### Worms

Place this "worm" on the 100 square and find the total of the four squares it covers. Keeping its head in the same place, what other totals can you make?

### Which Scripts?

There are six numbers written in five different scripts. Can you sort out which is which?

### Highest and Lowest

Put operations signs between the numbers 3 4 5 6 to make the highest possible number and lowest possible number.

# Various Venns

##### Stage: 2 Challenge Level:

Cong from St Peter's Roman Catholic Primary School sent in solutions to both parts of this problem. Cong sent us pictures of his completed Venn diagrams. Here is the first:

And here is the second:

I am interested in where you have placed zero in both Venn diagrams, Cong. It is difficult to say whether 0 is odd or even - I can see why you have placed it as an even number, though, as it seems to extend the pattern $8, 6, 4, 2, ... 0$. It's easy to forget that $0$ is a square number - but certainly $0 \times 0=0$.

Michael from Kings Elementary School explained a bit how he went about filling in the first Venn diagram. Michael assumes that 0 is not a square number:

In order to find the solution to this problem you first need to list the squares which are $49, 36, 25, 16, 9, 4$ and $1$. There are $4$ odd square numbers which are $49, 25, 9$, and $1$. So you put the rest of the squares in the square numbers and odd numbers in the odd section and anything else you don't do anything with it.

Well done! Eliza, from Danebank School, also left $0$ out of the Venn diagram. What do you think? Is $0$ square and even?
