Math Fun with Summer Produce

Summer brings abundance of math toys. Who needs cheerios or marbles when you have fragrant, smooth, sweet, colorful delights to count, compare, measure and then gobble up. How many peas are there inside each green pea pod? Do all the pods from the same plant host the same number of peas?


Check it out yourself and make a bar plot to describe the distribution of peas in your snap pea pods.


Heirloom tomatoes: yellow, green, purple, red. What color is the sweetest? What is the sourest? Heirlooms are expensive, but their rare availability makes me splurge on them once or twice a year. This year I decided that our kids are big enough to be able to enjoy the tomatoes’ exquisite taste. We did heirloom tomato sampling and ran a contest.


We cut baby heirlooms into four little pieces. Each of us tried a few pieces of each color and ranked the colors by their sweetness (5 was the sweetest, 2 the most sour). Surprisingly, our opinions varied vastly. We created a chart and added all the ranks. Purple tomatoes were voted the sweetest, yellow – grimacingly sour. This chart is still hanging on our refrigerator to reinforce the memories. Kids loved the game and a week later suggested that we do the same with the canollis that a guest brought.


Plums: seductively purple, innocently yellow, confidently bright magenta. Their variety and colors can compete with a lipstick selection. Can you tell a plum type by its taste? Cut them into pieces, close your eyes and see if you can do better than chance (guessing correctly over 50% of the time for two types tasted in equal amounts, 33% for three etc 100%/n types)? Can you distinguish between plums by shape, with your eyes still closed?

How many large plums are there in a pound? How many little plums? How many little plums can you trade for one large plum?

Do larger plums always have a larger seed?
You can eat your fruits and veggies and do math in the same time.



Carrots:
What can you do, what can you do, what can you do with the carrots?
You can measure your height with them. 10 carrots tall?
You can count your bites while eating them. 9 bites?
You can imagine you are a Musketeer and fence with them.
Wait, you can even scratch your back or head with them.
And, for the finale, be adventurous and swallow them!

(inspired by “What can you do with a shoe?” by Beatrice de Regniers and Maurice Sendak)




P.S. Scientific studies show that kids brains take a reverse evolutionary zip during summer month and by September they are two months behind in math and reading. Check out this Math Resources page for more pointers to math-infused books and games.

Here is a great fruit puzzle to brainstorm as a family: Mess at the Marrakesh Market.

London Summer and some photos

Here are some photos from that gig a few weeks ago. That one where I nearly died of heat exhaustion and then managed to sustain a rather humiliating head injury. In the following photos you will witness the boiled look I was sporting that evening.

London bakes today. People in the office are pushing boundaries by wackily eating ice-lollies at their desks. Sometimes they pause between licks to make the obligatory hilarious comments about global warming.

This week I am going to go Belated Birthday Shopping with my Dad. I will try to steer him towards the pony shop, but if that fails I am going to settle for a microphone and P.A. As in public address, not a personal assistant. Actually, though, if I could combine the pony with the personal assistant I would really feel Id hit the jackpot. Then I could give it orders down my microphone. "Eat that hay!", or "Swish your tail!". Stuff like that.

Impish Sophie Sister was over from Paris this weekend, which was delightful. She stayed with me in Brixton, something I am very keen for her to do on a more regular basis.

Anyway, here are some pictures. Please remember that it was eighteen hundred degrees in there. I am not normally that neon.
