Type c question(Mirror code question)

Post by kentishdad »

This is driving me mad!! I am sure it is related to the so called mirror sequence but i cannot seem to work it out

if HARD is IBSE

What does UFTU

I thought it was as simple as moving forwards once..but to my surprise the ansewer is TEST....How :(

I would also appreciate more examples/explanations on this type of questions.

Many thanks

you are going forward to code -- so to decode you go back one!

Dear Kentishdad

If HARD is IBSE

What does UFTU

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

I teach my children to do a first check to see if it is a mirror code. They look at the first letter of the code and word, in this case H and I are they mirrors no, because they are on the same side of the alphabet. Therefore proceed as normal [ if they were mirrors eg B and Y they MUST check another pair of letters before making the decision that is a mirror] This takes all of2/3 seconds.

As this not a mirror, the child will now uses a rule dependent on whether they are looking for a code or a word. In this case they are looking for a word, the rule therefore is moving from the code to word:

I to H = -1 therefore U – 1 = T
B to A = -1 therefore F – 1= E

and so on….

Mirrors are not the norm, but they do occur, I tell my children whenever they see long codes they MUST immediately put a mirror line in between the M and N, this then reminds them that one of them may be mirror.

MIRROR CODES

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

Immediately put a line between the M and N to signify the mirror.

If the code for ESTATE is VHGZGV

What is the code for HOUSE

Is it a mirror. Look at the first letter of the word and code are they mirrors = yes E is 5 in from the beginning of the alphabet and V is 5 in form the end. Must make a second check. Find a pair of letters that are obvious if possible. In this case A is obviously the mirror of Z.

Checks done. Proceed as mirror code.

What is the mirror of H = S
What is the mirror of O = L
What is the mirror of U= F
what is the mirror of S= H
What is the mirror of E= V

I teach my children to know the alphabet well. I explain that the mirror is between M and N ie 13 letters each side of the mirror. I also show them that E is the 5th letter from the left and V is the 5th letter from the right.

With this knowledge it makes it easier to find mirrors reasonably quickly.

If they are looking for mirror of P its 3 away from the mirror, 3 away from the other side of the mirror is K

If they are looking for the mirror of F, they know E is 5th, therefore F is 6th. they know V is 5th so the sixth is U.

If they are looking for the mirror of X then its 3 away from the right end so its pair is 3 away from the left end.= C

the ' alphabet arc' is quite a useful way of visualising where a letter comes in the alphabet.\Imagine a semi circle with m & n at the top, speeds

Dear YoYo123

I too use the alphabet arc during my intial lessons. I use alphabet fridge magnets, giving the child randomly individual letters in quick succession. At first they get the letters all mixed up but eventually become quite adept.

I also play games with the alphabet:

I tell them that E and V are the 5th letters from each end.

M is the 13 th [M for middle]

T is the 20th letter [T for Twenty]

I then ask them quickfire questions eg what is the sum of F and T, give the answer as a position and a letter.

What is the product of M and C

etc etc

Hi

Have you tried making an alphabet circle?

In excel, enter the alphabet in column 1.

Go to the tables and charts icon and click on doughnut.

An alphabet circle will be created.

This is a good tool for counting forward past Z, and counting backwards past A.

Regards

We have fun with making up rhymes for the mirror method and this really helps my children remember them e.g

Amazing Zebras
Blue Yatch

Infra Red

King Prawn

etc......


They can still remember them years after
