Rational and Irrational Numbers

Irrational numbers aren’t crazy — they just look it! In this BrainPOP movie, Tim and Moby introduce you to the difference between rational and irrational numbers. You’ll start out by learning how mathematicians divide up numbers, what a whole number is, and when fractions can be whole numbers. You’ll also learn what integers are and what they have to do with rational numbers. Discover how a decimal can be a rational number, and what it means when a decimal terminates or repeats. Finally, you’ll see what irrational numbers are and learn about some examples. And if all else fails, remember that fractions put the “ratio” in “rational”!
