Unit 1, Lesson 12
Toneladas y toneladas de basura (Optional)
Grado 5
Preparation
Lesson Narrative
This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling (MP4).
In previous lessons, students computed volumes. They packed unit cubes inside boxes and found the volume of the box by multiplying the side lengths of the box. In this lesson, they will investigate a real-world problem, using these ideas.
In the first activity, students find different arrangements of 60 shipping containers, assuming that they are cubes. While real shipping containers are not cubes, we can simplify the situation by working with figures that are easier to use. Students are asked to draw a diagram of one of their arrangements.
In the second activity, students estimate the number of shipping containers on a fully loaded cargo ship from a picture.
- Engagement
- MLR7
- Determine an estimate for volume in a real-world problem, and justify (orally and in writing) the estimate.
- Generate different figures composed of rectangular prisms with a given volume.
- Investiguemos lo que le pasa a la basura.
Required Materials
Required Preparation
- Each group of 2 students needs at least 20 connecting cubes.
Teacher Reflection Questions
Who got to do math today in class and how do you know? Identify the norms or routines that allowed those students to engage in mathematics. How can you adjust these norms and routines so all students do math tomorrow?
