Find a great variety of ways of asking questions which make 8.
Choose any three by three square of dates on a calendar page.
Circle any number on the top row, put a line through the other
numbers that are in the same row and column as your circled number.
Repeat this for a number of your choice from the second row. You
should now have just one number left on the bottom row, circle it.
Find the total for the three numbers circled. Compare this total
with the number in the centre of the square. What do you find? Can
you explain why this happens?
For this challenge, you'll need to play Got It! Can you explain the
strategy for winning this game with any target?

It is hardest to get $12$ and negative $12$. You are most likely
to get the low positive and negative numbers. You are least likely
to get the high positive and negative numbers.

Then you can see that getting a $3$ or $-3$ are most likely to
happen. So you should place a counter near the $3$ or $-3$ because
then you are most likely to get it next turn, and then you will
have two in a row.
Very well noticed by everyone. Can anyone add
