Write Fractions from Numerator and Denominator (311)

Teaching Notes

This activity helps students connect the verbal understanding of numerator and denominator to their symbolic written form. Emphasize that the denominator tells how many equal parts make the whole, and the numerator tells how many parts are being considered.

Vocabulary

Numerator: The top number.

Denominator: The bottom number.

Common Mistakes

• Swapping numerator and denominator.
• Writing whole numbers instead of fractions (e.g., '1 and 2' instead of '1/2').
• Difficulty understanding fractions equal to one (e.g., 2/2).

Differentiation

Discussion Questions

• What does the top number (numerator) of a fraction tell us?
• What does the bottom number (denominator) of a fraction tell us?
• How is a fraction different from a whole number?
• What does it mean if the numerator is the same as the denominator?

Extension Activities

• Write fractions for word problems.
• Create fraction cards.
• Draw pictures for fractions.

Parent Tip

Ask your child to write fractions for things you have, like 2/3 cups of flour.
