Triangle Side Lengths and Angles Measures
Learners identify missing sides and angles. In this geometry lesson, students use triangular theorems to identify the missing sides. They use the Pythagorean Theorem to find the different ratios of each side.

Draw It!
Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Shape and Space: Symmetry
Students discuss and work with lines of symmetry. In this symmetry lesson, students start with a warm up activity on metric conversion. They talk about the definition of symmetry and reflection before completing a worksheet.

Fractions of a Set
Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...
Curated OER
Houses
Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Unit Perimeters and Areas
Learners use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson plan, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are...
