Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

How long of a line can you draw within this activity? Learners pick two points outside and within the map to create the longest line they can. After drawing 10 lines, learners plot the length of each line on a line plot. Then they...

Boat ramps move with waves and changes in water level. Scholars decide on the proper length for a ramp so the angle connecting both sides is appropriate. They visualize the situation and use a simulation to view the results with their...

Build a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

Fourth graders prepare two spreadsheets each with an embedded line graph that displays data about the growth of the bitter rot fungus on apples and on petri dishes that were stored in the refrigerator and the classroom. They prepare a...

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Learners solve and graph 10 different problems that are the inverses of various trig functions. First, they determine which equation is equivalent to a given equation. Then, they find an angle of a right triangle, given its leg lengths....

In this similarity worksheet, students solve and complete 7 different problems that include determining various dimensions of mirrors shown. First, they find the length of the diagonal of the large mirror in the diagram. Then, students...

Rainbow science anyone? learners put the color specturm, frequency, light waves, and wavelengths into a light speed context. They use algebraic formulas to determine the speed of each light wave length. A great way to connect math and...

Practice basic addition facts and measuring skills. In this addition and measurement lesson, students are provided with drywall tape and work in groups of four at a long table. Partners take turns generating addends and marking the...

Young learners compare the relative values of fractions by making physical representations. They fold and label strips of paper that are equal in length to represent "one whole" and the equal parts that fractions represent. Also, they...

Explore the concept of mean, median, and mode with pupils. They estimate the length of a string or the number of M&M's in a jar. Then find the mean, median, and mode of the class' estimates.

Teach your class how to improve their writing. This resource walks learners through the keys to good writing. It addresses the need for complex sentences, the use of different ways to open a sentence, and the importance of varying the...

What can jump 150 times its own length? Fleas! Assign this reading passage to your class, and they'll not only develop reading skills, but they'll learn about fleas. After reading the excerpt, they answer the questions that follow. All...

Would you use a ruler to measure the length of a soccer field? No way! Pupils explore four tools of the trade: yardstick, measuring wheel, tape measure, and ruler. They label 12 measuring tasks with the most appropriate...

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

What to wear today; such a vexing question. Spend some time introducing the names, fabrics, types, colors, and functions of various articles of clothing to your class. Each child will take turns asking each other what they are wearing....

Have you ever wondered how many ants make up an elephant? Inquisitive minds will be amazed as they use scientific notation to compute and compare the mass of an elephant to an ant. Have participants make guesses and see how close they...

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of...

Use patterns to your advantage! The Pythagorean Theorem allows learners to find missing sides of right triangles. Problems include those with both rational and irrational lengths. 

Don't be a square! Young mathematicians determine the slope and length of a line segment. They then prove whether four given coordinate points form a square.

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...
