Daddy writes (Numberjacks and mathematics skill – update)

December 21, 2007

This is a note from Pippy’s dad, again, in praise of Chris and the team at OpenMind for Numberjacks.

Some years ago (from 1989-1992), I had the good fortune to be accepted to Balliol College, Oxford, to do a degree in Mathematics and Computation.

Dr. Frances Kirwan (who later became president of the London Mathematical Society) was one of my tutors. While I was an undergraduate, Frances had one of her children, who is now at Cambridge (reading Mathematics.)

Anyway, I recently went to a mathematicians reunion dinner at Balliol, and met up with Frances again, and inevitably the subject of mathematical literacy in children came up. I mentioned Pippy’s comment at age 4 “A prime number that’s a square number? Ridiculous”, and Frances was both amused and highly impressed at a child that young being aware of the concepts, so I explained about Numberjacks.

FACT: Pippy learnt about square numbers from Numberjacks.

FACT: Pippy was motivated by Numberjacks to play with buddy blocks, and make square, and what she then dubbed “rectangular” and “tricky” numbers. “Rectangular numbers” is a term with an obvious meaning to anyone who understands “square numbers”. “Tricky numbers” turned out to mean “prime”, which is the word I then supplied to her.

I have no idea whether Pippy will be interested in mathematics by the time she gets to University age (or, for that matter, have no idea whether she’ll even want to go to University), but having a conceptual grounding at age 4 that good?

Thank you so much, Mr. Ellis!

A nativity card

December 21, 2007

2007 Christmas card.jpgThis year, I found a nativity play card. It has a star, and Mary holding Jesus, and the moon or sun behind her.

Daddy says it’s actually called a halo, which is a light round someone’s head.

The card is green and blue, and I’m a bit surprised that it has green and blue on it.

The first day of Christmas

Christmas Tree 2007.JPG

Today is the first day of Christmas. Every year on the first of December, we put up our Christmas tree.

We had forgotten that the lights broke last year, so we bought new ones. We bought an extra set to decorate my room.

I chose the holly lights, which we put on the Christmas tree, and the multicoloured ones which we are about to put in my bedroom.

Daddy took a picture of the Christmas tree. (His camera flashed right in my eyes right as I was trying to sleep under the tree like Clara in the story The Nutcracker.)
