# Friday Challenge: 26th June

## Play a Maths Game!

Make a pile of digit cards numbered 1 to 9.

Player A takes one of the cards. e.g 3.

Ask the question, ‘Which card would you choose to go with the 3 so you could make the largest possible two-digit even number with the two cards?

Put the card back in the pile.

Player B takes a card. e.g. 6.

Ask the question, ‘Which card would you choose to go with the 6 so you could make the largest possible two-digit even number with the two cards?

Have a go at this with a partner. Take it in turns.

Try it several times so you are sure you have a good method. Talk about your ideas with your partner so you agree together on a 'best' method.

How would your strategy change if you had to make the largest two-digit odd number?

If you don't have a partner to work with, you could follow this link to an interactive activity.  The computer selects one digit at random. You must then choose a digit to make the largest possible two-digit even number or largest possible two-digit odd number.
