Unit 8, Lesson 8
Día de centros sobre la multiplicación
Grado 3
Preparation
Lesson Narrative
Throughout the course, students have worked to develop fluency with multiplication and division within 100. In this lesson, they reflect on their progress and ways to improve their fluency with products within 100.
Students sort multiplication facts into groups, based on whether they know them right away, can find them quickly, or don’t know them yet. They then consider strategies for finding the value of unfamiliar products efficiently and practice applying those strategies.
At the end of the year, grade 3 students are expected to fluently multiply and divide within 100 and to know from memory all products of two single-digit numbers.
If students need additional support with the concepts in this lesson, refer back to Unit 1, Section B in the curriculum materials.
