Identifying and verifying reproducible patterns in mathematics is an essential skill. Mathematicians identify the relationship of sides when an angle is bisected in a triangle. Once the pupils determine the relationship, they prove it to...

How do you fit a tape measure around the Earth? No need if you know a little geometry! Pupils begin by extending their understanding of the Side Splitter Theorem to a transversal cut by parallel lines. Once they identify the...

In this linear equations worksheet, students solve and complete 20 different problems that include using the order of operations. First, they distribute to remove the parentheses and combine like terms. Then, students move variables and...

Tenth graders solve and complete 14 different geometry problems. First, they find the area and circumference of a circle with a given radius. Then, they find the area between a circle and an inscribed equilateral triangle given the...

Challenge your geometry class with this connect-the-dots activity! Scholars use a ruler to complete simple shapes through connecting dots in 6 shape-identification problems, and identify it from 4 choices: triangle, square, rectangle, or...

Designed to encourage readers to consider both sides of of the question of whether Ender is responsible for the death of all the buggers, individuals search for examples from Orson Scott Card's popular science fiction novel, Ender's Game...

"Alleys" is a drill or game-like situation to practice what has already been taught in previous lessons. The tennis court is divided in half, left side and right side, so that each pair of players has an alley. The goal is to aim for the...

Because most children with visual impairments don't reach and grab things at a young age the way sighted children do, they need additional supports to build up their fine motor skills. Here, they work on the pincer grasp, using their...

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...

Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

Here's some very interesting circles for your very interested pupils. A performance task requires scholars to sketch a pair of orthogonal circles so the centers are the endpoints of one side of a triangle. They draw an additional circle...

Who was Horemheb and why is his tomb so famous? An fascinating resource uses virtual reality tools and even comes equipped with the ability to use a VR headset. Learners view information panels to the side of the location to understand...

Let imaginations run wild as participants design animal pens. A performance task challenges young mathematicians to determine the perimeter or a missing side length of different animal pens. They then design pens that meet given...

Students write a biographical poem about themselves. They observe a teacher-led demonstration, write an autobiographical poem and a biographical poem about a famous person using a template form, and display the poems side-by-side.

Geometry students use hinged mirrors to discover that the regular polygons are composed of triangles tessellating around a center point. They sketch triangles on paper models of the regular polygons having 3 to 10 sides and compute the...

Do talk back! The transcript of one side of a telephone conversation launches a study of dialogue. Class members imagine the response of the speaker on the other side of the conversation and record these responses on the provided...

Logan’s Lament, a speech delivered by Mingo Chief Logan in 1774, provides pupils with an opportunity to not only study the historical events surrounding the battle between Native Americans and the Europeans for the West Virginia...

Plus one volleyball begins like a regular game of volleyball. The receiving team must play the ball twice on their side before returning it over the net. Now the serving team must play the ball three times before returning it over the...

“Rule your mind or it will rule you."—Horace. Black Tiger Academy’s martial arts lesson 14 of 20 introduces the class to dietary fats. There are good fats and not so good fats, and this activity helps them identify which is which. Then...

Here is a game that can be played by any age level. Just make some small modifications appropriate for your grade level. The premise of the game is to have the fewest balls on your side when the whistle blows to end the game. So given...

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...

Challenge scholars to prove the Pythagorean Theorem geometrically by using a cut-and-paste activity. They then must solve for the missing sides of right triangles.

Show your class that finding angle measures is a regular calculation with a resource that provides 12 problems dealing with the measures of angles in regular polygons. Pupils use formulas for the sum of measures of angles in a polygon to...
