• Framework: Montessori
• Unit: Mathematics
• Learning area: Fractions
• Level: Ages 5-6

Objectives

• Learn proper fraction vocabulary
• Name numerator and denominator
• Read and write fraction notation

Materials

• Fraction circles
• Fraction vocabulary cards
• Fraction writing practice sheets
• Red and blue pencils

Instructions

1. Present 3/4 with fraction circle. 2. 'The bottom number tells how many equal parts in the whole. This is the denominator: 4.' 3. 'The top number tells how many parts we have. This is the numerator: 3.' 4. Write fraction. Color numerator red, denominator blue. 5. Practice naming parts of various fractions. 6. Read fractions aloud.

Educator tip

Etymology helps: denominator means 'namer' (names the type of part), numerator means 'counter' (counts the parts).
