Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.

Fourth graders measure cups, quarts, and liters.

Learners observe the cracks in school walls and pavements. In this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the lesson.

First graders study the months of the year. They enjoy making a class book using their birthdays and the types of weather in that month. After a lecture/demo, 1st graders utilize a worksheet imbedded in this plan to design their book.

First graders work in pairs to create a class big book for months of the year. They work together to create a detailed version of their month that includes any special holidays and activities.

Fifth graders use the Celsius and Fahrenheit thermometers to compare temperature readings. They use the Internet to find the temperatures of selected cities. After data is collected for five days, 5th graders graph the temperatures.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane

Fourth graders use drawing and paint tools to identify, draw and state several geometric terms.

Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

Sixth graders observe the creation of a tessellation with hexagons. In groups, they work with polygons to discover what shapes can be used to create tessellations and explore the angle measurements of each shape. Using internet websites,...

Sixth graders, in groups, explain why they think something. This requires students to listen to and respond to each other. In this particular lesson, 6th graders explain to their classmates when one can or cannot construct a specific...

Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...

Sixth graders discuss the characteristics of specific angles and then use the information to to identify and estimate given angles. The class goes outside, identifies north, and turns a specified amount of degrees. Using a given compass,...

Fourth graders select the Quadrilateral Quest game, they find all quadrilaterals with the given properties. They are told that the word congruent in this game means equal. Students are given two to four properties of quadrilaterals. ...

Fourth graders, using a straight edge, determine whether a point is inside or outside of a given figure. With worksheets, 4th graders practice analyzing geometric relationships such as parallel to, perpendicular to, etc.

Sixth graders determine the number of triangles in the Star of David.

Fifth graders explore a plotting on a coordinate plane. Using a specified website, they play a "Maze Game" where they navigate a robot through a minefield. As students work through the problems, the rigor of the problems increase. ...

High schoolers explore the concept of fractals. In this fractals activity, students discuss Sierpinski's Triangle using an applet. High schoolers discuss the patterns involved with fractals. Students discuss the area of Sierpinski's...

Learners chart temperatures in Egypt on spreadsheet to determine how weather conditions affect lifestyles.

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.
