Subject: Re: Teaching algebra in middle school
Hi Alice, It seems a good idea to start algebra as algebra in the middle school level. However it can be introduced in grades 4th or 5th while they learn multiplication and division. For example; If I add 6 marbles to my basket, I have 24 in all. How many did I have originally? - can also be introduced as I had x marbles in my bag. When I added 6 marbles, I had 24 marbles. How many did I have in the beginning? This can be made into an equationn as x+ 6 = 24, which leads to subtracting 6 from both sides to get the result. Or, if 30 oranges have to be given to 6 children, how many does each one get? This can be posed as: Let each one get x oranges, then 6 of them will get 6x oranges, which is equal to 30, and then this can be represented as x = 30/6, so that they get the idea of multiplication and division as opposite operations. While every sum need not be transformed, some of them can be shown as algebraic expressions. -Amba, for the T2T service
