If your math students are having a hard time with graphing and slopes, this video could be a great resource as they prepare for the SAT. Sal takes care in explaining his thought process, making sure where to note different strategies to...

Sal picks up the pace in this video, going through problems 1-7 on page 774 of The Official SAT Study Guide. Basic algebra, arithmetic, and geometry problems start out this section, allowing students to build up some steam before hitting...

Clarifying that speed matters more than rigor on the SAT, Sal takes care to show students the most efficient and easiest ways to solve various math problems. Those who get stuck on certain types of problems would benefit from his...

Continuing his SAT review session, Sal explores problems with slopes, linear equations, and congruent angles. He begins problem 10 (geometry) but finishes the problem in the next video.

Danny the penguin represents a constant and snow represents variables. This clip is wonderful for learners just starting to understand algebra. It is clear, provides concrete examples, and is totally cute. A great idea for expressing...

Learners explore equations with constants, variables and with exponents. They identify and define variables, constants, exponents, expressions, and equations, as well as give an example of each. Your class will also draw their...

A great start to activate thinking about the scientific method, instruments, measurements, accuracy, constants and laws. Each slide describes important procedures and examples essential for the study of science.

In this math worksheet, learners find the solutions to the problems that apply the time-independent Schrödinger equation. They examine the relationship between the mass and energy.

In this experimental design activity, students are given a full comprehensive outline for designing an experiment. There are checklists included for each section of the experiment for students to use as a guide for properly completing an...

In this experimental design worksheet, students evaluate experiments using a design checklist. They suggest ways to improve the experiments and they identify all the components of the design.

In this symbols worksheet, students read about how different symbols are used to represent variables or constants in equations. Then students complete 3 problems.

In this math worksheet, students examine the two springs with spring constants k1 and k2 are attached to a block of mass m. They show the frequency of the oscillations on the frictionless surface.

For this chemistry worksheet, students examine the concept of thermodynamic equilibrium constants with intense detail. The application of the knowledge is practiced with problem solving.

In this weather experiment worksheet, students design an experiment that allow them to experiment a phenomenon of weather. Students identify the independent and dependent variable for their experiment. Students list the procedures as...

In this math worksheet, students practice using the constant feature of the calculator by performing an operation several times with the same decimal value but starting with different values.

For this math worksheet, learners practice using the constant feature of the calculator by performing an operation several times with the same integer value but starting with different values.

In this math worksheet, students solve the problems using the single integer constants by practicing on the calculator. The sheet is a teacher's guide.
