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...

How do you see yourself? Young mathematicians consider whether it's possible to view their whole bodies in a mirror with a length that is half their height. They write a letter to a friend explaining their positions mathematically.

Can the force of falling water through a tube vary by altering the diameter of the tube or its height? That is what physical scientists aim to discover in this activity, the third in successively more revealing activities on the power of...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

It's no fun catching a fungus. Scholars first investigate how the seasons affect the angle of the sun and the lengths of shadows. They then apply right triangle trigonometry to determine the height of trees based on their shadows to...

Enhance your math lesson with a series of pictures that illustrate different math concepts. The vocabulary includes a variety of ideas and pictures including fractions, ordinal numbers, picture graphs, and number lines.

Elevate your fifth graders' understanding of math concepts with a series of vocabulary posters. Featuring terms concerning probability and statistics, measurement, algebra, and decimal place value (and many more), the posters are...

Math is a lot like building blocks—it requires a solid foundation. A short performance task has pupils consider the volume of a cubic block. It then asks mathematicians to find the surface area and volume of a prism made from stacking...

NASA's LCROSS mission is dropping a probe into a lunar crater. Groups design a system to travel down a zip line and drop a marble onto a target in the classroom. The groups then modify their designs based upon testing. 

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

Let the good times roll as young thrill seekers build a roller coaster on school grounds. Future engineers design and build a roller coaster from flexible tubing. The roller coaster is for a marble, so there will be plenty of room to let...

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Second graders examine the metric system. For this metric system lesson, 2nd graders compare measurements of common objects in metric units. Students compete in a garden scavenger hunt.

Learners complete word problems dealing with perimeter, area, length of sides, and more. They complete 10 multiple choice word problems.

Friendly Plastic is a fun art medium created by Amaco Clay Company. It is versatile and results in a beautiful end product. With this resource, young artists can recreate a famous painting using Friendly Plastic. What a fun way to study...

Young scholars practice observation techniques to improve their drawing skills. In this drawing technique lesson, students assess drawing as an art media and discuss realism. Young scholars view examples of animal drawings and practice...

Learners collect data from China's population growth and determine the mean, median, and mode from the data. In this data lesson plan, pupils determine probabilities and use them to make predictions.

Students estimate heights and lengths of objects. In this measurement instructional activity, students estimate the length and height of various objects using non-traditional tools of measurement. This instructional activity also...

In this metric units of measurement worksheet, students read information about estimating lengths and masses, then solve 65 problems. Sample problems with solutions are included.

In this area of polygons worksheet, students solve 7 short answer and multiple choice questions about area.  Students find the area of triangles given base and height, or points in the coordinate plane.

For this measuring lengths worksheet, students determine which units to use when measuring lengths, estimating lengths, and the errors made when measuring, Students estimate the lengths of each of the lines illustrate to the nearest...

Learners measure the length, width and height of different materials.  For this design lesson students complete a lab to see what engineers need to consider when planning a structure.

In this volume worksheet, 10th graders solve 10 different word problems that include determining the volume in each one. First, they determine the ratio of their radius given the cubic meters of a sphere. Then, students determine the...

Learners pick different objects and measure the shadow they cast. In this geometry lesson, students experiment with shadows using a flashlight and an object to cast a shadow. They measure and differentiate between the shadow and the real...
