Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...

Give your scholars the support they need to work with formulas. A reference page offers definitions and picture examples of perimeter, area, surface area, volume, the Pythagorean theorem, a variety of shapes, and more. 

Use several shapes to practice finding the perimeter and area. Each page presents examples of different items, including money, the floor plan of a room, and a parking lot.

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Provide a little extra support for your emerging mathematicians with a personal word wall. Including graphics and images that support children with learning to count, identify colors and shapes, and read high frequency words,...

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

Teach children how to make a multiplication table, and they'll be multiplying for life. Following this series of steps, young mathematicians learn to use patterns and the relationships between numbers to create...

Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...

Examines special parallelograms. Students learn about a rectangle, rhombus, and square. Definitions and examples with solutions are included.

Brush up on your math skills relating to the area of rectangles then try some practice problems to test your understanding.

This fifth-grade lesson explores the area of a rectangle with fractional side lengths. We tile the rectangle with unit rectangles and show that the area is the same as would be found by multiplying the side lengths. We multiply...

MathWorld provides multiple definitions and formulas for the mathematical term, square.

This site provides definitions of different types of polygons and figures.

Learn about the properties of rectangles, rhombuses, and squares, and practice identifying them. Includes hints for questions. CCSS.Math.Content.3.G.A.1 Understand that shapes in different categories

This website has basic definitions for most polygons, regular and irregular.

A complete reference guide to quadrilaterals including squares, rectangles, parallelograms, trapezoids, and rhombus. It provides definitions and interactive activities that enhance further explanation.

Biographical summary of the life and career of Piet Mondrian, Dutch painter best known for his abstract paintings made from squares and rectangles.
