The Big Fat Maths Book

Last Friday the postman brought us three new books: Grote Taalboek, Grote Taalboek oefenboek and Grote Rekenboek oefenboek (two books for a Dutch language curriculum and a maths book). He didn’t even look at the Dutch curriculum book and was delirious about the maths book. He spent something like 5 hours doing maths that day.

The Adventure Continues

Have visited the awesome Continium science museum in Kerkrade (in the south of The Netherlands) for the second time and loved it again. We enjoy Continium much more than NEMO in Amsterdam because it’s not crowded (even during the Easter weekend) and there’re many more high tech interactive tools to learn from in a fun way. Simon particularly liked the magnetic gears and the windsail experiment (whether the number of windsails influences the amount of energy produced by the windmill)

Probability Calculations

Simon was practicing probability calculations this weekend – with coins, dice and Pascal’s triangle. What are the chances if throwing heads or tails with one, two or more coins? And how many combinations will you get throwing 2 dice? 36 or 21? And 3 dice? In the video Simon discusses the probabilities of getting heads once when throwing two coins and how many combinations he will get throwing 4 coins (2 to the power of 4) and more.

Kinetic (Sticky) Sand and Microchips

image

Kinetic sand is a great success for two days in a row, two days of vacuuming the whole apartment that is…  What is kinetic sand, Mom? It turns out that it’s 98 percent made of silicon dioxide, the same as sea sand. And what else is made of silicon? The Earth mantel and the microchips! And what are microchips?

This is how homeschooling is naturally propelled by simple things.
