Number talk - Cups of flour

See also: number-talk-examples

Sourced from an example given in Lee & Yeo (2022) written as

Martin was making play dough. He added ¾ cup of flour to the bowl. Then he added another 3/6 cup. Is the total amount he used greater than or less than 1 cup? How much flour did he use?

Implementation ideas

• Reframe it for an older age group
• Use teaching cooking pizza as an example
• Frame it in the form of three-acts-of-a-mathematical-story?
