Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

Can your first graders identify a cone? What about a cube? Or a prism? Help them find the differences between these shapes with this activity, which provides a word bank for three-dimensional shapes. For extra practice, bring in examples...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Help your students identify the attributes of two-dimensional shapes. They read the book Round is a Mooncake, and use pattern blocks to sort shapes. Students sort shapes according to their attributes.

Sew up pupil interest with an engaging, hands-on instructional activity. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses...

Assess scholars' knowledge with a 22-page assessment that covers place value, patterns, probability, estimation, measurement, geometric figures; and their ability to add, subtract, multiply and divide proficiently. 

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Extend scholars' learning experience with a unit consisting of five shape lesson plans, an extension activity, assessment, and rubric. Begin by reading a story about shapes, then conduct an overview and assign pupils' their first...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...

Students make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

It is really important for learners to know when objects are the same and when they are different. Here are five rows of objects, they circle the objects in each row that are the same or different from the first object in that row. 

Young scholars identify 3-D geometric shapes through different pieces of artwork. They examine and identify segments and angles. Students act out shapes and create a piece of artwork. Additional cross curriculum activities are listed.

How do you teach kindergartners to count? Use this scripted explanation to show pupils how to solve problems that ask them to determine whether the number of objects in one group is greater than, less than, or equal to the number of...

Sixth graders develop a rule for finding the volume of rectangular solids using colored cubes. They investigate the properties of solid figures and find the volume of an object by counting units. Students fill spaces with standard-sized...

Young visual learners explore different cross sections of 3-dimensional objects. First, cross sections of cubes are explored by using an interactive flash activity. This is then extended by looking at cross sections of spheres,...

Which water creature is the biggest? Youngsters look at an image of a big shell, then draw a bigger shell next to it. They do the same for a big fish. Next, learners practice with the superlative as they circle the biggest duck and frog....

Learners investigate the connection that exists between Algebra and Geometry. They classify two and three-dimensional figures. Pupils use formulas to solve problems in geometry and use appropriate measuring devices in the right contexts.

Kindergarteners explore various representations and uses of numbers to develop number sense. They participate in an activity and arrange patterns into groups. Students compare the sets and describe the objects in each set.

First graders demonstrate their ability to compare the lengths of three objects and determine which is the longest or shortest. Pupils match the correct answer to each of the seven story problems.  All lengths are expressed in...

In this math activity, students write down the equation of a plane. Then they create the equation of a line. They also define the lines that are perpendicular.
