It isn’t actually 20% of allotted time for Grade 8 Mathematics, more like 17%. Close enough when not dealing with NASA type accuracy.
There has been a lot of discussion about The Khan Academy. It’s made some people very happy and some people sound quite vexed. I personally like it. Is it what is fascinating and wonderful about mathematics? No. Does it help some of our kids progress with skills? Yes, it does.
My grade 8s have the joy of Mathematics five times every fortnight, every Tuesday and Friday an alternating Wednesdays. The Wednesday lessons are slightly shorter than the others. After we finished our unit on Statistics and Linear Equations we then looked at the Mathematics they had been applying to their investigations in its simplest or purest (abstract) forms. They had been successfully applying it, but it then posed a challenge for some when it lacked a context. Quite interesting to go the other way. It is at this point where I like to give students a chance to fine tune their algebraic skills so that they are ready for high school Mathematics and Science. Not just a few lessons, but a regular time in classes to work on their skills, particularly algebra. This is where Algebra on Demand came from.
Every Wednesday my Grade 8s take a break from their unit, currently Probability, and do what they need to. The original plan was the Khan Academy, but this has changed in a very exciting way. It was the students who led me there.
Now my students choose what they do:
- Khan Academy for skill mastery. Some of my students have their parents and tutors as coaches. Some parents have even joined in.
- Work from other schools. Our Korean and Japanese students often have extra Mathematics, needed for entry into schools back home.
- Interesting Student Led Investigations. These students started using Khan for Mathematics beyond our Grade 8 curriculum. This led to them asking questions which lead to investigations purely out of interest. That’s a win! I don’t ask for written reports. Sitting with them, seeing what they have found and discussing the Mathematics is feedback enough that they are pushing themselves further. Why take the fun away?
