M3.2.4 For the adult
Short division
How do I divide 5 217 by 7 on paper?
What this chapter teaches
Short division works from the left, one digit at a time, and carries each leftover to the next place. The last leftover is the remainder, which can be written as r or as the remainder over the divisor.
Three questions to ask
There is no one right wording. Listen for the idea.
- Why does short division start from the left?
- In 5 217 ÷ 7, where does the carried 5 go, and why?
- How can you write the remainder 2 in 5 217 ÷ 7 as a fraction?
After the chapter, the learner can
- Divide a 4 digit number by a 1 digit number
- Write a remainder as a whole number or as a fraction
What they copy into their notebook
Divisor outside, number inside. Start at the left. See how many times the divisor goes into each number. Write it above, and carry what is left over. The last leftover is the remainder.
