### QUESTION 1 of 10

Hi there code cracker!

Today we are going to learn about a new type of code.

This time, our codes will be turning words into numbers.

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.

In this activity, you will be a code cracker and work out the digit-based code for a given word.

It can be really helpful to write the words out and then write the corresponding numbers above each letter as you work them out.  Give it a go!

Let’s get started!

7160
EDDIE SAYS
This technique isn't always easy, so don't worry if it takes some time to get it right. Make sure you spend time going through the explanation to help you! 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 second and third letter positions. We have two words with O as the second and third letters. Therefore, 1 must be O (1 = O). The number 0 appears in the third and first letter positions in two words. The letter N is the third and first letter of two words. Therefore, 0 is N (0 = N). We now have enough information to match each word to a code, giving us: TOOK = 7114 WANE = 6309 NOOK = 0114 WADE = 6329 2. Work out what each letter is in code: So T = 7, O = 1, W = 6, N = 0 3. Work out the word: If we use this code on the word TOWN, we get the answer of 7160.
• Question 2

34628
EDDIE SAYS
Are you ready to wear the number code cracking CROWN, code cracker? Don't worry if not - we're still learning! Follow the stages carefully to help you get to the answer. 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 3 in the first letter position. We have two words with C as the first letter. Therefore, 3 must be C (3 = C). The number 4 appears twice in the second letter position in two words. The letter R is the second letter in two words. Therefore, 4 is R (4 = R). We now have enough information to match each word to a code, giving us: CROW = 3462 WORK = 2647 NEWT = 8125 CREW = 3412 2. Work out what each letter is in code: So C = 3, R = 4, O = 6, W = 2, N = 8 3. Work out the word: If we use this code on the word CROWN, we get the answer of 34628.
• Question 3

It's time to work out another code, code cracker. This time for STEW. I hope you're hungry!

EDDIE SAYS
How are you getting on, code cracker? Don't worry if you haven't quite mastered things yet - make sure you break the code a task at a time and use the explanation below to help you. I'm here to help! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 6 in the first letter position. We have two words with W as the first letter. Therefore, 6 must be W (6 = W). The number 5 appears in the last letter position in two codes. The letter Y appears at the end of two words. Therefore, 5 must be Y (5 = Y). We now have enough information to match each word to a code, giving us: WIN = 632 NEW = 246 STY = 915 WHY = 605 2. Work out what each letter is in code: So S = 9, T = 1, E = 4, W = 6 3. Work out the word: If we use this code on the word STEW, we get the answer of 9146.

EDDIE SAYS
Did you get the MICE their code? Even if you didn't get it first time round, I know you can do it. The key is to go through the explanation a few times, stage by stage, to clear up any confusion! 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 second letter position. We have two words with C as the second letter. Therefore, 4 must be C (4 = C). The number 9 appears in the third letter position in two codes. The letter E is the third letter in two words. Therefore, 9 must be E (9 = E). We now have enough information to match each word to a code, giving us: CAB = 421 MOB = 361 ICE = 049 ACE = 249 2. Work out what each letter is in code: So M = 3, I = 0, C = 4, E = 9 3. Work out the word: If we use this code on the word MICE, we get the answer of 3049.

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

143  341  941  359

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

3519
EDDIE SAYS
Did you work it out, code cracker? Definitely make sure that you write down each word and write the corresponding code above it when you work it out. This will really help you work out the number code for each letter. 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 3 in the first letter position. We have two words with S as the first letter. Therefore, 3 must be S (3 = S). That's all we need! We now have enough information to match each word to a code, giving us: SAG = 341 NAG = 941 SIN = 359 GAS = 143 2. Work out what each letter is in code: So S = 3, I = 5, G = 1, N= 9 3. Work out the word: If we use this code on the word SIGN, we get the answer of 3519.
• Question 6

4261
EDDIE SAYS
Are you getting the hang of this, code cracker? Remember: practice ensures progress. What could be more fun than practising number code worksheets at EdPlace?! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 6 in the first letter position. We have two words with M as the first letter. Therefore, 6 must be M (6 = M). That's all we need... again! Keep it simple when you can! We now have enough information to match each word to a code, giving us: MANE = 6241 MIKE = 6731 KITE = 3791 AIMS = 2760 2. Work out what each letter is in code: So N = 4, A = 2, M = 6, E = 1 3. Work out the word: If we use this code on the word NAME, we get the answer of 4261.

EDDIE SAYS
Are you on number code cracking FIRE, code cracker?! I reckon you are definitely getting there and you have made some fantastic progress so far. The fact that we've got to question 7 proves that! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 3 in the first letter position. We have two words with F as the first letter. Therefore, 3 must be F (3 = F). The number 2 appears in the second letter position twice. The letter A appears as the second letter twice. Therefore, 2 must be A (2 = A). We now have enough information to match each word to a code, giving us: FOG = 317 FAR = 326 IRE = 964 RAT = 628 2. Work out what each letter is in code: So F = 3, I = 9, R = 6, E = 4 3. Work out the word: If we use this code on the word FIRE, we get the answer of 3964..

EDDIE SAYS
How did you get on, code cracker? Remember to take it nice and slow - it is all about learning and mastering the skill at this stage! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 2 in the second letter position. We have two words with P as the second letter. Therefore, 2 must be P (2 = P). The number 1 appears in the last letter position in two codes. The letter E appears at the end of APE and RYE. Therefore, 1 must be E (1 = E). We now have enough information to match each word to a code, giving us: SPY = 924 APE = 321 CAR = 637 RYE = 741 2. Work out what each letter is in code: So S = 9, P = 2, A = 3, C = 6, E = 1 3. Work out the word: If we use this code on the word SPACE, we get the answer of 92361.

61742
EDDIE SAYS
Did you manage to read between the LINES and work out the code? Remember to use the different stages of the technique just as I do in the explanation below, code cracker! 1. Match each word to its corresponding code using numbers that appear more than once: There are two codes with the number 7 in the third letter position. We have two words with N as the third letter. Therefore, 7 must be N (7 = N). This is another speedy one - that's all we need! We now have enough information to match each word to a code, giving us: LIE = 614 NEW = 743 SON = 297 WON = 397 2. Work out what each letter is in code: So L = 6, I = 1, N = 7, E = 4, S = 2 3. Work out the word: If we use this code on the word LINES, we get the answer of 61742.
