What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project...

An excellent resource for a geometry class, as well as for an electrical engineering course. A thorough reference sheet covers geometric shapes such as triangles, parallelograms, and circles, as well as 3-D shapes and the Pythagorean...

This app provides young learners with opportunities to be creative while they work with different colors, letters, numbers, and shapes. 

Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...

Apply area concepts to help farmers and settle county disputes. Scholars use a given diagram and information about an insecticide spraying campaign to determine the monetary benefit to farmers. They then decide which of two counties has...

Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. In this similarity lesson, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

Learners build sled kites. in this kite building lesson, students must read directions for kite building and enlarge the proportions of the given kite pattern. Learners focus on the angles and line of symmetry in their kite. 

Here is a activity that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

Learners demonstrate the process of creating a scaled rubber band enlargement of a simple drawing. They observe and discuss a teacher-led demonstration, and create a scaled rubber band enlargement of simple drawings and their invention...

Fourth graders create enlarged replica of a stegosaurus drawing, using a grid to practice coordinates.

In this math instructional activity, 4th graders will practice converting integer values to and from words. The teacher can select either or both directions. Additionally, the teacher can select the highest place value that is used in...

Students explore graphs.  In this graphing math lesson, students record the birthdays of each classmate on a data table.  Students cut out and add a picture of a birthday cake to a floor or wall pictograph representing the...

Students practice their mathematics and mapping skills using examples from honey bee biology. Discuss why the colonies were found in this pattern. They examine food and water in the area, and how many humans live in the area where...

Create larger-than-life insects for the classroom. Bugs are usually pretty small, but during the Jurassic period they were huge. Kids use diagramming and scale conversion to enlarge a modern day insect so that it is as big as its ancient...

In this geometry worksheet, 10th graders measure different nets to figure out the shape they represent. They enlarge the nets, cut them out and create the shape to get their final answer. There are 10 nets with an answer key.

Pupils determine scale factors from one figure to another and the scale factor in the reverse direction. Scholars compute the percent changes between three figures. 

Transformations are more than the process in which sports cars become fighting robots. Listed in terms of which transformations give congruent or similar figures, several resources provide definitions and examples of the four...

Students make multiplication squares. In this math lesson, students review their multiplication facts and multiplication strategies. Students are introduced to multiplication squares when multiplying a number by itself.

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Working with thermometers, sixth graders compare the value of positive and negative numbers. Plenty of teacher suggestions and independent practice ideas are presented. This website links to two more parts in this first of three integer...

Learners consider a set of questions to determine a series of transformations that will move one figure to another. Once the series is determined, the pupil then determines whether the pre-image and image are either congruent...
