Fifth graders explore the concept of symmetry using lines drawn through different shapes. The worksheet that is included in the lesson should be used to chart the lines of symmetry for the different shapes drawn.

Sixth graders examine where mathematics came from. In this Math History lesson plan, 6th graders complete various activities to understand mathematical reasoning. Students complete critical thinking questions.

Fourth graders participate in hands-on activities to introduce them to the concept of symmetry. They make a silly symmetrical picture out of their names after gluing them onto a larger sheet of construction paper. This is a really...

Students will play a variety of learning games to explore and practice number patterns.

Encourage students to use visualization, spatial reasoning, and geometric modeling to build their own patterns or recreate one from given square arrays.

Play interactive games to determine the number patterns and sequences.

This project challenges you to figure out how to make geometric patterns with Rubik's Cube. Leaving your cube in one of these positions makes it much more tempting to pick it up and 'fix' it. See if you can determine how different...
