Balanced Equations

Using the proportional relationship between objects on a scale and the concepts of equity and equality, learners analyze, write, and balance algebra equations. Balanced scales help the learners explore the abstract concepts involved in...

Review the differences among equations, expressions, and inequalities. Demonstrate with a scale how an equation balances out on both sides, and how an inequality has a set of solutions. Present a few real-world problems for your...

Help young mathematicians crack the code of word problems with this three-lesson series on problem solving. Walking students step-by-step through the process of identifying key information, creating algebraic equations, and finally...

Classmates solve 18 different problems that are mostly word problems that apply algebraic expressions. They draw different combinations of masses on a scale that would balance. They also simplify expressions and solve for x in a number...

Use tables, graphs, and substitution to solve systems of linear equations. An envelope of sample problems is passed around the classroom, and each learner has the opportunity to solve the system in the envelope. This is a great way to...

Don't rush into algebra, let learners visualize, guess, and predict their way to a successful math career. The introductory unit incorporates beginner algebraic concepts with shapes instead of variables. Young mathematicians use a...

If you have two bags with an unknown number of tiles, represented by x, and you add three tiles to get seven total, you can set up a linear equation to represent the problem. Use this example and a few others to demonstrate how to solve...

Learners solve linear equations. By observing the graph of each side of an equation using the TI-nspire graphing calculator, your class gains insight into solutions, as well as balancing equations and transforming linear equations....

Linear equations, coordinate planes, and systems of equations are covered in this extremely well-organized lesson. Composed of a series of mini-lessons, the instruction aims at explaining a different facet of solving systems of linear...

If Rylee buys a shirt and a pair of jeans with 90 dollars and the shirt costs 22 dollars, how much do the jeans cost? How many solutions does this question have? Use the video to help your learners answer these questions by modeling an...
