In this plane figures activity, learners answer questions about the plane figures and their sides and corners. Students draw pictures to help them answer the six problems.

Students review plotting points on a coordinate plane. Individually, they add and subtrace complex numbers and graph them in a complex plane. They follow along a worksheet while their teacher lectures on the new material and solve...

Students review the lecture portion of this lesson. Individually, they graph various points on a complex plane and identify conjugates based on their location on the graphs. They complete a worksheet and review their answers to end the...

Students comprehend that the Cartesian diver is a dropper and the water and air inside it. They vary the volume of the air and the amount of water, the diver can be made to be either more or less dense than water. Pupils squeeze the...

Make all the ratio representations fit together. The 15th segment in a series of 29 presents ratio problems to solve. Scholars use a variety of representations to respond to the questions. The problem set has pupils show how the...

Students investigate organs, anatomical planes and transverse sections of the human body using gel people. In this human anatomy lesson plan, students use gel molds, gel and food items to make models of the human body. They create a...

Students identify the number of sides and corners of plane figures. In this geometry lesson plan, students read the book A Cloak for the Dreamer and identify the ways shapes fit together. Students review shapes and identify the sides and...

In this mirrors activity, students will design and draw their creation of a "Crazy Mirror Room." They must use a combination of convex, concave, and plane mirrors and they must write a description of what a person's reflection would look...

Fifth graders use the attached worksheet, Where's My Location? - Directions, to play a game in which they plot points on a grid.

Young scholars use an on-line worksheet to experiment with patterns of tessellations in regular polygons. As students observe different shapes in the "Tessellate" Activity they complete a data table and practice making predictions for...

Graph transformations, write rules to describe transformations, find coordinates of vertices after given transformations: geometers practice these skills on a two-page worksheet in 14 problems. No answers are provided.

High schoolers "paint" with torn paper!. They focus on the placement of features, facial planes, shadows and highlights using a black and white image. The results from this lesson are visually stunning, and the materials you need to get...

Students demonstrate the Bernoulli Principle, review the influences that affected the Wright Brothers, and make and modify paper airplanes. This amazing lesson plan has an excellent structure, and very clear plans for the students to...

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

Students graph coordinate points to create a picture of Snoopy. In this coordinate point lesson plan, students read a book and learn about Rene Descartes' invention, the coordinate grid.  Students graph a surprise picture on...

In this transformations worksheet, students identify the coordinates of triangle MNO after completing three translations and one reflection. Students use the triangle MNO with given coordinates to complete each transformation on the same...

In this transformations activity, learners review the terms and example diagrams for a translation, reflection, and rotation. Students then identify the coordinates for a triangle after completing the given transformations in the four...

In this vector instructional activity, students find symmetric equations and the equation of a plane for given situations. They identify unit vectors and determine the distance between midpoints. This two-page instructional activity...

Students play a "Battleship" type of game to practice graphing on a coordinate plane. In this coordinate graphing lesson, students select a point on their grid to place their "battleship." It the opposing team misses the ship, the...

Students gain practice reading coordinates and plotting points by participating in the Coordinates! Game. They demonstrate and test their skills with graph paper and the Maze Game.

Learners explore the concept of quadrilaterals. In this quadrilaterals instructional activity, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

In this graphing functions instructional activity, students solve and complete 13 different problems that include identifying and graphing various functions. First, they graph each of the functions shown on the graphs provided. Then,...
