In yesterday's post we looked at representing addition and subtraction problems with equations. We also started looking at the relationship between multiplication and division facts. We're continuing with that theme today by looking at how to represent multiplication and division problems with equations. We'll also take a quick look at the beginnings of long division.
Representing Multiplication and Division
Learning how to display problem situations that involve multiplication and division can be a tricky business. Here's a video to show you how it's done.
Now you can try it out yourself. Take a look at these sample problems from a released STAAR test below.
Here's another problem that you can use to test your skills.
Intro to Long Division
While students don't need to become fully proficient at the standard algorithm for dividing larger numbers, usually called long division, until 4th grade, they might need it on occasion while in 3rd grade. Here's a quick recap of that skill in action.
While you don't need to use long division to solve the problem below, it's always good to know how it's done.
