Worksheet Overview

QUESTION 1 of 10

When people get tired they sometimes say that 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 our complete set of words would be:

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

 

A group of green 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, ____ )                      

 

Smiling jam biscuit

 

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.

  • Question 1

Right, word detective, are you ready to go?

 

Here are two groups of words:

 

[appear, pears]

[rewind, ____ ]

 

A green pear

 

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

 

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

CORRECT ANSWER
Winds
EDDIE SAYS
How did you get on with this first challenge detective? The first word in each group has had its first, second and last letters removed and the letter -s added at the end, in order to create the second word. So if we drop the first, second and last letters of 'rewind', we reach 'wind', then we just need to add an -s at the end to get find our answer. Remember that letters can be both added and/or removed to create the second word in each group.
  • Question 2

Here are two new groups of words:

 

[unsatisfactory, satisfactorily]

[uneasy, ____ ]

   

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

 

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

CORRECT ANSWER
Easily
EDDIE SAYS
How did you get on with this mystery? The first word in each group has had its prefix un- removed and its last letter replaced with -ily in order to create the second word. This has had the effect of changing the negative adjectives of the first words into a positive adverb. Did you spot that detective?
  • Question 3

Consider the new groups of word suspects below:

 

[faded, file]

[trees, ____ ]

 

Group of palm trees blowing in the wind

 

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

 

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

CORRECT ANSWER
Tile
EDDIE SAYS
A challenging one here! The first word in each group has had all of its letters, except the first, removed and replaced with -ile in order to create the second word. Wow, we had a lot of letters to switch out there - were you able to keep track of them all?
  • Question 4

Check out this next dastardly duo:

 

[chosen, shower]

[clones, ____ ]

 

Boy in shower

 

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. 

CORRECT ANSWER
Slower
EDDIE SAYS
Let's start by identifying the letters which stay the same in the first pairing - they are l, o and e (which are the second, third and fifth letters). If we apply this to the second pairing, then 'clones' becomes: _ l o _ e _ What have the other three letters been replaced with? The first letter has been replaced with an s, the third with a w, and the last with an r. If we add a s, w and r into the gaps here, we reach: _ l o _ e _ -> s l o w e r Were you successful with this one, word detective?
  • Question 5

Review these new word pairings:

 

[hoof, aloof]

[jive, ____ ]

 

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

 

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

CORRECT ANSWER
Alive
EDDIE SAYS
The first word in each group has had its first letter removed and replaced with al- 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:

 

[proud, crowds]

[trail, ____ ]

 

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

 

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

CORRECT ANSWER
Crawls
EDDIE SAYS
How did you get on here? So three of the letters have stayed the same here, two have switched and an -s has been added to the end. If we start with our constant letters, we reach: _ r a _ l The letters we need to add in are c and w, plus the -s on the end too. If we add these in, then we find: _ r a _ l -> c r a w l s 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:

 

[unlock, leak]

[unpick, ____ ]

 

Leaking oil drums

 

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

 

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

CORRECT ANSWER
Peak
EDDIE SAYS
Top effort! The first word in each group has had its prefix un- removed and its fourth and fifth letters changed to ea 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 can apply this learning to your upcoming missions.
  • Question 8

Investigate the words which are getting scrambled below:

 

[boat, floats]

[door, ____ ]

Drawing of a motorboat

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

 

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

 

CORRECT ANSWER
Floors
EDDIE SAYS
The first word in each group has had its first letter replaced with fl- plus an -s added at the end, in order to create the second word. Hopefully this challenge didn't FLOOR you, detective?
  • Question 9

Here are your penultimate word groupings to un-jumble: 

 

[copier, happier]

[ripens, ____ ]

 

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

 

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

CORRECT ANSWER
Happens
EDDIE SAYS
The first word in each group has had its first and second letters changed to hap- in order to create the second word. You're onto your final mission already, word detective - good luck!
  • Question 10

Your last mission already - well done!

 

Here are your final groups of words:

 

[please, treats]

[around, ____ ]

 

The second word is missing in one of the groups.

 

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

CORRECT ANSWER
Trouts
EDDIE SAYS
So only two of the letters have stayed the same here, and a huge four have switched! If we start with our constant letters, we reach: _ _ o u _ _ The letter pairs we need to add in are tr- and -ts. If we add these in, then we find: _ _ o u _ _ -> t r o u t s What a treat, this activity is now complete! You can now spot a pattern involving changing multiple letters, which have been affected by more than one switch, then apply this to find a missing word.
