Whole Numbers and Decimals
Understanding place value is the foundation of all number sense. These foldable organizers help students visualize how digits shift in value, how decimals relate to whole numbers, and how patterns in powers of ten make computation easier. Perfect for interactive notebooks and hands‑on math instruction.

Answer each question about whole number place value.
Answer each question about decimal place value.
Type the value of the underlined digit. For example, in 345 the underlined digit 4 has a value of 40.
Students assemble the foldable place value chart and store it in their notebooks. The tabs reveal example values, helping students visualize how digits shift when multiplied or divided by powers of ten.
Use the organizer to show how the ones place acts as the “bridge” between whole numbers and decimals. Students quickly see how each place is ten times larger than the one to its right.
Have students write numbers under the tabs and observe how the digits shift when multiplied or divided by 10, 100, or 1,000. This builds a strong foundation for exponents and scientific notation.
Store original foldables in page protectors inside a three‑ring binder. Keep extra copies behind each master. This makes it easy to grab materials during class and keeps all organizers in one place.
