3rd Grade Divide by 3 Worksheet: Long Division Without Remainders
Dividing by 3 means sharing a number into three equal groups and counting how many land in each group. This 3rd grade divide by 3 worksheet gives six numbers from 9 to 33, labeled a to f. For each one, your child writes the quotient on the line. Then the long division goes in the grid below it, and none of the six has a remainder. Because every number is a multiple of 3, the answers come straight from the division facts. In the corner, a boy kicks a soccer ball, as on the pages for dividing by 1 and by 2. The second page is an answer key with every long division worked out.
Three equal groups
Sharing into three equal groups is the heart of dividing by 3. If 18 cookies go onto 3 plates, each plate gets 6 cookies, so 18 ÷ 3 = 6. You can check by adding the groups back together: 6 + 6 + 6 = 18.
All six numbers are multiples of 3, so the sharing always works out with no remainder. For example, item c shows that 9 shared by 3 gives 3 in each group.
About the long division
The page asks for the long division method. In the US standards, long division is a 4th grade skill, while division facts like these belong to 3rd grade. So if the layout is new for your child, start with the facts. Say the answer out loud first, and then show how the long division gives the same quotient.
In item f, 33 ÷ 3, your child shares 3 tens into 3 groups to get 1 ten. Next, 3 ones shared by 3 give 1 one, so the quotient is 11.
After the page: check together
First, compare each answer with the answer key on page two, and talk through any long division that went wrong. Next, ask for the matching multiplication: 8 × 3 = 24 proves that 24 ÷ 3 = 8. Finally, pick a multiple of 3 between 9 and 33 that is not on the page, such as 21, and let your child share it into three groups out loud.
