Area of Tangram Pieces
Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...
Balanced Assessment
Plenty of Pentagons
Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Balancing Act
Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry activity, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.
Curated OER
Geo Jammin'
Students compare and contrast related two- and three-dimensional shapes, and complete a Venn diagram illustrating the attributes of each. Using a poem pattern from another lesson, students use data from the diagram to write an attribute...

Shape City
Students add to a class Shape City by designing and constructing new buildings.
Curated OER
Drawing Figures
Third graders draw shapes that are congruent. In this congruency lesson plan, 3rd graders use grid paper to draw letters and figures and their congruent partners. They complete a worksheet while working in a whole class setting with the...
