(Use graph paper, if available.) Next, she has students draw a minimum of six polygons on the grid, making sure the shapes don’t overlap. To review polygons, Runde has students draw a grid on a sheet of paper, first in pencil, then in marker. What to Do: Jennifer Runde, a fifth- and sixth-grade teacher at Echo Bay Central Public School in Ontario, integrates art into her geometry lessons. What You Need: Paper, pencils, rulers, markers “We combine groups and elastics to show terms like intersecting, parallel, and perpendicular,” Hall says. For example, she might ask students to create a shape with only one set of parallel sides or a shape with four right angles that is not a square.

“I call out geometry terms, and the groups create the shape or term,” Hall explains. (One package of elastic typically makes one jump rope.) Students She gives each group sewing elastic knotted into Chinese jump ropes. To review polygons and geometry terms, she breaks students into groups of five or six. What to Do: Fifth-grade teacher Kelly Hall incorporates kinesthetic activities into her geometry lessons at Whitcomb School in Marlborough, Massachusetts. What You Need: Sewing elastic or Chinese jump ropes For an added challenge, students can create images with multiple lines of symmetry. They make an object without the ruler and later prove the line of symmetry by placing a ruler on top of the blocks. Whitehair uses the activity with on-level students as well. She tasks students with making a symmetrical image with the blocks. To explain symmetry in a concrete manner to her special education students, Whitehair gives each one pattern blocks and a ruler to act as a line of symmetry. “I try to utilize the CRA model as much as possible when introducing and practicing concepts,” says the fourth-grade teacher from Garfield Elementary in Abilene, Kansas. What to Do: Christy Whitehair uses manipulatives to explore the concept of symmetry.
