Equation Solver
Solve your equation and prove it, too. Young mathematicians solve linear equations using an interactive. They must input a property to justify each step of their solutions.
Curated OER
Linear Systems
Students solve and graph linear equations. In this algebra lesson plan, students solve systems of equations using elimination and substitution. They graph their answer and identify the point of intersection.

A Solution for Precipitation
Students predict the product of chemical reaction using the solubility rules. In this chemistry lesson, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Fractions and Ribbons
Sixth graders explore using inverse operations to solve decimal and fraction problems. In this decimal and fraction lesson, 6th graders prepare ribbon for a part and need to cut it in equal lengths. Students analyze the problem.
