Lesson 5-5
1-Digit Quotients

Essential Understanding: Some real-world quantities have a mathematical relationship; the value of one quantity can be found if you know the value of the other quantity. Patterns can sometimes be used to identify the relationship between quantities.

What are the steps for dividing by 2-digit numbers?

Estimate to help decide where to place the first digit in the quotient.

428 ÷ 64 is about 420 ÷ 70, or 6.

Divide the one. Multiply and subtract.
