you are amazing!! please stay in touch!!
I was sent an interesting article with tables that I posted on my blog showing the difference in number of math topics covered per year in the US vs. A+ countries (including Singapore). With the number of topics we throw at our kids per year in the US, it’s amazing that any of it ever sinks in! http://zerosumruler.wordpress.com/
I learned an awesome model today at an interview, of all places. The “as compared to” model for subtraction. Take “7 – 2”. This can be read as “7 as compared to 2”, which leads to an answer of “they are comparably 5 apart”.
It also works for subtracting negatives! “7 – -2” can be read as “7 as compared to -2”, which leads to an answer of 9 since 7 and -2 are comparably 9 spaces apart!
So awesome!
