  • Students multiply the numerator and denominator by the same number to write equivalent fractions.
  • Students explain why an equivalent fraction names the same amount.

How to use

Start with the pictures so students see each piece being cut again, then move to the number problems. Ask students to say the multiplier out loud for each one.

Mia's sub is cut into 3 equal pieces, and she eats 2. The chef then cuts every piece into 2 smaller pieces.

2/3 =  /6

2.
Carlos's sub has 4 equal pieces, and 3 are eaten. Then every piece is cut into smaller equal pieces.

Each piece was cut into how many smaller pieces?  
3/4 =  /12
