Lesson Planning

Day 1

Use short division to divide 3-digit and 4-digit numbers by single-digit numbers, including word problems.

Follow-up

Use base 10 equipment to show how to use short division to divide 3-digit and 4-digit numbers by single-digit numbers.

Day 2

Check-up

Use short division to divide 3-digit and 4-digit numbers by 2-digit numbers.

Follow-up

List multiples of the divisor to help students to use short division of 3-digit and 4-digit numbers by 2-digit numbers.

Day 3

Use division of whole numbers, then divide by 10 or 100 to divide numbers/measures with one or two decimal places by single-digit numbers, including one place decimals.

Follow-up

Use efficient grouping to divide whole numbers, then divide by 10 or 100 to divide numbers/measures with one or two decimal places by single-digit whole numbers.
