Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

An outstanding lesson plan on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Learners examine a chart that lists the main characteristics of polygons and 3 dimensional figures. They make examples of the polygons and figures using pretzels and gum drops showing how the gum drops are vertices and the pretzels are...

Students identify and name different geometrical shapes. In this math lesson, students distinguish odd from even numbers. They describe the properties of 2 and 3 dimensional objects.

Young scholars learn five songs to define and develop understanding of the attributes of two- and three-dimensional figures and the meaning of mathematical terms. They classify objects as either two- or three-dimensional, through the use...

Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the lesson, they use the shapes they made and...

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Students use tangrams, student literature, and Websites to explore shapes.

In this math vocabulary worksheet, students complete 15 multiple choice problems, choosing the correct definition for a set of math terms. A reference web site is included for additional activities. 

In this math vocabulary worksheet, students complete multiple choice problems where they match the correct math vocabulary word to its definition. Students complete 15 questions.

High schoolers, through investigation facilitated by dynamic geometry software, determine geometric properties and relationships involving two-dimensional shapes, and apply the results to solving problems.

In this math vocabulary worksheet, students solve the clues for math vocabulary words to fill in the blanks in a crossword. Students complete 8 problems.

In this map activity, 6th graders identify and complete 10 different problems that include various dimensional maps. First, they complete the table on the right by coloring the maps found on the bottom. Then, students determine the...

Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Use this volume of solids lesson to have learners find the surface area and volume of cylinders, pyramids, and prisms. They place cubes inside three-dimensional figures to determine the volume. Worksheets and answers are provided.

Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

Shape one's understanding of geometry using the resource. The sixth of seven chapters in 6th Grade Math focuses on geometry principles. Future mathematicians learn to find the area of parallelograms, trapezoids, triangles, and other...

Students examine problem solving techniques when working on spatial problems. They discover how models, sketches, and drawings can be used to understand on something works. They design a model of a bridge using given dimensions and...

Learners, in groups, use song lyrics and math to descrie two and three dimensional shapes.

Learners explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.

Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Second graders organize solids into categories, depending upon whether they will roll, slide or do both on a home made ramp. Students describe and compare attributes of three-dimensional geometric solids.
