Comparing Whole Numbers in Space

Astronaut Steve and his friend Lenny teach how to compare whole numbers using comparison symbols like greater than, less than, and equal to. They use an alligator analogy to explain that the symbol opens towards the larger number. Through examples like a star counting competition and comparing space shake costs, they demonstrate how to use place value to determine which number is greater or if they are equal.
