Another Math Find

CH picked this up on her own and I discovered later that it is another good book for Peg Memory, although it is much more challenging as the numbers are not printed. You'd need to count and remember the answer.

The basic use of the book as suggested by the author is learning to find each sum without counting one by one. It is a fun way to reinforce Math concepts. Every page presents a challenge, introducing children to creative problem solving. I certainly appreciate the answers given on the back pages, whilst the rhyming riddles make reading enjoyable too!

One of the pages goes like this:

Mama mia, pizza pie,
How many mushrooms do you spy?
Please don't count them, it's too slow,
This hot pie was made to go!
Let me give you some advice,
Just do half and count it twice.

The 'problem sum' comes up at the end of each riddle and young children can learn about 'half', 'twice', 'repeat', 'match', 'groups of...' etc.

SW and I were having a ball of a time, hysterically trying to recall from the first answer after every new one we add up when I caught sight of CH watching us, her jaw dropping. I suspect she did not quite know what we were doing.
