their inner Thomas Edisons to build a light bulb prototype out of a jar and some wires. They see how long the filament wire glows in the jar (batteries not included) to measure their...

Third graders measure wind direction. In this weather lesson, 3rd graders build a weather vane from a straw, skewer, spool, and flag. Students measure wind direction using their weather vane.

In this grammar worksheet, 2nd graders insert commas into each of the 13 sentences. This worksheet is on a second grade reading level....

You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.

Eighth graders measure in feet and inches and convert to explore the relationship between the converted measurements. In this measurement lesson, 8th graders use the whisker and box plot to represent the measurement of a cat. ...

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.

Take your class out to visit your automobile and use the tires to compute the weight of the vehicle. This is done by measuring the surface of the tire meeting the ground and the air pressure. This is a fun lesson in the relationship...

Explore the concept of measuring and recording circumference. In this physical science and measurement lesson, young learners blow up balloons, measure the circumference, and record the data on an interactive graphing website.

Students calculate the length of the classroom using non-standard units of measurement and estimation. Using a cracker box, they discuss measuring various objects in the room as a class, and independently estimate and measure the length...

Show high schoolers there is more to quadratic functions than just formulas and parabolas. Connect the math to realistic application problems with a resource that has learners consider such situations as a ball hit in the air, the...
