What Your Child Will Learn
- Identify the value of digits in multi-digit numbers up to 10,000,000 and explain how place value determines each digit's worth
- Convert between standard form, expanded form, and word form for numbers containing up to seven digits with accuracy
- Compare and order multi-digit numbers using place value understanding, including numbers that differ in only one place value position
- Apply place value concepts to round large numbers to the nearest ten thousand, hundred thousand, and million
- Recognize and work with basic decimal place values (tenths and hundredths) as extensions of the base-ten system
How to Use This Worksheet
- Step 1: Review place value positions up to millions using a place value chart, having your child practice identifying what each position is called
- Step 2: Work through the first 3-4 problems together, demonstrating how to break large numbers into periods (groups of three digits) and read them systematically
- Step 3: Have your child complete 4-5 problems independently while you observe, checking their work and providing guidance on any errors in number reading or writing
- Step 4: Focus extra attention on expanded form and word form conversions, as these require students to truly understand what each digit represents in its position
- Step 5: Complete the remaining problems together, discussing any challenging concepts like rounding to large place values or basic decimal place identification
Tips for Parents & Teachers
Use a place value chart with columns labeled up to millions when working with large numbers - many students confuse hundred thousands with millions, so emphasize the comma placement and have them practice reading numbers aloud
When converting to word form, teach students to break numbers into groups of three digits (periods) and work left to right - common mistakes include writing 'five hundred thousand' as 500,000,000 instead of 500,000
For expanded form problems, encourage students to write out the actual place value (like 40,000) rather than just the digit and place name, as this reinforces the concept that the 4 in 43,567 represents four ten-thousands, not just 4
Introduce decimals by connecting them to money concepts students already know - explain that 0.25 is like 25 cents, helping them understand that decimal places continue the place value pattern to the right of the decimal point
Frequently Asked Questions
My child can read smaller numbers but struggles with numbers in the millions. How can I help them?
Break large numbers into chunks of three digits, separated by commas. Teach them to read each chunk followed by its period name (million, thousand, or nothing for ones). For example, 3,456,789 becomes 'three million, four hundred fifty-six thousand, seven hundred eighty-nine.'
What's the difference between expanded form and expanded notation that my 4th grader needs to know?
Expanded form shows the value of each digit added together (like 40,000 + 3,000 + 500 + 60 + 7), while expanded notation might use multiplication (4 × 10,000 + 3 × 1,000, etc.). At this level, focus on expanded form first as it more clearly shows place value concepts.
Why are decimals included in a 4th grade place value worksheet?
Fourth grade introduces basic decimal concepts as an extension of place value. Students learn that just as places to the left of ones are ten times bigger, places to the right are ten times smaller. Focus on tenths (0.1) and hundredths (0.01) only at this level.
My child confuses hundred thousands and millions when writing numbers. Any tips?
Use the comma as a visual cue. Numbers in hundred thousands have the comma after the hundreds place (like 500,000), while millions have a digit before that first comma (like 5,000,000). Practice with a place value chart that clearly shows the comma placement.
How can I help my child remember the order of place values for such large numbers?
Teach the pattern: ones, tens, hundreds repeats in each period. So it's ones-tens-hundreds, then thousand-ten thousand-hundred thousand, then million-ten million-hundred million. The pattern of 1-10-100 repeats every three places, just with different period names.
