Exploring Fact Families in Mathematics

This video tutorial introduces the concept of fact families using multiplication and division. It explains the inverse relationship between these operations and highlights the commutative property. The content aligns with standards for multiplying and dividing within 100, emphasizing fluency and memory of one-digit products by the end of third grade. Through examples and activities, students learn to identify fact families and understand their structure.
