Soda Bottle Magnetometer
Introduce learners to set of complete instructions that describe how to build a magnetometer that works just like the ones professional photographers use to predict auroras. The diagrams are wonderfully descriptive, and the written...
Illustrative Mathematics
Satellite
Learners practice relating rules of trigonometry and properties of circles. With a few simplifying assumptions such as a perfectly round earth, young mathematicians calculate the lengths of various paths between satellite and...

Visual Patterns in Tessellations
Learners explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Learners examine tessellations by creating their own tessellations and completing the included worksheet.
Curated OER
Patchwork Math
Students recognize and identify shapes in their environment. They investigate why objects can be composed of several different shapes. They follow a pattern to recreate designs using various shapes.
Curated OER
Drawing Lines of Symmetry
Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.
Curated OER
Perimeter
Students examine the concept of perimeter. Students calculate the perimeter of a random shape on a grid. Students develop a better understanding of the concept of perimeter. Students calculate the perimeter of shapes.
Curated OER
Length, Perimeter, and Area
Students explore the concepts of length, perimeter and area. Students develop an understanding of length, perimeter, and area. Students calculate the area and perimeter of random shapes and calculate the area and perimeter of a triangle...

Describing Patterns
Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.
Curated OER
Points of Intersection
Students solve systems of equations. In this solving systems of equations lesson, students look for the intersection of the two lines in the system. Students solve systems that have one solution, no solution, and infinite...

The Long and Short of It - Geometry
First graders use appropriate vocabulary to compare the measurement of the animal he/she is drawing.
Curated OER
Geometry - Measurement
Students review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.
