#1 -What is a Word Problem Like in Pre-Algebra
A. Word Problems Before Pre-Algebra
Firstly, students may solve simple word problems with phrases that do not include variables.
For example, students practice with word problems that involve addition, subtraction, multiplication, and division. These problems may include short keyword phrases such as “added to,” “divided by,” or “Three students carry four notebooks. How many notebooks in total?” = 3 students x 4 notebooks = 12 notebooks all together.
B. Word Problems by Sixth Grade
On the other hand, by sixth grade, key phrases become more complex. Students are introduced to variables, lowercase letters that represent an unknown value. I recommend using n as a variable to help students recognize that n represents an unknown number.
C. Complex Word Problem Phrases
Furthermore, more complex word phrases are used, such as:
- 1. Twenty-eight twice a number
- 2. A number less than three
- 3. Eight less than the product of two and n
- 4. The quotient of three and a number
Therefore, students will benefit from word lists with examples of each. Students experience significant challenges with turnaround, reversed expressions.
For example, in the phrase, “Six from a number,” the expression is written as “n-6.” Notice the reversal. Another example includes using the phrase, “a number less than three,” as “3-n”.
#2 – Color-Code
Next, use color to identify the parts of the phrase. For example, instruct students to read the problem out loud and then silently. Help identify key parts of the problem. Underline the number in blue, the operation in green, and the variable in red.
In addition, help students identify turnaround phrases such as “from,” “less than,” and “more than.”
Identify turnaround phrases … “taken from,” “less than,” and “more than”.
#3 – Write the Expression
Likewise, write the phrase as an algebraic expression. Continue to color code. For example, “Seven subtracted from a number” becomes n – 7. Practice with other examples as a whole class. Next, pair students to complete a worksheet. As the pairs work, check for understanding by visiting each pair.
#4 – Resources
On the other hand, you look for easy prep for this lesson. No problem. Below you will discover differentiated notes, color-coded and black and white.
