The process of elimination really works! Use elimination when substitution isn't doing the job. The 29th segment in a series of 33 introduces the elimination method to solving linear systems. Pupils work several exercises to grasp the...

In this simultaneous equation worksheet, students use the process of elimination and matrices. This one-page worksheet contains six problems.

Students, using algebraic operations, solve and check linear equations. At the beginning of class, they write a paragraph comparing the solving of math problems to solving real life problems. Students observe solving systems of two...

Do you want your budding mathematicians to be able to explain 'why' and not just 'do'? This lesson encourages an understanding of the process of elimination. Pupils are expected to understand how and why the elimination method is a valid...

Now that learners figured out how to solve for one variable, why not add another? The lesson demonstrates, through examples, how to solve a linear system using graphing, substitution, and elimination.

Students solve multi-step equations and apply the process of elimination. In this algebra lesson, students solve linear inequalities and equations using linear combination and evaluation. They graph their results on a number line...

Can two lines intersect at more than one point? Using yarn, create two lines on the floor of the classroom to find out. Cooperative groups work through the process of solving systems of equations using task cards and three different...

Students assign value to different shapes of pattern blocks, and estimate values and use process of elimination to determine values. In this pattern block values lesson plan, students trace each block on a worksheet and use 5 blocks to...

Can you solve an equation graphically? Absolutely! This Algebra II lesson plan makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process...

Learners explore the concept of solving systems of equations with two equations and two unknowns. In this solving systems of equations lesson, they work through problems of solving systems by substitution, elimination, and graphing....

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Students complete a Sudoku puzzle using their math skills. After listening to the rules of Sudoku and observing a demonstration, students use the process of elimination and other methods to complete puzzles. They explore how the...

Students solve a system of two unknowns.  In the Algebra instructional activity, students use a on line computer applet/program to solve a system by the elimination method.  The student's work is self checking, giving immediate...

Ever played 20 Questions? A similar game helps young learners practice asking and answering yes-or-no questions. Spread out several objects, preferably all similar with slight variations (buttons or coins would work well). A leader...

Physical or life science learners measure the amounts of water eliminated by intestines and the urinary system, and the amounts lost via respiration and perspiration. In doing so, they discover that the body's water must be replenished...

Students construct and maintain a school garden. In this gardening lesson, students plan the construction of the garden by writing letters to local businesses asking for supplies and materials; students build the garden using their math...

Tenth graders investigate the Elimination Method in the solving of equations. They solve the equation using this method in examples with the teacher and then transfer the new knowledge to independent practice.
