Identifying Shapes
For this shapes worksheet, students identify shapes, including triangles, squares, rectangles and circles. A reference web site is given for additional activities.
Curated OER
Triangles Introduction
Students explore geometry by drawing various shapes in class. In this triangle characteristics lesson, students identify the attributes that classify a shape as a triangle and practice using their bodies to create triangles in class....

Shape Lessons That Connect
Shape lessons provide a way for students to learn about art, science, and math.
Curated OER
Classifying Polygons
Students study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.
Curated OER
Symmetry that is Basic and Beautiful
Students explore lines of symmetry. In this symmetry lesson, students divide and combine shapes along basic lines of symmetry. Students explore symmetry in real life objects.
Curated OER
Complete the Patterns
In this patterns worksheet, learners analyze the geometric shapes in each of 5 rows. Students determine the pattern and then draw the next three shapes that would continue the sequence.
Curated OER
Complete the Patterns
In this patterns worksheet, students analyze a row of geometric shapes in a pattern. Students draw the next three shapes that would come in the sequence. There are 5 problems.

Geometry Maze and Coloring Sheet
In this geometry coloring maze learning exercise, 3rd graders color a path of rectangles to help a dog ( pictured) to find his way to the dog house. They choose the rectangles out of other geometric shapes such as stars, oval, triangles,...
Curated OER
Symmetrical Measurements of The Body
Third graders find symmetry in their body. In this symmetry lesson, 3rd graders look at different geometric shapes and identify which ones are symmetrical and find their line of symmetry. They measure body parts to the nearest half inch...

Cubism
If cubism were a religion, would you follow it? Lower-level tasks focus primarily on counting the number cubes in a structure and relating the number to surface area. As learners progress to higher-level tasks, isometric drawings and...

Guess My Piece -working with Legos
Learners participate in guessing their partners' hidden Lego pieces from their verbal clues. They work in partners to accomplish their goals. They are meeting a variety of math standards by completing this lesson.
Curated OER
Draw It!
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...
Curated OER
Perimeter - calculate in units
In this perimeter worksheet, students calculate the perimeter by the number of units each shape is showing. Students calculate the perimeter of 4 shapes.
Curated OER
Copy Cat
Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
Curated OER
Finding Coordinates on a Grid
In this finding coordinates on a grid worksheet, 3rd graders write the name of the shape that corresponds to eight given coordinates.
Curated OER
Regular or Irregular Polygons
In this polygons activity, students decide whether each shape is a regular polygon or an irregular polygon. Students complete 6 problems.
Curated OER
ARE YOU A TRIANGULATEER?
Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...
Curated OER
Rep Tiles
Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
Curated OER
Tangram Geometry
Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.
Math Mammoth
Scales Problems
In this scales worksheet, students use addition, multiplication, and division to find out how much the shapes on the scales weigh. Students complete 8 problems total.
Curated OER
Area And Perimeter Using Pentominoes
Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...
K6 Math
Area - Square and Rectangles
After third and fourth graders understand how to find the area of squares and rectangles, give them this sheet for practice. There are three squares and three rectangles included here, but there isn't a ton of workspace.
Curated OER
Perimeter
Learners study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of...
