Worksheet Overview

QUESTION 1 of 10

The following activity is a practice exercise to help you measure your success under timed conditions. 

If you are unsure of an answer move on to the next question.  You should come back to questions you found difficult at the end if you have time.  

 

Here is a list of words:

CARD    DARK    CRAB     INKS

Here are some codes for the above words. They are not in order:

0473     2741    2470     8935

Using this information, what would be the code for DRINK?

 

To work this out you need to follow three steps:

First, match each word to its corresponding code using numbers that appear more than once.

Secondly, work out what each letter is in code.

Thirdly, work out the word, in this case DRINK, using the code you have found.

 

So let’s give it a try!

There are two codes beginning with the number 2. Do we have any words starting with the same letter?

We have two words starting with the letter C, so 2 must represent C (2=C).

 

We have two codes with the number 4 in the second letter position. Which letter appears in the second letter position twice? 4 must be the letter A (4=A).

 

We now have enough information to match each word to a code, giving us:

DARK = 0473

CRAB = 2741

CARD = 2470

INKS = 8935

So D = 0, R = 7, I = 8, N = 9, K = 3.

If we use this code on the word DRINK, we get the answer of 07893.


Now it's time to begin this practice exercise.  Good Luck!

Right then, code cracker, we're back at the number code-cracking game! You've done so well so far -  let's keep it going!

Using this information, what would be the code for HEARTY?

 

CORRECT ANSWER
613059
EDDIE SAYS
How did you get on with this one, code cracker? Remember to take your time! Rushing won't help at all and my motto is: slow and steady wins the race! If you work carefully now you will see results in the proper exams! Follow each stage carefully: 1. Match each word to its corresponding code using numbers that appear more than once: There are three codes with the number 1 in the second letter position. We have three words with E as the second letter. Therefore, 1 must be E (1 = E). The number 5 appears in the last letter position in one code and the first letter position in another. The letter T appears at the end of RENT and the beginning of TAME. Therefore, 5 must be T (5 = T). We now have enough information to match each word to a code, giving us: HELP = 6174 YEAR = 9130 RENT = 0185 TAME = 5321 2. Work out what each letter is in code: So H = 6, E = 1, A = 3, R = 0, T = 5, Y = 9 3. Work out the word: If we use this code on the word HEARTY, we get the answer of 613059.
  • Question 2

How did you get on with that, code cracker? This is not the easiest skill to master, so don't panic if you didn't get it right - use the explanations to help you!

Here is a list of words:

NICE  MEAN  SEEN  SOON 

Here are some codes for the above words. They are not necessarily in order:

4632  9254  7224  7114

Using this information, what would be the code for IMMENSE?

CORRECT ANSWER
6992472
EDDIE SAYS
Was this one IMMENSEly hard, code cracker? I hope not! Remember to try and work through it just as I laid it out in the introduction and in each explanation. Going stage by stage is crucial for success! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes in which the number 7 appears in the first letter position. The letter S appears in the first letter position in two words. Therefore, 7 must be S (7 = S). The number 4 appears in the last letter position in three codes. The letter N appears in the last letter position in three words. Therefore, 4 must be N (4 = N). We now have enough information to match each word to a code, giving us: NICE = 4632 MEAN = 9254 SEEN = 7224 SOON = 7114 2. Work out what each letter is in code: So I = 6, M = 9, M = 9, E = 2, N = 4, S = 7, E = 2 3. Work out the word: If we use this code on the word IMMENSE, we get the answer of 6992472.
  • Question 3

Remember, code cracker, we are working on building your vocabulary here as well. The long word for which I am asking you to find the code will usually be one which would work brilliantly in your creative writing work! 

Here we go again...

Here is a list of words:

SORE  VOTE  SAVE  WAVE

Here are some codes for the above words. They are not necessarily in order:

9537  3267  9217  0537

Using this information, what would be the code for SEVER?

