Mastering Multiplication with Multiples of 10

The video tutorial explains how to multiply by multiples of ten using a model of cubes. It demonstrates the concept with examples, such as calculating the total number of cookies in boxes and water bottles in cases. The tutorial highlights a pattern in place value changes when multiplying by ten, making it easier to understand and apply multiplication in practical scenarios.
