Number talks are short mathematical discussions between the student, teacher, and classmates about how to solve a carefully chosen mental math problem. The students share their mathematical reasoning as the teacher records their thinking visually on the board or chart paper.

Lead the class in a mathematical discussion using a number talk.

40 ÷ 4

16 ÷ 4

56 ÷ 4

These mental math problems will allow students to build on multiples of ten and find easy ways to divide within the dividend. This will help direct the students' thinking to use the partial quotients division strategy using the relationship between multiplication and division. Allow the students to share their thinking and mathematical reasoning to solve the problems.

Once students have had an opportunity to share their thinking using the number talk, allow students to answer the journal prompt to continue their mathematical reasoning on the relationship between multiplication and division.
