Identifiquemos y clasifiquemos figuras
In previous grades, students identified, described, and compared two-dimensional and three-dimensional shapes. Students learned that shapes have defining attributes and drew shapes that possessed these attributes.
In this lesson, students learn that they can identify a shape by the number of sides and corners it has. Students sort shapes into examples and non-examples of triangles, quadrilaterals, pentagons, and hexagons. They define triangle, quadrilateral, pentagon, and hexagon based on the number of sides and corners and use these terms to name shapes. Throughout the lesson, students have opportunities to think about how to clearly describe the attributes of shapes to others and consider the precision of their language (MP6). It is not necessary for students to use the term vertices, so they are referred to as “corners” in this unit.
- Recognize triangles, quadrilaterals, pentagons, and hexagons based on the number of sides and vertices (corners).
- Clasifiquemos y nombremos figuras según sus lados y esquinas.
