Word problems. Inequalities. Money. What? Does Marissa have enough money left in her bank account to go to the movies? One variable, two given amounts. Set up this inequality to determine how much Marissa needs to have in her bank...

Your algebra learners analyze the value of an algebraic expression to decide if it will increase, decrease, or stay the same when one variable is changed as the others stay constant. Their collaborative efforts culminate with a written...

Pencil in the resource on writing verbal phrases into your lesson plans. The 15th installment of a 36-part module has scholars write verbal phases for algebraic expressions. They complete a set of problems to solidify this skill.

Everyone seems to freeze when they see a fraction! Give your classes a lesson to watch and rewatch until they are comfortable with the process of solving rational equations. A video presenter demonstrates solving two rational equations....

For learners of algebra, this presentation could be of good use. They are coached on the basics of how to calculate square roots and perfect squares, and they are shown the intriciacies of the Pythagorean Theorem. There are many practice...

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...

This clip is great! Your budding algebra experts will have no trouble understanding what the degree in a polynomial means. The degree is compared to a mountain range, the highest peak in the range usually names the entire set of...

Learn how to factor the quadratic polynomial ax(squared)+bx+c, where (a) does not equal 1. This quick algebra lesson focuses on using the "bottoms up" method to factor this polynomial. The instructor uses an interactive whiteboard to...

Mr. Anderson explains how scientists are able to date ancient objects using radiocarbon dating. He describes carbon 14, what it is, and how it can be used to date an object. This lecture provides a very clear explanation of a slightly...

Your algebra learners will manipulate an expression's form in order to make obvious the value of it increasing, decreasing, or staying the same, when one variable is changed as the others stay constant. Your future physicists'...

Your river sportsmen will explore an example of paddling upstream as they build functions modeling speed and time in terms of the speed of the current. They then use their algebraic models to interpret features of the function related to...

Learners understand that algebra is a branch of mathematics that uses symbols or letters to represent unknown numbers in problems. They also understand the definition for an algebraic expression. Make sure to click on the Download the...

Students practice adding polynomials using algebra tiles. Students view a PowerPoint presentation in which they are introduced to the concept of modeling polynomials using a scaled down version of algebra tiles. Students walk through...

Students add and subtract polynomials. In this algebra lesson, students use algebra tiles to perform operation of polynomials. They model their problems and understand how to combine like terms using tiles.

Students assess how algebra, telescopes, space exploration and optics are so important in astronomy. They encounter studies on the Hubble Space Telescope, Hubble Deep Field and how algebra helps to determine the effects of contamination...

In this fundamental algebraic skills learning exercise, students solve 11 various problems that include various algebraic skills. First, they use the coded wheel to answer 2 questions about a message. Then, students substitute the given...

Students assess how patterns, functions and algebra can assist NASA engineers design new ways of propelling spacecrafts. They explore how electricity and magnetism are replacing the fuel-consuming rocket propulsion. Electromagnetism is...

Students solve linear equations. In this algebra lesson, students use manipulative's to see the steps taken when solving linear equations. They solve using addition, subtraction, multiplication and division.

In this algebra lesson, students work in groups to design a treasure map in which algebraic equations must be solved using the correct order of operations. Students decide where treasure is hidden, then create and follow their group's...

Students examine linear equations. In this functions and algebra lesson, students write equations in the slope-intercept form. They enter data in a graphing calculator, examine tables, and write linear equations to match the data.

In this algebraic statements worksheet, students determine whether thirty-three algebraic equations are true of false statements. A math cartoon as well as a link to the solutions is provided at the end of the worksheet.

Students write the algebraic equation to determine the number of weeks money must be saved to purchase a yo-yo. In this algebra instructional activity, students create a pattern of one penny surrounded by six pennies. They continue the...

In this variable and expression learning exercise, students differentiate between variables and expressions. They write algebraic expressions using exponents and interpret algebraic expressions into words. This one-page learning exercise...

In this algebra worksheet, students solve 6 problems in which students use the sample model to write equations. Students write the equation in words, replace the words with values from the model. and solve the equation.
