Students will be able to identify the least common multiple of two numbers.
Students will be able to identify and explain multiples and non-multiples of a whole number with peer support and sentence frames.
Ask students to think of different ways to count. Pose the following scenario: let's say you are on a field trip and you want to count the total number of students quickly before getting on a public bus. What are some ways you could count?
Have students turn to a partner and share their ideas. Call on a few students to share with the whole class. Ideas may include counting by 2s or 3s, or have students form into groups of 4 or 5 to count them by groups.
Record students' ideas on a piece of chart paper entitled "Ways to Count."
