Review of Hands-On Equations®

logo Hands-On Equations is a supplementary program that teaches students to solve linear equations using a balance scale and physical "pawns" and number cubes. It is basically a program using a physical manipulative for modeling and solving linear equations—great for kinesthetic and visual learners.

Before this review, I had heard about it, and I knew it involved solving equations with a balance, as if "playing." However, once I saw the complete program, I was impressed—because the system of Hands-On Equations includes not only simple equations, but also the usage of distributive property (level I), negative unknowns (level II), negative numbers (level III), AND even word problems similar to typical word problems in pre-algebra or algebra 1.

So it is much more than just a system of modeling the simplest equations. In the end of level III, students are solving equations such as 2(−x + 6) − (−2) = 3x + 1! However, the system is beneficial EVEN if your child/student gets to only do level I, which consists of only 7 lessons, because in the end of Level I, students already solve equations such as 2(x + 1) + 5 = 3x + 6.

balance, pawns, and number cubes Basically, the program starts out with the simplest of linear equations, such as 2x = 6 or x + 5 = 10. Students use a blue pawn for the unknown (for the 'x') and number cubes for the constants. From level II on, they use a white pawn for (-x), also called a "star", and denoted with x. The equations are modeled on the balance so that the left side of the equation goes on the left side of the balance, and similarly for the right side.

Students are instructed about "legal moves" with which to "play" with the equation until they arrive to the solution. The legal moves of course correspond to the regular principles used in algebra. For example:

  • In level I, lesson 3, students are told they can remove the same number of pawns from both sides, and the scale will still balance.
  • In level II, lesson 9, students are instructed that a pawn and a "star" (the white pawn) are opposites, canceling each other. (Pawn corresponds to x, and star to -x).
  • In level II, lesson 12, students are taught about a "convenient zero"—essentially adding (x + (-x)) to one of the sides, after which it is possible to remove pawns or stars from both sides, whichever the need might be.

Once students have mastered the setup and have solved the equations using the game pieces, they are also taught how to set up and solve the equations using paper and pencil and a pictorial notation. From this, they can then easily transition to regular algebraic notation using "x".

My impressions

I started both my girls with this program. At the time of this writing, the older was 9, studying 6th grade in Math Mammoth. She breezed through Hands-On Equations and it was fairly easy for her. Setting up an equation for the word problems (in the Introductory Word Problems book) was a little bit difficult at times. However, she cpi;d easily solve all the word problems in that book without using the balance scale.

The easiness may be partly due to the fact that Math Mammoth includes simple equations in grades 4-6, and even two lessons about solving equations using a balance. Those two lessons correspond to the first few lessons of Hands-on Equations in difficulty.

The younger also started out enthusiastically, but somewhere along the way the equations got too difficult and confusing to her—which is not surprising as she was only 7. But she had no difficulties in level I.

I think this is a terrific supplement to any math curriculum and truly helps students to think algebraically and teaches them how to solve equations. It is a great program for students in grades 4-6, preparing them for pre-algebra. You could ALSO use it with students who lack motivation and need to get that "spark" back, or just to show students how fun math can be!

Then, as far as pre-algebra and algebra students, being a physical manipulative, I feel it benefits MOST those students who have trouble understanding the abstract concepts in beginning algebra. It lets students TOUCH, FEEL, SEE, and manipulate the pieces, which makes the concepts "come alive." I don't think it is necessary for strong algebra students—they can grasp the principles and "visualize" the equations even without a manipulative.

Hands-On equations materials

You might wonder, does this system REPLACE the instruction for algebra? No, not by any means. First of all, a typical algebra course (such as algebra I) covers many more topics than just linear equations. Secondly, Hands-On Equations does not deal with all possible variants of linear equations. It does not include cases where you have fractions or decimals in the equation.

However, it CAN replace the beginning instruction for linear equations (as in pre-algebra or algebra 1). After or during the program, students will need to learn the regular notation for solving equations so that they can then solve linear equations with fractions and decimals and study other topics in their algebra curriculum.

Hands-On Equations®. Price: $34.95 - a complete program for one student. You can purchase separately an instructional DVD, Verbal Problems Introductory Workbook, and Verbal Problems Book. Bundle Option: Hands-On Equations Deluxe Home Set:$69.95. Class sets of materials are available for schools.
