in addition, they provide her with instant feedback; if the students understand, they use the manipulatives correctly to represent expressions and solve equations. on the other hand, students who learned using manipulatives expressed 2x as two equal quantities, x + x. students who used manipulatives also expressed x2geometrically as a square with dimensions x by x. the use of the manipulative allows students who are at a concrete level of understanding to demonstrate, to represent the problem in a concrete way. if it feels really comfortable, they can do it with manipulatives and make that a stepping-stone, make that the bridge to going symbolically. the manipulatives were very helpful in the beginning of the lesson, because when i asked the students to take a guess, many of them guessed incorrectly. the lesson is a continuum where you have the students working with the manipulatives in order to lead them to understanding, building their understanding of the symbolic algebraic sentence.
the purpose of using the manipulatives was to help the students better understand the problem. my rule of thumb is: use the model with the manipulatives or a pictorial model whenever i have a simpler problem, and as i extend their facility with the algebraic solution, then they can let go of the physical model and go on to other number sets. the cups and chips manipulative is an example of an effective, yet inexpensive, manipulative that can be used in an algebra classroom. in part ii, jenny novak’s students work with manipulatives and algebra to develop an understanding of the equivalence transformations used to solve linear equations. in part i, sarah wallick’s students use a pulley system to explore the effects of one rotating object on another and develop the concept of transmission factor.

what is it? manipulatives are physical objects that are used as teaching tools to engage students in the hands-on learning of mathematics. they can be used to introduce, practice, or remediate a concept. a manipulative may be as simple as grains of rice or as sophisticated as a model of our solar system. manipulatives help students learn by allowing them to move from concrete experiences to abstract reasoning (heddens, 1986; reisman, 1982; ross and kurtz, 1993). manipulatives are physical objects that students and teachers can use to illustrate and discover mathematical concepts, whether made specifically for any object that students can touch, move, feel, and interact with is a manipulative. nctm (the national council of teachers of mathematics), using manipulatives to teach elementary mathematics, why are manipulatives important in preschool, manipulatives meaning, concrete manipulatives examples. what are manipulatives examples? why are manipulatives important in the classroom? what are manipulatives activities? what benefits does manipulatives provide to teachers in the teaching process?
