In this scale drawing worksheet, students use the scale drawing of a building to calculate the length of two walls. They compute the amount of molding they must order (perimeter). Students calculate the area of the house to determine how...

Young scholars use calculations to complete the same journey of Lewis and Clark. They answer questions along their way and share information they gather with the class. They compare their calculations with those made by Lewis and Clark.

Students solve the area for parallelograms,squares, rectangles, trapezoids, and triangles. In this geometry lesson, students compare and contrast two dimensional shapes and apply their properties to solving real life scenarios. This is a...

In this online interactive worksheet, students determine the missing length of a geometric shape and then check their answers.

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.

You've heard that it is true, but can you prove it? Scholars learn the Pythagorean Theorem through proof. After an overview of proofs of the theorem, learners apply it to prove triangles are right and to problem solve. This is the second...

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...

Discover a renewed appreciation for the highway transportation department. with a lesson that has scholars design a highway route that meets certain conditions, including traffic flow, curves, speed limits, financial costs, and...

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Here is an engaging lesson which invites learners to cut a strip of adding machine tape that is their height. They decorate their strip, arrange the strips from shortest to longest, and then discuss predictions.

Your carpenters will enjoy learning scaled drawing techniques and applying their new knowledge to make some real-life scale drawings of gardens. Your carpenter scholars will be reviewing some basic skills in a warm-up section of problems...

In this surface area and volume worksheet, 10th graders identify and complete 3 different problems that include determining the surface area and volume of cubes. First, they use their ruler to find the width and height of each cube....

Determine how cup stacking relates to linear equations. Pupils stack cups and record the heights. Using the data collected, learners develop a linear equation that models the height. The scholars then interpret the slope and the...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...

Students cut yarn into several different lengths and fold paper in half, using skills for measuring and fractions. Then they use unconventional items (yarn) as tools to create mirror-image art and experience first-hand the math idea of...

What sets of whole numbers make up the measures of side lengths in right triangles? Pupils use an interactive triangle to learn about Pythagorean triples. Individuals find missing values in triples and learn more about Pythagorean...

The narrator of a short video explains the steps in constructing a triangle given the measure of two angles and the length of the side between the angles. The resource provides opportunities for pupils to practice the skill with two...

What's one more app? After reviewing how to calculate missing side lengths or angle measures in a right triangle, pupils create instructions for a phone app to do all of the tedious work. They must consider all nine cases of known...

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

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.

In this length and width learning exercise, 2nd graders draw 6 specific items or objects that are the following measurements: 6 feet tall, 3 inches long, 9 inches long, 1 inch wide, 25 feet long and 4 feet long.

In this how far along each line are the arrows worksheet, students determine the length on sixteen different lines. Students show the percentage and/or decimal equivalent of their answers to each line.

This problem solving PowerPoint presents a detailed, logical sequence of steps to follow in order to solve a story problem. The thinking processes described are given in text and represented by a visual model. After discussing the...
