Variables and Expressions
High schoolers solve equations by writing expressions. In this algebra lesson, students identify the different values for each variable. They use the navigator to see how to solve equations.
Curated OER
Perimeter Pattern
High schoolers investigate perimeter patterns formed by a hexagon and a triangle. They will identify the dependent and independent variable and write a function for the relationship.
Curated OER
Point Graphs
Pupils experiment with point graphs. For this math lesson, students are divided into groups and perform an experiment to see how high a ball bounces, recording their results on a point graph. Pupils then answer provided questions.
Curated OER
Rules of the Roll
Middle schoolers roll a ball down a plank and measure the distance it travels. Students graph the distances the ball travels as they change the height of the incline (increase slope).
Curated OER
Evaluation Expressions
High schoolers explore algebraic expressions in this Algebra I lesson plan. They evaluate expressions using paper and pencil and then use the TI-83 to provide immediate reinforcements.

Developing an Investigation
Watch as your class makes the transition from pupils to researchers! A well-designed lesson has scholars pick a solar wind characteristic to research. They then collect and analyze official data from the LANL website. This is the...
Curated OER
The Solar Cycle
Students research the solar cycle. In this Science lesson, students use the internet to investigate the solar cycle. Students produce a spreadsheet and graph from the information collected.
Curated OER
Volumes of Rectangular Prisms
Students determine the volume of a rectangular prism. They then maximize and minimize the volume given variable side lengths. Finally, they factor the volume equation to determine the side lengths.
Curated OER
Compound Interest
Pupils analyze the variables in the formula of a compound interest. They model the increase or decrease of an investment using compound interest and discuss different compounding periods.
