Translations, reflections, rotations: This lesson will allow students to explore translations, reflections, and rotations using a resource of Shodor Education Foundation, Inc. Permission has been granted for the use of the materials as part of the workshop Interactivate Your Math Students. Students explore the world of translations, reflections, and rotations in the Cartesian coordinate system by transforming squares, triangles and parallelograms. Parameters: Shape, x or y translation, x or y reflection, angle of rotation. (Italics are a direct quote from Shodor.org.); Format: lesson plan (grade 6–8 Mathematics); By Deborah Bourne.

Reflection designs: Students will be able to illustrate the geometric transformation of a reflection through creating their own unique designs.; Format: lesson plan (grade 4 Mathematics); By Karen Boles.

Flipping around pentominoes: The students will use Unifix cubes to create the twelve different pentominoes. The students will join 5 Unifix cubes to make different shapes that will lie flat on a table or level surface. The students will then test for new shapes by flipping, sliding, or turning to create each different pentomino.; Format: lesson plan (grade 4 Mathematics); By Dianne Wingate.

Primary fitness skills unit: The main focus of this unit is primary physical fitness skills assessment and development. With PE class scheduled once a week, fitness assessment becomes a challenge. This unit keeps students moving and at the same time assesses their primary fitness skills in each lesson.; Format: lesson plan (grade 4–5 Healthful Living); By Bozena Mielczak.
