Geometry and Shapes
Fourth graders are asked to name different shapes.Four to five students to share their answers with the class. The teacher leads the discussion in geometry about the properties associated with shapes.
Curated OER
Pattern Block Polygons
Sixth graders create polygons. In this shapes lesson, 6th graders explore prefixes such as oct, tri, quad, pent, etc. and share their findings. Students use pattern blocks to create two different polygons and label them.
Curated OER
Magical Shapes
First graders practice manipulating shapes into different locations. They see that even though shapes may look different when they are moved into different locations, the shape remains the same with the same properties. They make...
Curated OER
Tessellations
Seventh graders investigate geometric shapes using tessellations. In this geometry lesson, 7th graders practice tessellations using different shapes. They create different designs using tessellations.
Curated OER
Origami Cube
Students compare two lengths using the area of a square. In this geometry instructional activity, students solve problems using ratio and proportion of the two shapes. They solve equations by taking the square root of both sides.
Curated OER
Shapes!
Students identify five basic geometric shapes by naming them according to their defining characteristics. They draw the shapes and identify food with similar shapes.
Curated OER
Platonic Solids
Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.
Curated OER
Trigonometric Ratios
Young scholars measure and analyze angles. In this trigonometry instructional activity, students measure angles and distances use non-traditional techniques. They identify the different ratios of sine, cosine and tangent.
