Overview

Algebra concepts should be incorporated with elementary and middle school mathematics

Math problems can be solved in multiple ways Everyone thinks different

You can take a none algebraic problem and make it algebraic Manipulatives

Even college students have trouble with algebra

NCTM and NETS StandardsNETS standards This article does inspire students to think of

creative ways to solve math problems Using manipulatives

There is really no mention of technology in this article

NCTM website [grades 6-8] This article does “recognize and generate

equivalent forms for simple algebraic expressions and solve linear equations”

“develop an initial conceptual understanding of different uses of variables”

Key Points Algebra can be easier to learn if it’s

incorporated earlier in the learning process Using manipulatives is nothing but

beneficial Hands on Visual Makes math problems more fun and practical

You can take manipulatives and turn them into variables in an algebraic problem

Example Using Manipulatives

Example Using Variables

Strengths Lots of specific examples Examples provide step by step reasoning and demonstration Explains reasoning as to why she is teaching her students the way she is Explains why the lesson is important for students Author explains in one part that she does not want to remind students what to do

because she was “Interested in discovering what they would do when it was their turn to explore problems with manipulatives”.

The use of a visual approach leading into using variables was a good transition. Ex: drawing a football, soccer ball, and baseball and later switching it to F, S, and B.

Use classroom examples of college students, to show that we might need more work in trying to act like “elementary students”. Example: “It is interesting to note that a few students did solve the problems by using variables, even though I asked them not to. When I asked them why, they responded that they were so used to solving problems of this type by using variables that they could not solve them without using variables. The students’ struggles suggested to me that these preservice teachers need more practice with these strategies if they are expected to naturally implement them in their own classrooms.”

Weaknesses When the author is describing her examples,

for each step she states the fact first, followed by the explanation. When the author says “From fact 2, he finds the soccer ball’s weight,” it makes it a little difficult to follow along with.

Spends a lot of time focusing on algebra, but when it comes to the elimination by subtraction part seems to go through it very fast.

No technology mentioned

How could technology be implemented into the classroom?

All of the examples provided in the article could be displayed using a SmartBoard, or PowerPoint. Quizzes, Tests, Classroom activities, Homework

could be implemented using technology The article does not show any

implementation of technology.
