A fun, interactive introduction to quantitative reasoning skills for the ISEE Lower Level exam.

Basic Concepts

Comparing Quantities and Estimation

Comparing Numbers and Estimating Answers

Sometimes, you need to know which number is bigger, smaller, or about the same. That's comparing quantities! Estimation is about making smart guesses—super useful when you need an answer quickly.

Comparing Quantities

Use symbols like \( > \) (greater than), \( < \) (less than), and \( = \) (equal to) to compare numbers. For example, 8 > 5.

Estimation

Estimating helps when you don't need the exact answer. If you're buying snacks for a group, you might estimate how much you'll spend so you bring enough money.

Real-World Use

From shopping to playing games, comparing and estimating helps you make quick decisions and check if your answers make sense.

Examples

  • Is 27 greater than or less than 35?

  • If each toy costs about $3 and you want 4 toys, how much do you need in total?
