Place value notes

Introduction to place value

r

This video is an introduction to place value (tens and hundreds). Place is the place of a digit within a number. Value is how much a digit is worth.A digit is a single numerical symbol, a number is one or more digits together.

Division / divisibility

Divisibility rules, prime, and composite

r

A prime number is a number that is only divisible by itself and 1. A composite number has more than 2 factors. Factoring is to express a whole number as a product of other whole names, for example: we can factor 12 as 3x4 or 2x6 - both are whole numbers that multiply to make another whole number.
