Introduction

Do you often find your child discouraged when tackling P5 Math word problem sums?

This might be because your child is overwhelmed by the amount of information given in the question, causing him/her to be unsure of where to start.

In this blog post, we will be discussing how your child can determine which questions can be solved using the Number X Value Method.

## Identifying Keywords

The first tip I give my students when solving Math word problems is to highlight the keywords they need to solve the problem.

Let’s identify the keywords in the question!

In the first sentence, the keywords are the number of tokens that each child and adult received — every child was given 10 tokens, while every adult was given 15 tokens.

Moving on to the second sentence, the keywords here are thrice as many adults as children. It tells us that there are three times more adults than children in the event.

In the next sentence, we were given the total number of tokens — 880 tokens were given out to them.

Lastly, the question wants to know how many adults were in the event.

## Unit X Value (Number X Value) Method

To solve this question, we will be using the Number X Value Method. However, I prefer to call it the Unit X Value Method because it is easier for you to remember — like the UV (ultraviolet rays)! ☀️

✖️ What Is the Unit X Value Method? ✖️

It is an answering technique used to solve Math word problems as long as they have 3 pieces of information:
1. Individual Value
2. Total Value
3. Individual Units

Let us draw the UV Table ☀️ first to help illustrate how to use the Unit X Value Method!

Next, we will fill in the information needed. For the Units, there are thrice as many adults as children. So we are going to put 1 unit for children and 3 units for adults.

For the Value, it is given in the question that every child will receive 10 tokens, while each adult will receive 15 tokens.

Lastly, to get the value of our UV ☀️, we will multiply Units with Value.

Take note that the table above represents 1 set because we are comparing one child for every three adults.

Now, let us compute the total number of tokens that will be spent on each set.

For each set, the child and the adults will receive 55 tokens.

It is given that the total number of tokens is 880. How can we compute the number of sets? Let’s divide!

Let us now answer the question. How many adults were there at the event? Let us look at the highlighted part.

For each set, we have 3 adults.

If we have 16 sets, how many adults would be there?

Therefore, there are 48 adults in the event.

## Unit X Value Question Variation

One common issue that students tend to face when solving this type of question is failing to draw the UV Table ☀️.

☀️ Why Is It Important To Draw The UV Table? ☀️

It is important to draw this table so that you can always refer to it even if the question is asked in a different way.

How are you going to approach it?

In this case, we will be getting the difference between the number of adults (which is 3 units) and the number of children (which is 1 unit).

This means that for every 1 set, we will have 2 more adults.

If there are 16 sets, that means:

Therefore, there are 32 more adults.

## How Can This Question Be Tested Differently?

Sometimes, the questions will not be as straightforward as the others like the example above. It will not give you the exact amount and just say it is “\$3 more.”

Therefore, you’d have to compute for that too before proceeding with the steps that you learned in this blog post.

## Conclusion

I hope that after reading this blog post, you have gained an understanding of when to use the Unit X Value Method. Remember to check for these 3 key information — Individual Value, Total Value, and Individual Units.

Also, keep in mind to draw the UV Table ☀️ because it will serve as your guide in approaching any variation of the question!
