Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...

How many of 2-D or plane shapes can your class identify? Can they get them all? Little learners view and review the names of nine different shapes, such as rectangle, square, triangle, and circle, to name a few.

Where this lesson idea is lacking in materials, it makes up for with creativity! Using "Goldilocks and the Three Bears" as the background, mathematicians plot points on a coordinate grid to create props for the story. The polygons all...

Students 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...

Can your class calculate the area of a regular quadrilateral? They can now, with this handy presentation which provides an explanation, the formula, and examples of finding the area of a regular 2-D shape. 

What is the difference between a star and a triangle? Its attributes of course. Discuss the basic shapes with your class, then have them practice identifying shapes by circling the one in each row that is different. 

Fourth graders have a class discussion about fraction and negative numbers that were in the coordinates. They plot and read ordered numbered pairs. They transform ordered pairs and explore transformation of figures on a plane.

Get those kids to solve and graph 10 different problems that include various types of functions and their relations. They determine if each graph represented is the relation of a function then determine which value of the variable will...

Which shapes are considered quadrilaterals? View and learn that two dimensional shapes with four straight sides are considered quadrilateral. The rhombus, parallelogram, rectangle, and trapezium are only few of the fabulous shapes...

I remember doing this activity when I was little. Learners color each shape the color indicated at the top of the page. Squares are blue, cubes are red, circles are green and so on. There are 30 shapes to identify and color. 

Introduce the names and properties of basic 2-D shapes. Images and defining features of the circle, rectangle, triangle, and square are shown. Each image is colorful and includes a happy, smiling face, perfect for younger learners.

Some of the most important vocabulary in the study of geometry is presented here. In this PowerPoint, learners view the definitions for points, lines, segments, and rays. The definitions and graphics are clear, and kids are also coached...

Lesson 20 is part of a 22 lesson unit on boat safety and water sports. The focus in this lesson is getting up on the wake board. If you click on the resource link at the bottom of the page, there is another resource link that goes to the...

Use this series of activities to introduce learners to graphing functions. They graph both linear and quadratic equations by hand and with a Graph Sketcher Tool. Several imbedded links and handouts are included in the lesson.

In this graphing activity, 5th graders identify and graph 20 different problems on the 3 different graphs shown on the sheet. First, they use the tally of callers organized by the school to complete the three different types of graphs....

Explore rational functions with this packet. A lot of information is provided, including several examples. Learners graph rational functions and find vertical, horizontal, and oblique asymptotes. This seven-page worksheet contains...

In this perimeter and area worksheet, students find the perimeter and area of polygons. They use the proper formula to find the perimeter and area of circles, parallelograms, triangles, and rectangles. Students complete solve ten problems.

In this integers worksheet, 7th graders solve 10 different problems that include various types of integers and graphs. First, they determine the sum of 3 consecutive integers. Then, students find the ratio between 2 areas of similar...

An upper-level treatment of what is often presented as a basic concept (the right angle of an inscribed circle on the diameter), this activity really elevates the mathematical thought of the learner! Expected to develop formulas...

Student complete worksheet using the definitions of lines and angle vocabulary. They define the word and follow a direction given on the worksheet such "construct a line." They complete an online tutorial on how to measure angles using a...

In this ratios worksheet, 11th graders solve and complete 8 various types of problems. First, they read each problems and draw a sketch for each. Then, students write a trigonometric ratio for each problem and round any decimal answers...

In this comprehension check worksheet, students define 13 vocabulary words, define 5 literary terms, and respond to 23 short answer questions pertaining to chapter 1 of The Lord of the Flies in order to help them better understand the...

Young scholars engage in a study of science and mathematics with the practice of creating graphs. A guest speaker comes to the class to share statistics from the community and the students are shown how he uses the coordinate system in...

Students explore the concept of tessellations. In this tessellations instructional activity, students use an applet to construct tessellations. Students use regular polygons to construct tessellations. Students find patterns and symmetry...
