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.
