This math chapter workbook on "Whole Numbers" reviews place value to help students comprehend numbers and how each digit's position impacts its value. For example, one problem might tell the student to start with 435,431 and round that to the nearest thousand. Then, the student will be asked to add two to ten thousand. By rounding 435,431 to 435,000, students practice identifying which digit influences the rounding and why. Next, the problem introduces basic addition with larger place values, instructing students to add ten thousand (20,000) to the rounded number. This step reinforces their understanding of place value and addition.

Students will also learn decimal place values and must understand the difference between "hundreds" and "hundredths." To teach fifth graders about decimal place values and the difference between "hundreds" and "hundredths," a teacher can use visual aids and hands-on activities. Start with a place value chart, labeling each position (ones, tens, hundreds, tenths, hundredths), and use physical objects like base-ten blocks to represent whole numbers and decimals. Use relatable analogies, such as money-comparing $100 bills to dimes-and allow students to practice by placing different numbers on the chart.
