Aha!
A real page from the bookMORE THAN ANOTHER WORKSHEET
Sometimes a drawing helps; sometimes an unexpected idea brings you closer to the answer. You do not have to know it straight away. Trying things out is part of the game.
Hat mysteries, secret codes, weighing puzzles, maps, and truth-teller and liar investigations.
A separate hints section and explained solutions. The answer will not jump out at you before you are ready.
A4 pages with room for your answers. Lovely in colour and usable in black and white too.
A TASTE OF THE ADVENTURE
Three real puzzles from the book.
Think first, then take a peek!
Three boxes contain only apples, only pears, and a mixture of apples and pears. Their labels read “apples”, “pears” and “mixed”, but all three labels are wrong. You may take one fruit, without looking, from just one box. Which box do you choose, and how can you work out the contents of all three boxes?
A bat and a ball cost 110 tokens together. The bat costs 100 tokens more than the ball. How much does each cost? Check both their sum and their difference.
Draw four connected straight line segments through all nine dots without lifting your pencil. You may pass through a dot more than once, but every dot must be touched at least once. The lines may extend beyond the square formed by the dots.
And that is just 3 out of 165. Ready for the rest?
