I've been in a debate these last few days over multiplication tables. How do you teach them. I've heard from a number of people who say that they need to be memorized. My problem with this is that only a handful of students seem capable of doing this and with less time being spent studying at home this numbeer is getting smaller.
Students who are not successful in memorization are lost when memory fails. The student who forgets 4 x 6 makes no effort to solve this problem. He has failed.
I think that students need to be taught to recognize patterns. Then, when memory fails the real math begins.
"I don't know 4 x6 but 2 x 6 is 12 so if I double 12.."
" I don't know 4 x 6 but I know you can halve and double so 4 x6 is the same as 2 x 12 or 3 x 8 ."

I'm subbing 2 days for a grade5/6 class next week. The class is doing number patterns in math and I was looking for something fun to do with fibonacci numbers. Most online activities say the numbers are 1 1 2 3 5 8 13 21 etc. and they are very common in nature. Go out and find them. I spend a lot of time outdoors and I know a lot of plants like clover have 3 leaves and many flowers have 5 petals but there are a lot of plants out there that don't seem to fit.I think it may be interesting to us some cube links or other blocks to build a pattern. We can use calculators to divide. 5/8 = 0.625 8/13 = etc. Has anybody done anything with these numbers ?
I have a number of science demos that I like to do with elementary students. Some require a little practice or prep time but you soon become confident with them.
I have never had a problem with this demo and have done it dozens of times but I still expect the glasses to go crashing to the floor.
We begin with a discussion of Sir Isaac Newton. There always seems to be one or two students who claim to have heard of him . I have been scared to ask how or where. I talk a little about gravity and the Law of Inertia.
