Steps to Take When Solving Addition and Subtraction Word Problems Word problems can scare away the kids because they seem very complicated for young minds. Many kids struggle to solve these problems and look for shortcuts to find the answer. These shortcuts might help the kids, but these do not work in all addition and subtractions word problems. Here is a five-step guide to help the kids overcome the fear of solving word problems. Step 1: Read - Before starting a solution to a word problem, reading it is the most important step. Begin with reading the problem slowly and carefully. Read it more than once for maximum understanding. Step 2: Underline - After you have understood the words, start underlining the important facts in the problem. It will help you focus on the important numbers in the problem. Step 3: Draw - Visualization is the next step in solving the word problem. Draw a picture of the problem, and it will help you understand the problem better. Step 4: Write a Sentence - Use the drawing and the underlined information to write a number sentence. Step 5: Solve - Read the sentence and solve it! These five steps can help you solve even the most complicated addition or subtraction word problem with ease!
In this worksheet set students are introduced to the concept of word problems and how to spot and perform addition and subtraction within word problems.




Quick Tips for Solving Questions Like This:

The first tip is pretty obvious. Start by pay attention to the keywords in the language that you are provided with. If you see the following phrases or words: altogether, and, combine, increase, more than, plus, sum, or total; you can quickly understand that you will be adding two or more values together. Likewise, if you see the phrases or words: decrease, difference, fewer than, left with, less than, minus, or take away; you will need to subtract two or more values. Some problems may use words to indicate numbers. We would encourage you to write those words as numbers. To make the problems more real for you, we would encourage you to draw the problems into simple diagrams for yourself. It is much easier to see if something makes sense visually. You will not be able to do this with problems that involve very large numbers, but a general guided drawing can go a long way in those cases. The more practice you get with this, the easier it will be for you.




Example Addition Word Problem

Pizza Eater

Greg Guacamole and Peter Pineapple went out and bought a few slices of pizza for dinner. Greg had 4 slices of pizza and Peter had 3 pieces of pizza. They put all their pizza into a pizza box. How many slices of pizza were in that box?

Solution: The "all their pizza" tells us they we are looking for a total. To this we just find the sum of all of the slices of pizza that we have. Greg has 4 slices and Peter has 3, so the total would be equal to their sum.

4 + 3 = 7
The answer would therefore be 7 slices of pizza in total.


Example Subtraction Word Problem

Working off of the previous word problem (above). Later that same day, Peter Pineapple went in the refrigerator and grabbed that box of pizza and there were only 2 slices of pizza left in box. Greg Guacamole ate those slices. If there were originally 7 slices in the box, how many slices did Greg eat?

Solution: The box started with 7 slices and after Greg ate, there were only 2 slices left. This means that we need to find the difference between the number of slices remaining (2) and how many slices we started with (7). To put this in math terms:

7 - 2 = 5.
So, Greg must have eaten 5 slices in total. Man, that is a lot of pizza.
