Geometry House!
Fourth graders use computer drawing tools to create a house of geometric shapes.
Curated OER
Lines, Rays, and Angles
Third graders read "Pigs on the Ball" by Amy Axelrod and discuss the geometry concepts presented in the book. They use Twizzler sticks and pipe cleaners to represent lines, rays and angles.
Curated OER
Lines and Angles
Students explore Geometry with Twizzlers Candy, pipe cleaners, paper, pencils, and protractors. They manipulate these items to create different angles introduced by the teacher.
Curated OER
Graphing Coordinates
Sixth graders practice graphing coordinates. In this geometry lesson, they use the x and y axis to locate points that must be connected in the right sequence to form a straight line.
Curated OER
Math Quilts
Students examine geometric shapes. In this geometric shape lesson plan, students examine how geometric shapes flip, turn, and slide to create a pattern. Students analyze the role that quilts played in helping slaves escape to freedom. ...

Measuring and Predicting Capacity
Students investigate geometric shapes through volume and dimensions. In this geometry instructional activity, students measure, weigh, and calculate sizes and volume based on estimation and calculation. They review important vocabulary...
Curated OER
Tangrams
Fifth graders explore the context of how and when to use tangrams in geometry. They create and draw a number of different geometric figures using tangrams. Students work on their visual spatial skills.
Curated OER
Visualizing Multiplication
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...
Curated OER
Exploring Area
Fifth graders explore the concept of area using the geometry of selected objects. The laboratory for this experience is the classroom. The lesson focuses upon the objects that have four sides like squares and rectangles.
Curated OER
Can You Name That Shape?
Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...
Curated OER
Operation Spaghetti
Find the math in recipes. Young chefs will follow a recipe and investigate the total cost for materials. They measure amounts of food necessary for the recipe and compute the per person cost.
Curated OER
Can You Build It?
Pupils investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The activity is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the plane...

The Sum of the Interior Angles of a Polygon
Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this lesson.
Curated OER
Geoboard Squares
Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...

All A-buzz About Math
Second graders participate in Math-Eze activities to comprehend word problems. In this word problem lesson, 2nd graders recognize why a hexagon is the best shape for a beehive. Students calculate how far bees must travel to find 2 lbs....
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...

Traveling aroud Our Town
Young scholars are asked to describe to a partner how he or she walks to school or the bus stop. They are shown on the overhead an one-inch grid paper, and at the intersection of two lines on the grid paper, students are shown a house...
Curated OER
Find the Shape
Students identify points on the coordinate plane using ordered pairs and also plot the ordered pairs on the coordinate plane. They also use properties of shapes to identify polygons such as triangles and quadrilaterals
(square,...
