Point Comparisons
Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...
Illustrative Mathematics
Similar Triangles
Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...
Curated OER
An Uncomfortable Situation
If shapes have the same area, do they always have the same perimeter? Learners explore the relationship between the area of square units and their perimeters in a hands-on activity. Observations are recorded, and they begin to recognize...
Curated OER
Following Instructions
Get scholars thinking about the scientific process with this fun experiment they can do at home. Learners practice reading directions as they underline each instruction in a procedural paragraph. They create a flow chart and record...
Curated OER
Math On Your Lap Quilt
Get creative juices flowing when you allow groups to figure out a procedure for how to find the area of squares and rectangles. They may use the individual patchwork blocks, or they may design one using the Design Template.

Transformation
Third graders investigate symmetry by reflecting objects in different angles. In this geometrical transformation lesson, 3rd graders define the terms translation, rotation and reflection in order to physically turn geometric...
Curated OER
Shape and Space: Symmetry
Students discuss and work with lines of symmetry. In this symmetry activity, students start with a warm up activity on metric conversion. They talk about the definition of symmetry and reflection before completing a worksheet.
