In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle. This lesson features three investigations, in which learners make tessellations by translating, rotating, and reflecting the patterns.

In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180 and 360 degrees. Learners discover there is a pattern to the sum of the interior angles of any polygon.

Did you know that you would be a different age if you lived on Mars? It's true! In this activity, you'll learn about the different rotation and revolution periods of each of the planets and calculate your age respectively. Included is an astronomy history lesson and explanation of Kepler's Laws of Orbital Motion. The activity has a calculator built into the web page, but the activity can be made more math intensive by using the given data to calculate the learner's age by hand.
