Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.

Students are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...

Sixth graders identify the x and y axes in a coordinate plane and identifies the coordinates of a given point in the first quadrant. They plot specific points in the first quadrant of the Cartesian coordinate system.

Students use tangrams, student literature, and Websites to explore shapes.
