Lesson Plan

Measuring with Standard Units

Standards

Printable Aids

Teaching Notes

Guide students to use real-world referents for inches (e.g., thumb width, paperclip) and feet (e.g., ruler, adult foot) to aid in unit selection. Emphasize why an appropriate unit is chosen.

Vocabulary

Inches: A small unit of length.

Feet: A larger unit of length.

Common Mistakes

• Choosing inches for very long objects (e.g., car)
• Choosing feet for very short objects (e.g., crayon)
• Confusing relative sizes of inches and feet.

Differentiation

Discussion Questions

• What objects are best measured in inches?
• What objects are best measured in feet?
• Why is it important to choose the right unit?
• How many inches are in one foot?

Extension Activities

• Measure objects with both units.
• Convert between units.
• Estimate in feet and inches.

Parent Tip

Ask your child to choose the best unit (inch or foot) for measuring common items.
