What are algebraic word problems?
Algebraic word problems are questions that require translating sentences to equations, then solving those equations.
The equations we need to write will only involve
and a single variable. Usually, the variable represents an unknown quantity in a real-life scenario.
On the test, there are also word problems involving two overlapping groups that we can model and solve with

•Translating sentences to equations
•Solving linear equations with one variable
•Evaluating algebraic expressions
•Solving problems using Venn diagrams
Solving algebraic word problems requires us to combine our ability to create equations and solve them.
To solve an algebraic word problem:
1.Define a variable.
2.Write an equation using the variable.
3.Solve the equation.
4.If the variable is not the answer to the word problem, use the variable to calculate the answer.
A Venn diagram is a visual representation of two or more groups and their overlap. In a Venn diagram, each circle represents a group with a
. The overlap between the circles represent members of the groups that have
. The non-overlapping part of each circle represents members of the group that have
.
Each part of the Venn diagram is related by the following equations:
A+B−both=totalonlyA+onlyB+both=totalonlyA=A−bothonlyB=B−both

Example 1: Solve for x. x + 8 = 12. Solution: Here is the equation to solve: x + 8 = 12. We need to leave x alone on one side of the equation. For this, we must take 8 out of both sides. So, x + 8 – 8 = 12 – 8. or, x = 4. Example 2: Determine if the value 3 is a solution of the equation: 4x – 2 = 3x + 1. Solution:

Best for: 1st grade, 2nd grade. 1. Adding to 10: Ariel was playing basketball. 1 of her shots went in the hoop. 2 of her shots did not go in the hoop.
Example 1:Write an algebraic expression for the math phrase ” the sum of a number and four”. Solution:The word “sum” immediately gives us the hint that we are going to add here. Notice that we want to add two quantities: one unknown number and the number 4. Since we don’t know the value of the number, we can use a variable to represent it.
