Division by 100

• When you divide a number by 100, the last 2 digit of the number will be the remainder

• The number formed by the remaining digits of the dividend is the quotient

Division by 1000

• When you divide a number by 1000, the last 3 digit of the number will be the remainder

Estimate Quotients

Using Compatible numbers

When choosing an estimation technique, choose one that uses numbers that are easy to compute mentally.

​

​Use compatible numbers - numbers that are easy to compute

​

​120 and 6 are compatible numbers --- 120÷6=20

If using rounding: 132÷6 --- 100÷6, which is not easy to divide mentally by 6.​

​Yes; 700 is close to 720, and 720 ÷ 8 = 90 rubber bands per ball.
