Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Pupils construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.

Students investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity is when...

Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane

Students examine the rhombi or diamond shape and compare it to the square. Students are challenged to create as many flat rhombus shapes as possible and develop a definition for the rhombus shape in 20 minutes while working in teams of...

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.

Students investigate the dimensions of a full-rigged ship and a schooner. Using the dimesions, they calculate and compare the area of the sails. In groups, they create model sails that require modeling and estiminating using the...

Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

Sixth graders observe the creation of a tessellation with hexagons. In groups, they work with polygons to discover what shapes can be used to create tessellations and explore the angle measurements of each shape. Using internet websites,...

Students practice descriptive writing. In this unique writing lesson, students hear a story about a mitten. Then three grade levels come together to first, create a mitten on KidPix; second, describe the designed mitten; and third, try...

Second graders create an ABAB pattern with their name. For this early elementary math lesson, 2nd graders first model their names in an ABAB pattern with unifix cubes. They then recreate the pattern using letter stamps on KidPix.

Second graders count by 5's to 100. In this math lesson conducted on the 100th day of school, 2nd graders use picture stamps in the KidPix program to count by 5's and get to 100.

First graders use manipulatives to complete and extend patterns. In this patterns lesson, 1st graders complete a pattern with a missing element, extend a pattern, and sort objects by characteristics.

In this activity, students develop algorithms for generating and generalizing patterns related to triangle and square geometric models.
