This video tutorial teaches how to determine if a number is even or odd by dividing objects into two equal groups. It uses examples with unifix cubes, buttons, bowls, and balls to illustrate the concept. The video explains that an even number can be divided equally with no remainder, while an odd number leaves one object unpaired. Through practical examples, viewers learn to identify even and odd numbers by checking for leftover objects after grouping.
