Translating Word Problems to Addition Equations
To model a situation where a quantity is added to an unknown value to get a total, we use an equation of the form x + a = b. Here, x represents the unknown starting amount, a is the amount added, and b is the final total. Translating real-world problems into equations helps us solve them systematically. First, identify the unknown quantity and assign it a variable, like x. Then, look for keywords like "plus," "added to," "increased by," or "sum" that indicate addition. This skill is part of Grade 6 math in Reveal Math, Course 1.
Key Concepts
Property To model a situation where a quantity is added to an unknown value to get a total, we use an equation of the form $x + a = b$. Here, $x$ represents the unknown starting amount, $a$ is the amount added, and $b$ is the final total.
Examples After receiving 8 new text messages, your phone shows you have 25 total messages. To find the original number of messages, $m$, you can write the equation: $m + 8 = 25$. You add 1.5 gallons of gasoline to your car, which brings the total amount of gas in the tank to 7.8 gallons. To find the amount of gas you started with, $g$, you can write the equation: $g + 1.5 = 7.8$.
Explanation Translating real world problems into equations helps us solve them systematically. First, identify the unknown quantity and assign it a variable, like $x$. Then, look for keywords like "plus," "added to," "increased by," or "sum" that indicate addition. The final step is to set up the equation by showing how the initial amount, the change, and the total are related.
