Lesson 7

The purpose of this lesson is for students to find factors and multiples of a given whole number from 1–100.

In previous lessons, students learned about factor pairs, multiples, and prime and composite numbers.

The purpose of this lesson is for students to use the language of factors and multiples to describe numbers within 100. Students look for all factors of numbers and decide whether a given number is prime or composite. Students are encouraged to find patterns in composite numbers which help to identify a factor. For example, if the last digit of a number is 0 then 2, 5, and 10 are all factors of that number.

As you finish up this section, reflect on the norms and activities that have supported each student in learning math. How have you seen each student grow as a young mathematician throughout this work? How have you seen yourself grow as a teacher?
