This activity is a fun way for students to practice money skills integrated with an opinion writing piece. This activity would work best after identifying and counting money has been taught and after students are familiar with writing opinion pieces.
When doing this activity, I purchase the items students use to decorate their cookie beforehand and have a "bakery" in our classroom. This activity has been a huge hit in my classroom! Students know they must use their counting money skills in order to create their cookie. It is a great motivator and helps solidify the concepts taught in a fun way.
