Reflection: Real World Applications What's a Gram? - Section 3: Student Practice


According to Math Practice 4: Model with Mathematics, students should be able to apply the mathematics they know to solve problems arising in everyday life. During this lesson, students were exposed to opportunities to apply and develop their understanding of fractions in a real-world application. Even though we have yet to teach our fraction unit, I try to encourage conversations and integrate small lessons about fractions anytime I can!  

In this video, you'll hear students grappling with the idea that a whole candy corn weighs more than a gram: Conversations about fractions. This leads them to a group conversation about fractions. Here, 1:4 + 1:4, students add 1/4 teaspoon + 1/4 teaspoon to get 2/8. I remind students that we don't add the bottom numbers when we add fractions. We only add the top numbers. Together, they realized that 1/4 + 1/4 = 2/4. Hopefully these real-world applications will help support students' understanding of fractions later on during our fraction unit.
