Lesson 21
Rompecabezas de fichas geométricas (optional)
Lesson Purpose
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.
In previous lessons, students found different ways to use pattern blocks to compose the same shape. They also used their understanding of coins and their values to solve addition problems.
In the warm-up, students are introduced to the context of a pattern block puzzle and use mathematical language to compare how the shapes are composed. In Activity 1, they create and solve pattern block puzzles. In Activity 2, they solve addition problems involving money within the pattern block puzzles context.
