Dividing Decimals Worksheets – Tenths by Tenths
Teach decimal division by scaling both quantities together.
Teaching notes for parents and teachers
How to teach it
Show that measuring in smaller units changes both numbers by the same factor. Compare the original division with its whole-number-divisor form.
Example to work through together
Use the model below as you explain the example. Have your student point to the quantities as you discuss them.
Group six tenths into pairs. Each small section below represents one tenth. Each outlined pair has a total length of two tenths.
There are three groups of two tenths. Therefore 0.6 ÷ 0.2 = 3. The quotient counts the groups; it is not a length of three tenths. Check by putting the groups back together: 3 × 0.2 = 0.6.
Ask your student
Why does the number of groups stay the same?
If your student needs help
If the student moves only one decimal point, return to a concrete example using the original units.
Choosing and using the worksheet
Each set has eight problems. The dividend is positive and below 20; the divisor is positive and below 10. Both have one decimal place. Every quotient ends exactly at a whole number, tenths, or hundredths: no rounding is needed. This set does not include division by zero, repeating decimals, whole-number divisors, or answers requiring three decimal places. Use New numbers for a fresh set with the same scope.
Make a practice set
Select the worksheet, answer key, or both. When both are selected, the answer key prints after the questions. Keep it separate if you want your student to work independently.
After your student finishes
Multiply each quotient by its original divisor to check the dividend. Ask the child to explain why both numbers must be scaled together, and accept equivalent final-zero forms.
