Turn your classroom into a local cell phone store. Then, have your cell phone agents use linear equations to visually display three cell plans and their advantages. It makes for a great group project. Discuss how to decide which plan is...

Teaching linear function relationships using contextual information is beneficial to pupils' understanding. The lesson uses problem solving to build linear functions given different information for each problem. This is the second...

Take a look at linear functions in a new environment. A three-stage algebra project first asks learners to model the salt concentration of an aquarium using linear functions. Then, using iterations, pupils create a set of input-output...

Two of the strategies for solving systems of linear equations are represented in this foldable: substitution and elimination. Learners solve three examples of each. 

Learners use the on-line affine recurrence plotter to graph equations. They work on-line to create graphs of trout in a trout pond and savings account balances when interest is compounded over time. Links to the four one-day lessons are...

An equation is an equation is an equation. Scholars see there are many ways to solve them when they first sort a set of linear equations as written in standard form, point-slope form, or slope-intercept. They then write equations in all...

Learning to break apart numbers into smaller pairs is a critical step young mathematicians take as they develop their number sense. To practice this skill, children are provided with sets of three numbers and are asked to pick the two...

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take part...

0/0 doesn't equal 0! Begin this lesson by allowing the class to explore the concept of dividing by zero. The introduction allows for discovery and provides meaningful examples of dividing by zero. This understanding leads to solving...

Represent ratios using a variety of methods. Classmates combine the representations of ratios previously learned with the coordinate plane. Using ratio tables, equations, double number lines, and ordered pairs to represent...

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

Test your class with a physical science quiz. Learners explain chemical processes, name compounds, write formulas for chemical compounds, balance equations, and more. 

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

Here is a TI-Navigator™ activity that allows students to review the concept of factoring and solving quadratic binomials, including a connection to graphical solutions. They enter a number such as -2 using the minus key and not the...

Young mathematicians view a video on solving quadratic equations by factoring. They use this skill to complete a worksheet of practice problems — a great way to gauge understanding!

The worksheet is great but the answer key is fantastic! This practice test focuses on quadratics and polynomials. Learners are expected to be able to simplify and factor expressions and solve equations. The best part is the answer key...

Fifth graders take a look at how to solve equations where parentheses are present. There are addition, subtraction, and multiplication problems included. Learners practice solving 22 problems altogether, and there is an answer key...

In this multi-step equations worksheet, 9th graders solve and complete twenty-four different problems that include using a graphing calculator to complete. First, they solve for x in the first section. Then, students solve using the same...

In this Algebra I/Algebra II instructional activity, students solve equations with variables on both sides of the equal sign.  Problems include the use of the distributive property to remove parenthesis.  Thetwo page...

In this equation basics worksheet, students solve simple algebraic equations. This one-page self-checking worksheet may be completed on-line. If preferred, an answer sheet may be printed.

Learners differentiate between expression and equation by evaluating integers and observing the difference. They use the TI to see the steps to solve problems.

Young scholars compose equations and inequalities whose solutions are the integers 1-31 and utilize them to number one month of a calendar. They take notes on two ways to work backwards from a solution: by using the number and by setting...

In this equations worksheet, students solve one step equations by using one of the four operations. The pages are organized so the addition/subtraction problems are on one page and the multiplication/division problems are on the second...

For this equations and mental math practice worksheet, learners sharpen their problem solving skills as they solve 6 story problems.
