# Complete the Word Pair Using Patterns

In this worksheet, students will work out a pattern involving changing multiple letters and more than one rule at the same time, then apply this to find a missing word. It will develop their problem solving and sequencing skills.

### QUESTION 1 of 10

When people get tired they sometimes say their brains are scrambled!

Well, there is no room for that here, as we need your best brainpower to unscramble the following words.

Challenge accepted word detective?

Below are some pairs of words.

They each follow a special pattern and we need to find out what each pattern is!

You need to think about what the pattern is between the first two pairs, and then complete the third pair in the same way.

Let’s look at an example together now.

What could be the special pattern below?

(extending, nets)          (attests, sets)          (cheaply, ____ )

If you look closely, you will notice that the second word is made up of the 5th, 4th and 3rd letters of the first word (in that order) and then an -s is added onto the end.

We need to do the same for the word cheaply.

This gives us pea, then add the -s and we get PEAS. YUM!

So the complete set of words would be:

(extending, nets)          (attests, sets)          (cheaply, peas)

Let’s investigate another example now.

Look at these word pairs.

Can you work out the special pattern and figure out which word comes next?

(cabled, able)          (trains, rain)          (smiles, ____ )

Did you notice that the first and last letters are being removed each time?

We need to do the same for smiles and this gives us the answer MILE.

Pssstt!! Here's a handy hint to help you reach superstar status:

Remember to check if any letters have been added or removed from the word.

In this activity, you will need to be a word detective and work out the missing word in a pair.

Let’s get started!

• Question 1

Welcome to another exciting activity, word detective!

Here are two groups of words:

[rise, arose]

[wake, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Awoke
EDDIE SAYS
Did you solve this first mystery? The first word in each group has had its second letter changed to an o, plus the letter a added at the start, in order to create the second word. So two changes have been made to our original words - did you spot both, word detective?
• Question 2

Here are two new groups of words:

[choir, chairs]

[shore, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Shares
EDDIE SAYS
How did you get on here? The first word in each group has had its third letter changed to an a, plus the suffix -s added at the end, in order to create the second word. The effect of these changes is that the word has converted to a different noun and become plural too.
• Question 3

Consider the new groups of word suspects below:

[chuck, cheeky]

[slurp, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Sleepy
EDDIE SAYS
A tricky case to crack here! The first word in each group has had its third and fourth letters changed to ee, plus the the letter y added to the end, in order to create the second word. Hopefully you're not feeling SLEEPY detective - keep up the super sleuthing!
• Question 4

Check out this next dastardly duo:

[burps, beeping]

[moats, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair of words, find the missing word.

Meeting
EDDIE SAYS
Let's start by identifying the letters which stay the same in the first pairing - they are b and p (which are the first and fourth letters). If we apply this to the second pairing, then 'moats' becomes: m _ _ t _ What have the other three letters been replaced with? The first pair of letters has been replaced with ee and the s has been replaced with the suffix -ing instead. If we add ee and ing into the gaps here, we reach: m _ _ t _ -> m e e t i n g Were you able to un-scramble this one, word detective?
• Question 5

Review these new word pairings:

[swashes, washed]

[smashes, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Mashed
EDDIE SAYS
The first word in each group has had its final letter changed to a d, plus the letter s removed from the start, in order to create the second word. If there are any words used here which you are unfamiliar with, look them up in the dictionary now and make a note of them in your personal word log. You're halfway through your cases already detective - great work!
• Question 6

Here are two new groups of words:

[shrimp, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Ship
EDDIE SAYS
How did you get on here? The first word in each group has had its third and fifth letters removed in order to create the second word. Were you able to put those clues together to find the culprit in this case?
• Question 7

Nearly there, word detective!

Consider the new word groupings below:

[tame, stale]

[type, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Style
EDDIE SAYS
Top effort! The first word in each group has had its third letter changed to an l, plus a letter s added at the start, in order to create the second word. Lots of steps to put together in that one detective, don't worry if you made a slip along the way, as long as you can understand where you made it and apply this learning in the cases you attempt from now on.
• Question 8

Investigate the words which are getting scrambled below:

[towel, trowels]

[tough, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first pair, find the missing word.

Troughs
EDDIE SAYS
We have two new letters added being added here, which makes our second word much longer than our first! The first word in each group has had a letter r added between the first and second letters plus a letter s added at the end, in order to create the second word. Hopefully you didn't find this challenge too TOUGH detective?
• Question 9

Here are your penultimate word groupings to un-jumble:

[dreams, scream]

[tribes, ____ ]

The second word is missing in one of the groups of words.

Following the same pattern as the first two groups, find the missing word.

Scribe
EDDIE SAYS
The first word in each group has had its first and second letters changed to sc- in order to create the second word. Also, the new word has been made plural by adding the suffix -s at the end of the word. You're onto your final mission already, word detective - amazing work!
• Question 10

Your last mission already - well done!

Here are your final groups of words:

[sipping, slip]

[sopping, ____ ]

The second word is missing in one of the groups.

Following the same pattern as the first pair, find the missing word.

Slop
EDDIE SAYS
So three of the letters have stayed the same here, and our word has become a lot shorter! If we start with our constant letters, we reach: s _ o p _ _ _ _ The letter we need to add into the empty second position is l, but we also need to remove the final four letters too. If we add this letter in and remove the -ping ending, then we find: s _ o p _ _ _ _ -> s l o p You've completed all of these challenges - hooray! You can now spot a pattern in changing multiple letters, which have been affected by more than one switch, then apply this to find a missing word.
