Introduction
(4 minutes)- Ask students to turn to a partner and share their background knowledge on multiplication. Ask the following guiding questions to spark conversation: "What does multiplication mean? When do you need to multiply numbers? How do we show or represent multiplication?"
- Listen in on students' conversations and have them share with the whole group some of their key points. Guide students to the understanding that multiplication is when you add a number to itself a certain number of times. Some ways we can show multiplication include arrays, repeated addition, equal groups of items, a multiplication chart, etc. Record students' ideas and important points from the discussion on the board.
- Explain that today we will explore an important concept related to multiplication called factors.
