Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns.  Scholars could find the answer algebraically or create a table to analyze the...

Teach your math lovers how to solve linear equations by graphing. High schoolers identify pairs of coordinates and use it to graph a line and use the TI to graph and observe the line.

Physics stars design mobiles that demonstrate rotational equilibrium. They take measurements and solve related equations for force by graphing, substitution, or determinants. This is a well-developed lesson plan, complete with student...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

In this linear equation worksheet, students solve five systems of linear equations using the substitution method.  Three examples with steps to solve are provided.

Science equipment can be handy for math class, too. Scholars learn to solve one- and two-step linear equations by using the concept of a balance. They solve real-world problems in a variety of contexts by writing and solving linear...

In this algebra lesson, learners solve systems of equations. They solve using substitution and elimination. There are 10 questions.
