Strategies for Solving Word Problems

The simple addition of those words ramps up the difficulty (and sometimes the math anxiety) by about !

How can you help your students become confident word problem solvers? By teaching your students to solve word problems in a step by step, organized way, you will give them the tools they need to solve word problems in a much more effective way.

Here are the seven strategies I use to help students solve word problems.

1. Read the Entire Word Problem

Before students look for keywords and try to figure out what to do, they need to slow down a bit and read the whole word problem once (and even better, twice). This helps kids get the bigger picture to be able to understand it a little better too.

2. Think About the Word Problem

Students need to ask themselves three questions every time they are faced with a word problem. These questions will help them to set up a plan for solving the problem.

Here are the questions:

A. What exactly is the question?

What is the problem asking? Often times, curriculum writers include extra information in the problem for seemingly no good reason, except maybe to train kids to ignore that extraneous information (grrrr!). Students need to be able to stay focused, ignore those extra details, and find out what the real question is in a particular problem.

B. What do I need in order to find the answer?

Students need to narrow it down, even more, to figure out what is needed to solve the problem, whether it&#;s adding, subtracting, multiplying, dividing, or some combination of those. They&#;ll need a general idea of which information will be used (or not used) and what they&#;ll be doing.

This is where key words become very helpful. When students learn to recognize that certain words mean to add (like in all, altogether, combined), while others mean to subtract, multiply, or to divide, it helps them decide how to proceed a little better

Here&#;s a Key Words Chart I like to use for teaching word problems. The handout could be copied at a smaller size and glued into interactive math notebooks. It could be placed in math folders or in binders under the math section if your students use binders.

One year I made huge math signs (addition, subtraction, multiplication, and divide symbols) and wrote the keywords around the symbols. These served as a permanent reminder of keywords for word problems in the classroom.

C. What information do I already have?

This is where students will focus in on the numbers which will be used to solve the problem.

3. Write on the Word Problem

This step reinforces the thinking which took place in step number two. Students use a pencil or colored pencils to notate information on worksheets (not books of course, unless they&#;re consumable). There are lots of ways to do this, but here&#;s what I like to do:

  • Circle any numbers you&#;ll use.

 

  • Lightly cross out any information you don&#;t need.

 

  • Underline the phrase or sentence which tells exactly what you&#;ll need to find.

4. Draw a Simple Picture and Label It

Drawing pictures using simple shapes like squares, circles, and rectangles help students visualize problems. Adding numbers or names as labels help too.

For example, if the word problem says that there were five boxes and each box had 4 apples in it, kids can draw five squares with the number four in each square. Instantly, kids can see the answer so much more easily!

5. Estimate the Answer Before Solving

Having a general idea of a ballpark answer for the problem lets students know if their actual answer is reasonable or not. This quick, rough estimate is a good math habit to get into. It helps students really think about their answer&#;s accuracy when the problem is finally solved.

6. Check Your Work When Done

This strategy goes along with the fifth strategy. One of the phrases I constantly use during math time is, Is your answer reasonable? I want students to do more than to be number crunchers but to really think about what those numbers mean.

Also, when students get into the habit of checking work, they are more apt to catch careless mistakes, which are often the root of incorrect answers.

7. Practice Word Problems Often

Just like it takes practice to learn to play the clarinet, to dribble a ball in soccer, and to draw realistically, it takes practice to become a master word problem solver.

When students practice word problems, often several things happen. Word problems become less scary (no, really).

They start to notice similarities in types of problems and are able to more quickly understand how to solve them. They will gain confidence even when dealing with new types of word problems, knowing that they have successfully solved many word problems in the past.

 

If you&#;re looking for some word problem task cards, I have quite a few of them for 3rd &#; 5th graders.

This 3rd Grade Math Task Cards Bundle has word problems in almost every one of its 30 task card sets.

There are also specific sets that are dedicated to word problems and two-step word problems too. I love these because there&#;s a task card set for every standard.

right. As I was saying, in order to find out how many more pints they need to collect to meet their goal, you would have to subtract minus 50 nine, Right When we subtract, you should always start at your ones. Calm in here. We have a zero, and I need to take away nine ones. Well, I can't do that when I don't have any ones to begin with. So that means I would need to go to my next door neighbor and try to regroup when I come here to the tens. Calm. You don't have any tens either, Genes. In order to subtract, I need to go all the way to my hundreds, fall and take the away. Now, I've taken away. I could move that which is really 10 tens to the tens call. But I still need someone's that I could take away nine. Which means I'm gonna take a 10 away from the tens. Call, which means now we have nine tens and move that 10 to the ones call. Now I'm able to subtract properly. 10 minus nine equals one nine minus five equals four zero minus zero is zero. Which means the American Red Cross needs to collect 41 more pints of blood to meet their goal. Now, I'm not quite done because I still need to check for reasonable this. Well, in order to check subtraction, I would use the inverse operation, which is addition. And I would say to myself, OK, I think they need 41 more pints, and they already had So if I put those two amounts together, do I indeed get their goal of ? Well, let's see, one plus nine equals 10 so I'll put my zero here and then move my 10 to the tens. Call. One plus four is five and five plus five is Tim. So I do indeed get their goal of points, which means my answer of 41 is a very reasonable answer. When you're working today, make sure you go and use those problems loving steps. Read each problem carefully. Look for the key words. Make a plan based on what the question is asking. Make sure to solve and show work, whether it's a number sense or drawing a picture. And finally, don't forget to check for reasonableness
