YEAR 6 - NUMERACY
AUTUMN TERM 2006
In addition to the planned Numeracy curriculum Year 6 pupils the children are given investigative challenges. See if you can crack the code:
This is an example of how Ilayda worked it out - she cracked the code in record time - WELL DONE!
CRACK THE CODE THE ANSWER A divided by A = F C divided by A = H G divided by A = A FH divided by A = D FI divided by A = I FE divided by A = C HF divided by A = B HD divided by A = E HB divided by A = G AJ divided by A = FJ 3 divided by 3 = 1 6 divided by 3 = 2 9 divided by 3 = 3 12 divided by 3 = 4 15 divided by 3 = 5 18 divided by 3 = 6 21 divided by 3 = 7 24 divided by 3 = 8 27 divided by 3 = 9 30 divided by 3 = 10
Ilayda's Answer............
First I looked at the letters really carefully. Then I realised that there were 3 sums that had only one letter and tried to work out what times table it was, because times is the inverse of divide.
After, I realised that it was the 3 times table. So by looking at the letters I worked it out.
This is another code that 6S tried to crack with a completely different set of numbers. This is how James did it - WELL DONE!
Crack The Code James Answer I divided by I = J HI divided by I = I ID divided by = JD GA divided by I = A FA divided by I = E JC divided by I = H AC divided by I = C JG divided by I = G AG divided by I = B HD divided by I = F James worked out that: I = 6 JD = 10 A = 4 E = 9 H = 3 C = 8 G = 2 B = 7 F = 5
James' answer: First I used the numbers that I already knew to find out what the rest were that I didn't know. Once you know some numbers it's easy. If there is a sum you don't know, skip it and find a sum with at least 2 letters you do know. I knew what J was first because a number divided by itself always = 1.
