Introduction
(2 minutes)- Present students with a word problem: "I love to bake and I need to make two cakes for my friend's birthday party. A recipe calls for 3/4 cup of sugar and I want to double the recipe. How many cups of sugar do I need?"
- Give students a minute of thinking time before they verbally share with a partner how they would solve this problem (some students may add 3/4 + 3/4, while others might think of multiplying the whole number 2 by 3/4).
- Invite students to share their solutions with the whole class and record their responses on the board.
- Validate students' answers and explain that today they will practice creating word problems to go with math equations that involve multiplying a whole number and a fraction.
