| Research Studies | Pre- and Post-tests for Levels I, II and III

Studies in more than 135 classrooms in 17 states involving more than 2500 students have yielded unequivocal evidence of the ability of elementary and middle school students to **quickly** learn basic algebraic concepts through the use of the Hands-On Equations method of instruction, and to transfer their learning to the pictorial representation.

**Comparable achievement by 4th, 6th and 8th grade groups**

The result of three research studies involving a total of 22 classrooms and 418 students is summarized above. The percentages shown are the grade group averages for the given test. We note that at each grade level 1) the students had a large gain from the pre-test to each of the post-tests, 2) the students did equally well using the pictorial notation (last column) as they did in using the game pieces (middle column), and 3) **the program is age-blind**: the 4th graders did as well as the 6th and 8th graders. Pre-test questions: a) 2x = 8, b) x + 3 = 8, c) 2x + 1 = 13, d) 3x = x + 12, e) 4x + 3 = 3x + 6, and f) 2(2x + 1) = 2x + 6. Click here for the full report.

**Impressive results in just 7 lessons**

The table above shows the gain the 4th graders made in only seven lessons. We note that 79% of these 4th graders, 60% of whom were inner city students, were able to successfully solve the equations 4x + 3 = 3x + 8 after seven lessons of instruction. It is worth noting that the retention test was administered three weeks after the instruction for Lesson #7, with no Hands-On Equations instruction in the interim. Furthermore, **the retention test was taken without the use of the game pieces.** Click here to view the full report.

*"Based on our findings, we suggest mathematics teachers endeavor to use Hands-On Equations materials and pictorial representations to help students develop a conceptual basis for translating and solving word problems involving linear equations with one unknown." (Page 12)*

*"After the class interventions, all teachers regarded their physical manipulative group lesson as the most successful. They reasoned that the physical manipulative provided students with a concrete and tactile learning experience and also facilitated students’ individual and group languaging. In their opinion, when physically handling the manipulative, students concretely constructed conceptual understanding of: 1) equation equivalence through the balance scale; 2)constants and variables through their distinct representations (number cubes and pawns); and 3) performing the same operation on both sides of the equation through actual action of removing the same elements from both sides of the balance scale. Thus, the physical manipulative groups had a better understanding of equation concepts compared to the other groups." (Page 178)

*"It is important to realize that no content is developmentally appropriate or inappropriate in and of itself...During the development of algebraic understanding, the learner moves from concrete to abstract thinking. Henry Borenson's work with fourth graders, who according to cognitive stage theory are generally expected to be in the concrete operational stage, shows that they are able to transition to abstract thinking if they initially experience algebraic principles using concrete manipulatives along with symbolic representations (Borenson & Barber, 2008). An effective instructional strategy begins with transforming the word problem into a concrete or pictorial equation. When the learner becomes proficient with creating and interpreting concrete representations of equations, the teacher can demonstrate how to use that representation to construct an abstract equation using a letter for the unknown. The concrete representation can be used as long as the learner requires the structure, which may be different lengths of time for different students." (Pages 18 - 19) *

*"...moving from concrete to abstract thinking is key to understanding algebra, with which many students struggle, particularly at younger ages, when they theoretically are in Piaget's concrete operational stage. However, Henry Borenson's work with young children using his Hands-On Equations program (available as a series of apps as well as in physical individual and classroom-scale programs) demonstrates that if children experience algebraic principles using concrete strategies initially, then the transition to abstract thinking can occur at younger ages (Borenson and Barber 2008)*" (Page 38).

*"By first teaching the concept of equivalence nonsymbolically, using the balance model or using concrete objects, and only afterward relating that learning to the symbolic notation, we can provide young students with a successful introduction to the relational meaning of the equal sign."

"*In the physical environment, students could pick up and move the algebra pieces easily without the use of a mouse. Their movements were more efficient with the algebra pieces. Because the algebra pieces were more open-ended and did not provide students with a guided process for solving the equations, this encouraged some students to invent their own strategies for solving equations, rather than following a traditional algorithm...The open-ended feature of Hands-On Equations also prompted students to use more mental mathematics in their calculations and allowed them to process numerical relationships mentally before writing down their ideas."

They are able to reactivate this self-evident image at any moment." (Page 355)*
