Classifying Quadrilaterals
Fourth and fifth graders learn to classify quadrilaterals and use more than one name for each. They follow the directions and classify three quadrilaterals. There are also activities which can be done with a partner.

Geo-Mat
Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.
Curated OER
An Introduction to Quadrilaterals
Students explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

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...

Geometry Flip Book
Young scholars investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed...

Positive Perspectives Posters
Sixth graders create a poster using one-point visual perspective. After exploring several examples of one-point perspective, 6th graders create a drawing around the theme of school community. Posters are illustrated and installed...

N Equal Parts by Construction
Middle schoolers experiment with straight edges and compasses to divide lengths into equal parts. They identify different fractions of the total length.
Curated OER
Measuring The Earth
Students use their geometry and trigonometry skills to determine the distance between their school and another school.
Curated OER
Acceleration
Students develop an understanding of velocity and to distinguish it from speed. To determine the difference between a scalar and a vector quantity. To explore how acceleration is derived from velocity and time.