CORRECT ANSWER
97371
EDDIE SAYS
Do you know what SEVER means, code cracker? It means to cut off. Which can be an exciting word to use in a story - especially one which might be a bit gory! To get to the answer, follow the stages as usual: 1. Match each word to its corresponding code using numbers that appear more than once: All of the codes have the number 7 in the final letter position. All of the words end with E. Therefore, 7 must be E (7 = E). The number 9 appears in the first letter position in two codes. The letter S appears in the first letter position in two codes. Therefore, 9 must be S (9 = S). The number 3 appears in the third letter position in two codes. The letter V also appears in the third letter position in two codes. Therefore, 3 must be V (3 = V). We now have enough information to match each word to a code, giving us: SORE = 9217 VOTE = 3267 SAVE = 9537 WAVE = 0537 2. Work out what each letter is in code: So S = 9, E = 7, V = 3, E = 7, R = 1 3. Work out the word: If we use this code on the word SEVER we get the answer of 97371.
  • Question 4

Right then, code cracker, I hope you're finding this activity anything but BLAND! It can be really satisfying when you find the right answer, don't you think?

And again...

Here is a list of words:

BOWL  NAIL  BODE  BIDE

Here are some codes for the above words. They are not necessarily in order:

7390  7590  6451  7321

Using this information, what would be the code for BLAND?

CORRECT ANSWER
71469
EDDIE SAYS
This word was a bit shorter, code cracker - did you find that helpful? Remember - keep working steadily and follow the stages to help you! 1. Match each word to its corresponding code using numbers that appear more than once: There are three codes with the number 7 in the first letter position. We have three words with B as the first letter. Therefore, 7 must be B (7 = B). The number 1 appears in the last letter position in two codes, as does the number 0. The letter L appears in the last letter position, as does the letter E. The number 0 appears in the last letter position in two words which begin with the letter 7. We already know that 7 = B. Therefore, 1 must be E (1 = E). We now have enough information to match each word to a code, giving us: BOWL = 7321 NAIL = 6451 BODE = 7390 BIDE = 7590 2. Work out what each letter is in code: So B = 7, L = 1, A = 4, N = 6, D = 9 3. Work out the word: If we use this code on the word BLAND, we get the answer of 71469.
  • Question 5

I am so pleased that you chose to COMMIT to the number code cracking task in hand! You are halfway - high five!

Here is a list of words:

3275  6195  6180  5160

Using this information, what would be the code for COMMIT?

CORRECT ANSWER
826693
EDDIE SAYS
I hope this is making sense to you now, code cracker. Don't panic if you haven't quite mastered it yet - we're still learning! Take the time to read over the explanation carefully, as it will really help you in the long run! 1. Match each word to its corresponding code using numbers that appear more than once: There are three codes with the number 1 in the third letter position. We have three words with A as the third letter. Therefore, 1 must be A (1 = A). The number 6 appears in the first letter position in two codes. The letter M is the first letter of MAIN and MACE. Therefore, 6 must be M (6 = M). We now have enough information to match each word to a code, giving us: TOWN = 3275 MAIN = 6195 MACE = 6180 NAME = 5160 2. Work out what each letter is in code: So C = 8, O = 2, M = 6, M = 6, I = 9, T = 3 3. Work out the word: If we use this code on the word COMMIT, we get the answer of 826693.
  • Question 6

CORRECT ANSWER
403925
EDDIE SAYS
Well done for getting this far. Remember, I'm here to help, so don't be afraid to read through the explanations a few times to make sure things are really clear before you move on! 1. Match each word to its corresponding code using numbers that appear more than once: There are three codes with the number 6 in the first letter position. We have three words with P as the first letter. Therefore, 6 must be P (6 = P). The number 5 appears in the third and fourth letter positions in one code. The letter L is the third and fourth letters in the word PULL. Therefore, 5 must be L (5 = L). We now have enough information to match each word to a code, giving us: PAVE = 6241 SLIM = 3507 PULL = 6955 POLE = 6851 2. Work out what each letter is in code: So V = 4, I = 0, S = 3, U = 9, A = 2, L = 5 3. Work out the word: If we use this code on the word VISUAL, we get the answer of 403925.
  • Question 7

PERISH is your word this time, code cracker. Do you know what that means? It means to rot or decay. A perished, bruised apple is one of my least favourite snacks!

Here is a list of words:

Here are some codes for the above words. They are not necessarily in order:

7314  9251  0379  7279

Using this information, what would be the code for PERISH?

