Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Ninth graders investigate quadrilaterals.  In this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas.  Additionally, students create various quadrilaterals given...

Learners investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Young scholars perform an experiment to find the linear relationship between the appllied weight and the bend of the cantilever. In this linear relationships lesson, students follow detailed directions to set up an experiment. They add...

Students investigate slopes as they study topographic maps. For this algebra lesson, students discuss and apply the concept of slopes to graphing and analyzing data.

Learners explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Learners place dots on the screen to recognize that they have created Sierpinski's Triangle.

Middle schoolers discover the linear relationship between degrees Farenheit and degrees Celsius. They manually compute the slope and y-intercept of the line passing through points. They convert Celsius to Fahrenheit degrees.

Fifth graders read postcards and find their locations on maps. They use the pictures and text on the postcards to write about imaginary vacations. They compute the mileage and compare it to TripMaker data.

Students collect data on population growth. In this statistics lesson, students graph their data and make predictions. They find the linear regression and the best fit line.

Learners explore the concept of irregular fractals. In this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. Learners calculate fractal dimensions of various fractals.

Students find number patterns in the generation of several different types of fractals.

Students explore the concept of fractal patterns. In this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...

A guide to support parents as they work with their students in problem solving with the coordinate plane.

Solve all sorts of word problems with crazy contexts that use polygons on the coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This lesson focuses on the relationship between algebraic, graphical, and contextual expressions of linear equations.

Given a picture of a triangle on a coordinate grid, students are asked to find the coordinates of points which divide line segments in a given ratio. Aligns with G-GPE.B.6 and G-SRT.B.5.

Students develop and apply the distance formula and an x-y coordinate plane on a hurricane tracking map, and then use a map scale to determine distance in miles. Then, using MATLAB computer science programming language, students help...
