Lesson 4
Exploremos los bloques sólidos geométricos
Lesson Purpose
Lesson Narrative
Students share their thoughts and ideas about geoblocks during the Notice and Wonder routine and then try their ideas during free exploration. Students have an opportunity to explore the geoblocks before they are asked to use them to represent mathematical situations in later lessons. As students explore geoblocks, they likely will build objects. As you monitor, consider asking questions such as “¿Cuántos bloques sólidos geométricos usaron? ¿Cómo lo descubrieron? ¿Cómo decidieron qué bloques sólidos geométricos usar?” // “How many geoblocks did you use? How could you find out? How did you decide which geoblocks to use?” These questions help teachers learn more about each student.
The first few lessons in this section are intentionally shorter to allow students to learn the structure and routines of math lessons and to give teachers an opportunity to learn what students know about concepts of number. If there is extra time, students may spend more time exploring geoblocks in the second activity.
In the lesson synthesis, students practice saying the verbal count sequence to 10 in preparation for counting objects in an upcoming section. Add variety to the counting by adding movement. For example, students can count as they clap, stomp their feet, or jump.
Math Community
Tell students that, at the end of the lesson, they will be asked to identify specific actions from their “Doing Math” list (both teacher and student sections) that they personally experienced.
