Do you have lively and intelligent 8-12 year old children, nephews, nieces or grandchildren? Grandpa Mike's books are full of mathematical puzzles and tricks, but they also explain how they work, and challenge kids to create their own variations. Don't just keep them entertained - make them want to know more. No doubt they will enjoy impressing their friends, too.
Do you know how the Romans used to multiply numbers? Plenty of adults will enjoy these little books, too.
Maths should be fun. It's not always easy to make it that way in the schoolroom, but providing a bit of stimulation at home works wonders. Give your child a gift for life.
