What can shadows tell us about the changing season? Over several months, astronomy learners record length and position of an outdoor object's shadow, such as a flagpole. They apply the data to a growing hypothesis and note the...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

An engaging lesson which has elementary learners measure weight to the nearest pound and construct and interpret a bar graph! They measure length using non-standard units and determine area using square tiles. Pupils round their birth...

Students discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e., interpolation...

In this mathematics worksheet, students model a batting stance with a regulation size baseball bat. Then they model the batting stance with a souvenir miniature baseball bat. Students measure the length of each bat in centimeters and use...

Students measure an assortment of items using metric measurements. In this measurement instructional activity, students measure using length, mass, and volume units of measurement. They convert between units. Students learn a mnemonic to...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.

Middle and high schoolers use the Pythagorean Theorem to determine the length of the sides of a right triangle. They solve distance problems. This one-page worksheet contains 10 multiple-choice problems. This is self-checking worksheet.

In this composite figures worksheet, students solve twelve short answer problems. Students find the area of figures composed of various polygons given a sketch of the figure with side lengths labeled.

Some formatting issues will need repair (a few overlapping text boxes and pictures), but overall this is a comprehensive presentation on how light reflects off of spherical mirrors. Both convex and concave mirrors are explained,...

How many items can your learners find that are approximately one inch in length or width? Using this graphic organizer, they find nine, labeling and drawing each. A line that is 1-inch is provided at the bottom of the page, or you could...

Try introducing this assigment on converting measurement by presenting a scenario: "Last night I found a recipe for cookies, and it called for a half pint of butter. All I had was measuring cups - what should I do?"...

Humongous vegetables can inspire and awaken your mathematicians to the large math concepts in our Common Core standards. What is the secret to growing such gargantuan garden objects in Alaska? In the state that is closest to the...

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,...
