Grade 3 Division by 10 Long Division Worksheet

OVERVIEW

Mastering division by 10 is a fundamental skill in third-grade mathematics. This specialized worksheet is designed to help students bridge the gap between basic division facts and more complex long division procedures. By focusing specifically on dividing three-digit multiples of ten by the number 10, students can begin to recognize patterns in place value and develop a faster mental math processing speed. This resource provides 20 structured problems that are perfect for daily warm-ups, homework assignments, or targeted classroom instruction. It reinforces the concept that dividing by ten is equivalent to shifting digits one place to the right, which is an essential building block for future work with decimals and percentages.

STEP-BY-STEP SOLVED EXAMPLES

To help your students get started, here are three solved examples from the worksheet using the standard long division approach.

Example 1: 920 ÷ 10

In this problem, we determine how many groups of 10 fit into 920. 1. First, see how many times 10 goes into 92. It goes 9 times (10 x 9 = 90). 2. Subtract 90 from 92 to get a remainder of 2. 3. Bring down the 0 to make the number 20. 4. 10 goes into 20 exactly 2 times (10 x 2 = 20). Final Answer: 92

Example 2: 450 ÷ 10

Using the "zero removal" trick for mental verification: 1. Identify the dividend: 450. 2. Since we are dividing by 10, we can simply drop the last zero. 3. 450 becomes 45. Final Answer: 45

Example 3: 640 ÷ 10

Looking at place value: 1. 640 is the same as 64 tens. 2. 64 tens divided by 10 equals 64 units. Final Answer: 64

TEACHER & PARENT TIPS

When teaching this worksheet, encourage students to look for the "pattern of tens." Show them how 730 becomes 73 and 500 becomes 50. Use base-ten blocks to visually demonstrate how grouping 730 units into sets of ten results in exactly 73 groups. This visual aid is crucial for tactile learners. For a challenge, have students time themselves to see how quickly they can complete the sheet using mental math before writing down the long division steps to verify their answers.
