Design a Better Classroom Workplace
Learners design a new classroom workplace. In this architecture lesson, students use area formulas to identify the problem with the existing desks in their classroom. Learners design their own solution volume formulas to solve the...
Curated OER
The Box Problem
Students create graphic, algebraic and verbal ideas of functions. In this algebra lesson, students graph functions and identify the zeros of the functions. They find the domain and range and classify functions as relation or not.
Curated OER
A Cylinder and Its Net
Students sketch the nets for given polygons and cylinders. In this geometry lesson, students find the measurements that correspond with prisms, cones and cylinders. they identify parts of three-dimensional shapes.
Curated OER
Make a Box
Learners use specific dimensions to create a box. In this geometry lesson plan, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Cruising the Internet
Students identify the parts of an engine using a graph. In this statistics lesson, students make a graph from their collected data. They calculate the volume of a cylinder using a line of regression and a scatter plot.
Curated OER
Electrical Resistivity
Students examine how materials oppose the flow of an electrical current. In this resistivity lesson students complete several experiments on the differences between resistance and resistivity.
Curated OER
The Metric System
Students convert measurements within the metric system. In this measurement instructional activity, students explore the different units of the metric system and practice converting numbers from one unit to another.
