In this calculus worksheet, students identify terminal and coterminal angles using the unit circle. They identify coterminal angles between 0and 2pi and between 0 and 360 degrees. There are 34 questions with an answer key.

In this geometry worksheet, students define important vocabulary dealing with circles. They measure cricles to the nearest degree. There are 11 word problems to be solved.

Eleventh graders explore the three basic trigonometric functions. In this trigonometry/Algebra II lesson, 11th graders use GeoGebra and the unit circle to define the ratios of sides is a right triangles as they examine the full domain...

Fifth graders practice measuring angles by using protractors.

Students investigate why the North Star was important for navigation, how stars move across the night sky, how to locate the North Star, how to make a crude sextant, and how to determine latitude using a sextant and the North Star. They...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Sixth graders identify benchmark angles as they are embedded into a circle grid. They observe the teacher using an angle ruler and complete a Star Spangled worksheet, play the game Tomb Robbers, and as a class discuss their game winning...

Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

First graders draw and describe various types of polygons. they investigate their own environments for examples of polygons. After reading the book, The Greedy Triangle, they discuss everyday objects that are polygons. They create shape...

For this math exam worksheet, 8th graders review geometric and algebraic concept including angles, polygons, equations, factoring and addition and subtraction, quadrilaterals, trig and circles. They take a comprehensive...

Fifth graders measure specified distances when given perpendicular lines. In this measurement lesson plan, 5th graders draw the lines themselves.