CORRECT ANSWER
041579
EDDIE SAYS
I hope your enthusiasm for number code cracking hasn't PERISHed yet, code cracker! Keep going - we can do it! Make sure you check your method against the explanation below: 1. Match each word to its corresponding code using numbers that appear more than once: The number 7 appears in the third letter position twice. The letter S appears in the third letter position twice Therefore, 7 must be S (7 = S). That was quick! We now have enough information to match each word to a code, giving us: SORE = 7314 HAIR = 9251 POSH = 0379 SASH = 7279 2. Work out what each letter is in code: So P = 0, E = 4, R = 1, I = 5, S = 7, H = 9 3. Work out the word: If we use this code on the word PERISH, we get the answer of 041579.
  • Question 8

Come on then, code cracker - only a few questions left! We can do this!

Here is a list of words:

PINE  DOVE  EARN  RAIN

Here are some codes for the above words. They are not necessarily in order:

9241  1803  6731  0873

Using this information, what would be the code for PROVIDE?

CORRECT ANSWER
6024791
EDDIE SAYS
Can you believe that you are already at question 8, code cracker? That's brilliant work! We still need to make sure we are practising our stage by stage approach all the way to the end, though. Read carefully...! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 1 in the fourth letter position. We have two words with E as the fourth letter. Therefore, 1 must be E (1 = E). The number 1 also appears in the first letter position in one code. Therefore, we know that the code for EARN is 1803 and so we now have enough information to match each word to a code, giving us: PINE = 6731 DOVE = 9241 EARN = 1803 RAIN = 0873 2. Work out what each letter is in code: So P = 6, R = 0, O = 2, V = 4, I = 7, D = 9, E = 1 3. Work out the word: If we use this code on the word PROVIDE, we get the answer of 6024791.
  • Question 9

EDIBLE food is generally the best food, wouldn't you agree code cracker?! Let's see if you can find the code...

Here is a list of words:

BLUE  DEAL  BLED  DIAL

Here are some codes for the above words. They are not necessarily in order:

7429  8904  8304  7498

Using this information, what would be the code for EDIBLE?

CORRECT ANSWER
983749
EDDIE SAYS
We are on the penultimate question! What brilliant progress you have made, code cracker! Remember, if you have found this a bit tricky, it's a great idea to go back and have another go at the worksheet. Keep practising that technique! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 4 in the fourth letter position. We have two words with L as the fourth letter. Therefore, 4 must be L (4 = L). The number 0 appears in the third letter position in two codes. The letter A is the third letter in two words. Therefore, A must be 0 (0 = A). The number 9 appears in the second, third and fourth letter positions. The letter E also appears in these positions in three words. Therefore, 9 is E (9 = E). We now have enough information to match each word to a code, giving us: BLUE = 7429 DIAL = 8304 BLED = 7498 DEAL = 8904 2. Work out what each letter is in code: So E = 9, D = 8, I = 3, B = 7, L = 4, E = 9 3. Work out the word: If we use this code on the word EDIBLE, we get the answer of 983749.
  • Question 10

There is nothing I like more in creative writing than a bit of alliteration: can you find the code for the movement of the slithery snake?!

Here is a list of words:

SOLE  TAIL  RUSH  LETS

Here are some codes for the above words. They are not necessarily in order:

9137  7491  3269  8270

Using this information, what would be the code for SLITHER?

CORRECT ANSWER
7963018
EDDIE SAYS
Slithery snakes! We've made it to question 10! That's awesome work, code cracker, you should feel really proud of yourself. Now, just make one last effort to check through the explanation carefully to make sure that you know how to get to the answer confidently. 1. Match each word to its corresponding code using numbers that appear more than once: There are three codes with the number 9 in the first, third and fourth letter positions. The letter L appears in these positions in three words. Therefore, 9 must be L (9 = L). That's all we need! We now have enough information to match each word to a code, giving us: SOLE = 7491 TAIL = 3269 RUSH = 8270 LETS = 9137 2. Work out what each letter is in code: So S = 7, L = 9, I = 6, T = 3, H = 0, E = 1, R = 8 3. Work out the word: If we use this code on the word SLITHER we get the answer of 7963018. That's it! Fantastic, code cracker!
