Introduction
(5 minutes)
Write the number 12 on the board.
Ask students to shout out factors (i.e., "What numbers go into 12?").
Write the factors around the number and prompt students as needed to get all factors (1, 2, 3, 4, 6, 12).
Explain, "These are all factors of 12. Factors are numbers we can multiply together to get another number. For example, 3 x 4 is 12, so 3 and 4 are both factors of 12."
Write the definition of "factor" on the board (a whole number that divides exactly into another number).
Beginning
Give students thinking time to discuss the factors of 12 with a partner before shouting them out as a whole group.
Intermediate
Include the meaning of "factor" in students' home language (L1) as applicable.
Display examples of factors to help solidify understanding.
