Dividing w i th the �Big 7� (called this because the enclosure looks like a large 7)
Using the �Big 7� in division can be help ful because you can use LANDMARK NUMBERS to
solve your p r oblem . It is helpful to rem e mber th at, just like m u ltip licati on is repeated addition,
DIVISION IS REPE ATED S U B T RACTION .
Divisor � The num ber you are dividing by
Quotient � T h e answer
Dividend � The num ber you are dividing
Here are the steps to tak e when usin g the �Big 7 � :
1. Divide : Ask yourself, �What is the highest m u ltiple
of the diviso r tha t will g o into th e dividend ?�
Hint: Use L ANDM ARK NUM BERS: W ill it go in
10 tim es? 20 tim es? Etc.
2. Multiply
the num bers. W r ite the equation on the
outside of the �7� to help you keep track of your work.
3. Subtract the am ount .
4. Repeat this process until your rem a inder can no longer
be divided by the divisor.
5. Add up the num b ers of the groups you were able to divide.
This is your answer, or the quotient.
Notice how the divisor (6) is consistently written
as a factor on the outside of the �Big 7.�
