This lesson showcases the multiplication table.
Watch and learn how we can use a number line to understand factors and multiples visually!
Factors and multiples are opposites. How? A factor is number that can be multiplied by another number to get a new number. A multiple (of the factor) is that new number!
Multiplication Properties are expanded as we learn to multiply 1-digit by 2-digit numbers.

Multiplication by two- and three-digit numbers.
In this video, we will learn how we can use our understanding of the multiplication table to multiply longer numbers for larger products. By the end of the video, students should be able to multiply any 2- and 3- digit numbers, and begin to observe patterns for dealing with several-digit numbers.
Multiply several digit numbers quickly by estimating products confidently and consistently.
We will learn the art of rounding, and how it can help us estimate products. Additionally, we will learn the principles of place-values (specifically "1s", "10s" and "100s" place values), and how to account for them when estimating products.

In this lesson, we will continue our study of statistics, particularly to explore the idea of a median and mode. We will compare these statistical measures to the previously-studied mean (average), as well as with one another. We will brainstorm useful ways to distinguish these, and practice strategies for identifying them with sample data sets.
