Multiplication and division

Let's continue on the multiplication and division adventure that was started in third grade. We'll think about multiplying and dividing with whole numbers and discover that sometimes we have a leftover, or a remainder, when we divide. These tutorials will also help you get comfortable with multiplying multi-digit numbers, long division, and solving word problems. Let's do this people!

You know your multiplication tables (and basic division) from the 3rd grade and are ready to learn how to multiply and divide multi-digit numbers. Imagine the possibilities! This tutorial will make you unstoppable.

In this tutorial, we look at multiplication and division through the lens of comparison. For example, say that you are 9 and 3 times older than your cousin. How old would your cousin be? Multiplying a number times 3 gets you to your age, 9. Can you figure out the answer? We'll go through several exercises together so you get enough practice to feel confident multiplying. By the way, memorizing your multiplication tables helps a lot!

Dividing big numbers can be difficult to wrap your mind around. In this tutorial, we'll learn some visual ways to think through large division problems.

You know your multiplication tables and are getting the hang of basic division. In this tutorial, we will journey into the world of loooong division (sometimes, referred to as "long division", but that's not as much fun to say). After this tutorial, you'll be able to divide any whole number by a single digit number.

Some division problems don't work out perfectly. For example, we know that 6 divided by 3 is 2, and 9 divided by 3 is 3. But, what is 7 divided by 3? Or 8 divided by 3? In division problems like these, we're left with remainders.

In this tutorial, we'll start to challenge you with more sophisticated multiplication and division word problems. If you understand mult-digit multiplication and long division, you have all the tools you need to tackle these. May the force be with you! Common Core Standard: 4.OA.A.3
