Whole pieces of paper (one per student)
Scissors
Ruler
Markers or colored pencils
Chart paper for visual aids (optional)
Introduction (10 minutes): Explain the concept of decimal place value. Discuss how each place to the right of the decimal point is ten times smaller than the place before it (e.g., tenths, hundredths, thousandths).
Demonstration (10 minutes): Show a whole piece of paper to the class. Explain that this represents 1 whole.
Cutting into Tenths (10 minutes):
Have students fold and cut their whole piece of paper into ten equal pieces. Each piece now represents one-tenth (0.1) of the whole.
Discuss and show that each one-tenth piece is ten times smaller than the whole piece of paper.
Cutting into Hundredths (10 minutes):
Instruct students to take one of their one-tenth pieces and cut it into ten smaller equal pieces. Each of these new pieces represents one-hundredth (0.01) of the whole.
Highlight that these one-hundredth pieces are ten times smaller than the one-tenth pieces.
Cutting into Thousandths (10 minutes):
Have students take one of the one-hundredth pieces and cut it into ten even smaller pieces. Each of these pieces represents one-thousandth (0.001) of the whole.
Emphasize that these one-thousandth pieces are ten times smaller than the one-hundredth pieces.
Visualization and Comparison (10 minutes):
Allow students to compare the sizes of the whole, one-tenth, one-hundredth, and one-thousandth pieces.
Discuss how each place value is visually and physically smaller as they move to the right in the decimal system.
Reflection and Discussion (10 minutes):
Engage students in a discussion about what they learned. Ask questions like: “How did the sizes of the pieces change as we moved to the right?” and “Why is it important to understand decimal place value?”
Summarize the activity and reinforce the concept that each place value in a decimal is ten times smaller than the one before it.
