Unit 2, Lesson 17
Imágenes de mosaicos (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 found products of whole numbers and fractions, including fractions greater than 1. In this lesson, they apply what they learned about multiplying whole numbers and fractions to make mosaic art pieces out of rectangles and they use the area of the pieces to estimate how much it costs to recreate the mosaic with hard material like stone, tile, and glass. Throughout the activity, students make sense of problems and persevere in solving them (MP4).
- Action and Expression
None
- Explain (orally and in writing) strategies for solving real-world area problems involving multiplication of whole numbers and fractions.
- Hagamos el diseño de un mosaico.
Required Materials
Activity 1
Required Preparation
- Each student needs a few sheets of the same colored paper.
- Each group of 4 needs a ruler, scissors, glue, and one large piece of chart paper.
Teacher Reflection Questions
How does connecting rectangles to art help students to engage with the mathematics of the unit?
