To find the biggest, look at each one in turn and remember the biggest so far.
To find the biggest, look at each one in turn. Bo can only peek at one tower at a time.
Bo keeps the biggest so far in his memory box.
Each time he asks one question: is this tower bigger than the box? If yes, swap it in. If not, the box stays the same.
When you run out of towers, the one in the box is the biggest.
These are some of the questions on the sets. The printable sheets have more and an answer key.
Swap. Twelve is bigger than nine.
Keep. Five is smaller than twelve.
7. 3, then 7, and 4 is smaller, so the box keeps 7.
No. The last tower is not always the biggest.
6. Two is smaller than six, so the box keeps six.
Ask a grown-up to lay six number cards face down. Turn them over one at a time. Keep only one card in your hand, the biggest so far, and swap it when you find a bigger one. At the end, say which is the biggest, then turn them all over to check!
Play the Mission: lay six number cards face down. Your child turns them over one at a time, keeping only one card in hand, the biggest so far, and swapping it when a bigger one comes. At the end, they say which is the biggest, then you turn them all over to check.
