Comparing and Evaluating Numbers

The video tutorial introduces students to comparing numbers using place value and base 10 blocks. It begins with a racetrack-themed introduction to comparing numbers by examining the tens and ones places. Teacher Mike then explains the value of base 10 blocks, using cubes and longs to represent numbers, and demonstrates how to compare them. The video includes a worksheet activity to reinforce these concepts. Finally, a Thanksgiving-themed activity helps students practice identifying numbers less than 57 using a number line. The video emphasizes starting with the largest place value and using comparison symbols correctly.
