Young scientists grab their measuring tapes, rulers, and yard sticks as they see how big Arctic animals really are. To conceptualize the trait of height or length, each small group will measure out the entire length of an arctic animal....

Measurement devices can be used to determine the height, length, or weight of all kinds of things, even plants and animals. This presentation acts as the basis for two estimation activities. Each activity requires the children to...

Here is a straightforward example of how to apply the Pythagorean Theorem to find an unknown side-length of a trapezoid. Commentary gives additional information on proving that the inside of the trapezoid is a rectangle, but is...

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

Let physical science stars experience Newton's first law of motion by blowing marshmallows out of cardboard tubes! Using different lengths of tubing, they find that more force is needed to overcome increasing friction, and they have a...

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

What does geometry have to do with depression? It's an angle of course! Learners apply the tangent ratio to problem solving questions by finding missing lengths. Problems include angles of elevation and angles of depression. Pupils make...

First angle measures, now segment lengths. High schoolers first measure segments formed by secants that intersect interior to a circle, secants that intersect exterior to a circle, and a secant and a tangent that intersect exterior to a...

Challenge the class with inscribed circles in triangles. The assessment task requests class members use their knowledge of circles and right triangles to prove two triangles are congruent. They go on to utilize their knowledge of...

Apply geometric concepts to a design problem. Individuals examine the structural setup of the chain on a bicycle and use the measurements of the circles to determine the length of the chain. 

How do you convert from one measurement to another? Pupils use unit rates to convert measurements from one unit to another in the 21st segment in a 29-part series. They convert within the same system to solve length, capacity,...

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...
