Hi Baby Mathsters!
I think a lot of people (myself included) have been wondering what exactly the difference is between the Doman and Shichida methods.
Thanks Agnes for sharing the Shichida lesson schedule with us - without you, it would have remained a mystery to many of us!
I have made a document comparing the Doman and Shichida schedules, as far as quantity and equation lessons go (see attached).
It shows the weeks/days and how many quantities/equations per day. For Shichida, the no. of equations per day varies, so you will see something like "(x7-10)." This means you do between 7 and 10 equations per day.
If anyone spots anything incorrect in this document, do let me know!
(NB There are times when Doman is not that specific about how long to spend on something. I've set aside 3 weeks whenever he said "a few weeks.")
I have some questions about the Shichida method - wonder if anyone can help clarify the following...?
1. How many lessons are there per day with Shichida?
2. Do you show the same equations more than once per day?
3. You show addition/multiplication for 10 days, but subtraction/division for only 5. Is this because it's easier to grasp subtraction after addition, and division after multiplication (they being the opposites of each other)?
4. Why do you have a different number of equations on different days?
5. Mixed + and – equations are not followed by mixed x and / equations. Is this because three-step multiplication and division are considered more difficult than three-step addition and subtraction? (This is not something I could imagine Doman ever admitting to. He would probably say that if a calculator can do multiplication as quickly as it can addition, then so should our superior human brain!)
Soon there could be no more Shichida Math Mysteries left! Here's hoping anyway...
