Crystal Ball (Part 1) (Comparing the value of the product to one of its factors based on the other factor)

This lesson explores how to predict the product of numbers based on their factors. It begins with simple examples, such as multiplying 10 by 0, 1, and 2, to demonstrate how the product changes. The lesson highlights that multiplying by a number less than one results in a product less than 10, while multiplying by a number greater than one results in a product greater than 10. The concept is further explored using fractions, specifically 1/2, to show how the product is less than 10. The lesson concludes by generalizing these relationships to all positive numbers.
