In this ellipse worksheet, students learn the difference between an orbit and an ellipse. They draw ellipses and calculate the distance between foci, they calculate the length of the major axis and they determine the eccentricity. They...

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...

What locations on Earth get the longest number of hours of daylight in the summer? Hint: It's not the equator! Use real-world sunrise and sunset data to develop trigonometric models that can be used to estimate the number of hours of...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson plan that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

The Pythagorean Theorem is a geometry pupil's best friend! Learners explain the equation a1b1 + a2b2 = 0 for perpendicular segments using the Pythagorean Theorem. They are able to identify perpendicular segments using their...

Geometry meets earth science as high schoolers investigate the cause and features of the four seasons. The effects of Earth's axis tilt features prominently, along with both the rotation of the earth about the axis and its orbit...

How many planets can you name? Did you get all 13 in our solar system, including the dwarf planets, or were you surprised when you read there are 13 planets? The instructional activity helps scholars understand the scale of the universe...

Customers often want ribbon around fancy cakes, but how does a baker know how much ribbon to buy? Scholars view a cake with multiple layers in different geometric shapes. They must figure the perimeter and circumference and add them...

Seventh graders create and perform a skit that demonstrates their conflict resolution skills. They begin by examining the process of crafting a performance and review what they have learned about conflict resolution. Next, they...

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

Finding the area of a rectangle is the focus of this metric worksheet. Here, mathematicians use their knowledge of finding the area of a shape in meters to discover how much material can fit inside a shape.

Reinforce math vocabulary instruction with a set of flash cards. Fifty-six cards offer either a bold-face word or a picture representation equipped with descriptive labels. Terms include centimeters, gallons, square units, and more!...

Fifty-four flashcards make up a set to help reinforce math vocabulary. The set offers two types of cards; a word card printed in bold font, and a definition card equipped with an example and labels. Terms include capacity,...

Did you know some retailers use curved mirrors in their fitting rooms to make customers look thinner? Pupils view themselves in convex and concave mirrors to understand the difference. The resource includes big ideas for multiple age...

Give your scholars the support they need to work with formulas. A reference page offers definitions and picture examples of perimeter, area, surface area, volume, the Pythagorean theorem, a variety of shapes, and more. 

Take a seat on the parade route with a holiday-themed set of word problems. Young mathematicians answer questions based on the annual Macy's Thanksgiving Parade in New York City, including finding the average number of members in a...

Don't worry, optics is a light topic! The presentation covers reflection, refraction, fiber optics, mirages, prisms, rainbows, dispersion, mirrors, lenses, telescopes, diffraction, the human eye, and much, much more. Presentation is...

It's always nice to hear from friends. Your budding mathematicians read letters from pen pals and convert customary measurements into metric units and vice versa. They also write letters to an imaginary pen pal using metric units.

Getting the right measurements can save a lot of time and money in the real world. Learners are introduced to unit conversion and how to accurately go from one unit to another. The first pages are notes and then the packet finishes with...

Curves ahead! Develop a numerical measurement of curvy-ness. The class is challenged to come up with a definition of curvy that can be applied to curves. The class members use their defined measurement to describe a curve.

Enrico Fermi, the physicist responsible for the first nuclear detonation, was known for his ability to estimate with little or no data. Use this task to have your classes practice their Fermi skills. They estimate the magnitude of three...

Here's a resource with more bounce for the ounce! Engage your physical science class with an interesting interactive that allows individuals to perform tests with a mass attached to a spring. Participants can customize the scenario by...

Lead your class on a search for precious bones. Using a presentation, the class investigates the golden ratio in art and nature. Groups of pupils measure specific bones and find the average ratio for the class. To further cement the...
