This Excel
file just lightens the computation burden for division,
allowing the teacher and student to discuss the process and explore
the relationships between the process elements.
Some terms: the Dividend (quantity to be divided) is divided by the
Divisor to produce a Quotient with possibly a Remainder.
Personally, I like to have some investigative activity somewhere in
the mix, whatever I'm teaching.
Here's a few starter ideas for division (clearly depending on the
level of your students):
You may wish to draw attention to the change in remainder as
the dividend increases in steps of 1 or in divisor-size steps.
For a specific divisor, ask students for a dividend that gives
a specific remainder. For example: ask students to choose a
dividend between 210 and 220, which when divided by 6, gives a
remainder of 3.
For divisors of 3, and also of 9, invite students to notice a
connection between the dividend's digit sum (the sum of the digits
in the dividend) and the remainder. And then to account for the
relationship observed.
