Worksheet Overview

QUESTION 1 of 10

Letter detective, we need your help!  In this activity, we will be using the alphabet to help us crack a letter code!

 

Here is the alphabet for you to use as a reference:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

 

Now look at the following letter sequence:

 

AD is to DG as GJ is to ___.

?First, we have to work out how the first letter of the first pair A(AD) gets to the first letter of the second pair to the letter D(DG).

To get from A to D, we jump 3 places to the right.

Then we have to work out how the second letter of the first pair gets to the second letter of the second pair.

To get from D to G, we also jump 3 places to the right.

This means we need to do the same to the letters G and J to work out the missing letters in our sequence.

This means our missing pair of letters is JM.

 

So the answer is:

AD is to DG as GJ is to JM.

 

Let’s try another:

DF is to HJ as PR is to ___.

 

First, we have to work out how the first letter of the first pair (DF) gets to the first letter of the second pair (HJ).

To get from D to H, we jump 4 places to the right.

Then we have to work out how the second letter of the first pair gets to the second letter of the second pair.

To get from F to J, we also jump 4 places to the right.

This means we need to do the same to the letters P and R to work out the missing letters in our sequence.

This makes our missing letters TV.

 

In this activity, you will need to be a sequence superstar and complete the letter pairs.

 

 

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

Remember to use the alphabet line to help you work out the code.

CORRECT ANSWER
A
EDDIE SAYS
Welcome, detective! For this first one, each sequence follows the order of the alphabet going backwards, with one jump each time.
If you want to, you can follow the alphabet chart backwards by taking steps to the left. You can also follow the alphabet backwards in your head. One jump backwards from B is A.
  • Question 2

Here are two letter sequences that both follow the same pattern:

 

 M is to K as H is to ______ ?

 

Use your detective skills to find the missing letter in the second pair.

CORRECT ANSWER
F
EDDIE SAYS
How did you get on? Each sequence follows the order of the alphabet going backwards, with two jumps each time. So, two backwards from H is F.
  • Question 3

Here are two letter sequences that both follow the same pattern:

E is to A as S is to _____ ?

 

Use your detective skills to find the missing letter in the second pair.

CORRECT ANSWER
O
EDDIE SAYS
Getting the hang of it? Both sequences follows the order of the alphabet going backwards, with four jumps each time. Four jumps back from S is O.

CORRECT ANSWER
R
EDDIE SAYS
This time the sequences follow the order of the alphabet going forwards, with five jumps each time. Five jumps after M is R.
Remember that some questions can follow a forwards sequence, whilst others a backwards sequence. So keep your eyes peeled to spot which it is!

D
EDDIE SAYS
Backwards again! Both sequences follow the order of the alphabet going backwards, with six jumps each time. Six jumps back from J is D.
You're doing some sensational letter spotting!

EDDIE SAYS
Wow! You're whizzing through these questions! Great detective work.
Both sequences follow the order of the alphabet going backwards, with ten jumps each time. Ten jumps back from L is B.

CORRECT ANSWER
W
EDDIE SAYS
How are you doing detective? Both sequences follow the order of the alphabet going forwards, with twelve jumps each time. So twelve jumps after K is W.
Remember that if you reach the end of the alphabet when working out a sequence then just head right back to the beginning to continue.
  • Question 8

Did you keep up with the jumps?! Both sequences follow the order of the alphabet going backwards, with fifteen jumps each time. Fifteen jumps back from X is I. Fantastic!

A  B  C  D  E  F  G  H  I  J  K  L  M  N  O  P  Q  R  S  T  U  V  W  X  Y  Z
CORRECT ANSWER
P
EDDIE SAYS
A bit of a tricky one! This sequence follows the order of the alphabet going backwards, with four jumps each time.
Remember if you reach the start of the alphabet whilst moving backwards then head back to the end of the alphabet and continue. This is the opposite to what you would do if you were following a forwards sequence, where you'd head back to the start of the alphabet instead.
So four steps back from T is P. Perfect!

Here are two letter sequences that both follow the same pattern:

 

L is to S as W is to ______ ?

 

Use your detective skills to find the missing letter in the second pair.

D
EDDIE SAYS
Both sequences follow the order of the alphabet going forwards, with seven jumps forwards each time. So seven jumps after W is D.
You've put in heaps of effort to work out the letter connections in this activity detective!
