Understanding Multiples and Factors

This video tutorial for fourth grade module 3, lesson 24, focuses on understanding factors and multiples. It emphasizes the importance of vocabulary in math, suggesting the use of a word wall for better retention. The lesson provides strategies for teaching factors and multiples side by side, using examples with numbers like 4 and 10. It highlights the infinite nature of multiples compared to the finite nature of factors. Practical exercises are included to reinforce the concepts, and the lesson concludes with a recap of key vocabulary terms.
