Even kindergartners can draw triangles in circles, but the assessment task requires a bit more geometric knowledge. Scholars investigate triangles that have a diameter of a circle as one of its sides. They must consider triangles that...

Laws are meant to be broken, right? Learners derive the Law of Sines by dropping a perpendicular from one vertex to its opposite side. Using the Law of Sines, mathematicians solve for various parts of triangles.

Don't just go through the steps to solve an algebraic equation, show learners how to balance an equation with visual models. The packet introduces the idea of mobile balances to reinforce the idea that both sides must match to make the...

Cubic crystals can have 6, 8, and even 12 sides. Here is a presentation that shows pupils three different kinds of cubic crystalline structures: cubic, body-centered, and face-centered. These structures are then applied to three...

Is losing cultural traditions the cost of social progress, or should people make stronger efforts to preserve these traditions? High schoolers watch a short film about the native Yup'ik people in Alaska and how they handle the shifts in...

Reinforce literacy skills using a six-sided die that focuses on phonics and story starters. Scholars roll, and show what they know about blends, plots, and more! 

Learn how to solve a triangle. Young mathematicians view a video that explains how to apply trigonometry to find missing sides and angles of a right triangle. A worksheet tests their understanding of the concept.

Get young people thinking about their lives and current topics of social justice, advocacy, gender, race, and identity. After examining several works by Barbara Kruger, participants select a tag with one of the questions printed on it,...

Young mathematicians connect vectors to geometric shapes by watching a video that expresses vectors in relation to the sides of geometric figures. They then apply what they learned by completing a worksheet of practice questions.

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Measure health as a triangle, with each side representing different aspects of health: physical, emotional/mental, and social. High schoolers complete a self-assessment of their health in all three areas before scoring their progress and...

Calling all spades, diamonds, hearts, and clubs! Four teams compete against one another to collect all 52 cards in a deck. Each team lines up on one side of the gym, opposite of the deck of cards. Each team member takes turns running to...

Partner up the class. Break up one set of partners and assign one as a chaser and the other as a flee'er. The flee'er runs around the gym away from the chaser. If the flee'er is tagged, then he become the chaser. If the flee'er...

Are the people on the other side of the world standing upside down? Pupils discuss the relationship between movement and position words. The unit explores the concept of reference points through animation, modeling, photography, and...

After separating the class into two teams—crows and cranes—each team lines up in the middle line of the gym with their backs facing each other. If the teacher yells out "cranes!" then all the cranes run to their side of the...

Assign a tagger, and everyone else as runners. The tagger will tag people at random. Persons tagged must go to the other side of the gym court to perform a skill. Once they are done, they can go back in the game.

Have the class line up on one side of the gym. Choose one person to be the tagger. When the tagger yells "blob tag!" then the whole class runs across the gym while trying not to get tagged. Anyone that's tagged, now becomes part of the...

Who said pizza and tag don't go together? Assign one person as the "chef" to be the tagger and to stand in the middle of the gym. Divvy the rest of the class into three equal groups of "toppings" (ex: cheese, pepperoni, onion). Have all...

What sets of whole numbers make up the measures of side lengths in right triangles? Pupils use an interactive triangle to learn about Pythagorean triples. Individuals find missing values in triples and learn more about Pythagorean...

How can a magnifying glass or reading glasses make things appear larger? Scholars simulate moving a lens closer or farther from an object to observe the resulting image. They also alter the lens focal length. The simulation shows the...

Most pupils don't know what a telegraph is, much less how one works. A secret simulation has scholars pick the size of the primary and secondary loops, the battery voltage, and which letters in the Morse Code they want to transmit. They...

Get a better understanding of the trigonometric functions by taking a look at the flip side. Pupils create angles within a unit circle and compare the values of the standard trigonometric functions to their reciprocal functions. The...

A change is coming. Pupils use unit cubes to investigate how changes in the length, width, and/or height affects volume and surface area. They extend the results to write and test predictions on the effect of changing multiple sides on...

All is not simple in the garden of rationals and irrationals. Learners use a context of a garden to practice simplifying irrational numbers involving radicals. They also find areas of garden with irrational side lengths.
