Worksheet Overview

QUESTION 1 of 10

Most of us have heard of scrambled eggs, but did you know words can be scrambled too?  

 

We need your best efforts to help us unscramble this lot.

Are you up for the challenge word detective?

 

Here 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.

 

What could be the special pattern below?

 

eat, eating          look, looking          fish, ____

 

Did you notice that each word has had -ing added to the end of it?

 

This is our special pattern for these words!

 

This makes our missing word FISHING.

 

So the complete set of words would be:

eat, eating          look, looking          fish, fishing

 

Young boy fishing

 

 

 

Let's investigate some more word groups now. 

 

Look at these word pairs.

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

 

kick, kicked          jump, jumped          bash, ____

 

Did you notice that the letters -ed are being added to the end of the first word each time?

 

This makes our missing word BASHED.

 

Cartoon broken window

 

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!

Are you ready to crack some word-based cases detective? 

 

Here are some two groups of words:

  • Question 1

Are you ready to crack some word-based cases detective? 

 

Here are some two groups of words:

 

[comfort, uncomfortable]

[predict, ____ ]

 

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
Unpredictable
EDDIE SAYS
The second word in each pair has had the prefix un- and the suffix -able added to make the word longer. This means that the second word in each set has an opposite meaning to the starting word, plus instead of a verb it has become an adjective. In some of these challenges, our word will get shorter as letters are removed and, in others, it will get longer as letters are added. Be on the lookout for both of these options, word detective!
  • Question 2

Here are some more groups of words to explore:

 

[presenting, sent]

[pretending, ____ ]

   

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

 

Following the same pattern as the first and second pairs, find the missing word.

CORRECT ANSWER
Tend
EDDIE SAYS
The second word in each group has had the prefix pre- and the suffix -ing removed to make it shorter. Are you familiar with the word 'tend'? It can mean to look after or to behave in a certain way. If you did not know this word, then make a note of it in your personal log now.
  • Question 3

Here are a dastardly duo to rearrange:

 

[previews, view]

[prearranges, _____ ]

 

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

 

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

CORRECT ANSWER
Arrange
EDDIE SAYS
Star effort there! The second word in each group has had the prefix pre- and the letter -s removed to make a shorter word. The prefix 'pre' usually means before or prior to, so if something is 'prearranged' it means that it has been arranged in advance. How are you doing with these challenges so far, word wizard?
  • Question 4

Explore the new words below:

 

[clear, unclearly]

[deserved, ____ ]

 

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
Undeservedly
EDDIE SAYS
A long word this time! The second word in each pair has had the prefix un- and the suffix -ly added to it. They're getting a bit trickier, aren't they? If you find these a bit challenging, try writing the first word directly above the second word and then cross out or use dashes to show spaces, so that you can compare how they have changed.
  • Question 5

You're halfway through already, word detective!

 

Here are two new pairs of words:

 

[stand, understands]

[estimate, ____ ]

 

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

 

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

CORRECT ANSWER
Underestimates
EDDIE SAYS
The second word in each group has had the word under- and the letter -s added to make the word longer. The prefix 'under' means less than, lower or beneath. So if you 'underestimate' someone, it means that you estimate them to be less important or to have less skill than they do. Remember to make a note of any words that are new to you and look them up in a dictionary to find out what they mean.
  • Question 6

Consider the new word suspects below:

 

[replanted, plant]

[researched, ____ ]

 

Plant seedling in green pot

 

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

 

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

CORRECT ANSWER
Search
EDDIE SAYS
Did you get this one? The second word in each group has had the prefix re- and the suffix -ed removed to make the word shorter. This has removed the sense of repetition which the starting words have, and changed the verb from the past to the present tense. You just have a couple more mysteries to solve now, word detective!
  • Question 7

Review the words below:

 

[boat, lifeboats]

[line, ____ ]

 

 

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

 

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

CORRECT ANSWER
Lifelines
EDDIE SAYS
The second word in each group has had life- added at the start and the letter -s added at the end to make a longer word. Can you remember what the effect of adding an '-s' at the end has? That's right, it makes our nouns plural!
  • Question 8

Here are two new groups of words:

 

[act, reacted]

[appear, ____ ]

 

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
Reappeared
EDDIE SAYS
The second word in each group has had the prefix re- and the suffix -ed added to make a longer word. This has changed the starting verb into the past tense, plus added a sense of performing the action again or repeatedly. In this activity, you are REsolving many mysteries!
  • Question 9

Here are your penultimate word groups to investigate: 

 

[consider, reconsiders]

[write, ____ ]

 

Young girl writing

 

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.

CORRECT ANSWER
Rewrites
EDDIE SAYS
You're nearly there, word detective! The prefix re- and the ending -s have been added to the second word in each group to make a longer word. Did you spot that the prefix 're' means again in these two words? To reconsider means to think again, and to rewrite something means to write it once more.
  • Question 10

Here's your final set of suspicious words:

 

[upstanding, stand]

[upbringing, ____ ]

 

The second word is missing in one of the groups.

 

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

CORRECT ANSWER
Bring
EDDIE SAYS
The prefix up- and the suffix -ing have been taken off the second word in each group to make it shorter. Well done, you've completed this activity and your word scramble skills are improving! You can now add and remove prefixes and suffixes at the same time to find a missing word.
