Division
Using the principles of repeatedly subtraction based on a subtraction
[Hi Abacus Lesson 3]Existing an abacus calculation methods for division has been controversial because there are mathematical concepts. (Zeros place, digit calculation method to place number divided on an abacus, etc) Hiabacus got rid of the unnecessary elements of the existing how to do division and switched as a mathematical way.
[Hi Abacus Lesson 3]Division gets to know using the principles of repeatedly subtraction based on a subtraction. (Discusses various prints, learning principle problem', etc)
Learning Target
1 | Learn mathematical concepts that determine the number of digits in the quotient through the problem of shares to obtain places. |
2 | In case of vertical problems, it can be induced to understand the basic concepts of the division where the number of digits in the quotient determined by displaying a dotted line that separates each position by writing the answers. |
3 | In the 'Hiabacus problem', you can understand the relationship between multiplication and division by a checksum to themselves. |
4 | The abacus calculation methods for division in principles is no different from the way of school and you can learn school methods in 'learning principle section'. |
5 | Like multiplication, when learning each lesson, we induced not to be mechanical learning through the proper combination of problems in the last lesson. |
