Let's begin our journey together in 5th grade with good ole fashioned arithmetic. Don't assume that this has to be boring...not at all! We're going to have fun as we learn about and practice adding, subtracting, multiplying, and dividing whole numbers and decimals. We know you're probably pretty comfortable with basic arithmetic, so we'll try to challenge you a little more in these tutorials!
Common fractions and decimals
Learn about common fractions and their decimal forms like 1 /2 = 0.5, 3/4 = 0.75, and 2/5 = 0.4.
You get the general idea of decimals and what the digits in different places represent (place value). Now you're ready to do something with the decimals. Adding and subtracting is a good place to start. This will allow you to add your family's expenses to figure out if your little brother is laundering money (perhaps literally). Have fun!

The real world is seldom about whole numbers. If you precisely measure anything, you're likely to get a decimal. If you don't know how to multiply these decimals, then you won't be able to do all the powerful things that multiplication can do in the real world (figure out your commission as a robot possum salesperson, determining how much shag carpet you need for your secret lair, etc.).
In this tutorial, we'll extend our division skills to include decimals! We get into some pretty fun stuff here including dividing decimals by whole numbers, and dividing whole numbers by decimals. Finally...dividing decimals by decimals. Common Core Standard 5.NBT.B.7
