5th grade (U.S.)

Whether you are a robot, possum, magic unicorn, or just a normal human being, 5th grade is incredible! You will deepen your knowledge of the decimals that you were first exposed to in 4th grade. In particular, you'll learn to do all the arithmetic operations--addition, subtraction, multiplication, division--with them and really understand what a decimal represents. This will be complemented by building your fraction muscles where you'll learn to add, subtract, and multiply any fractions (and begin to divide them). On the measurement front, you'll explore volume (or how much "space" something takes up) and continue the unit conversion journey begun in 4th grade. 5th grade is also the first time that you get exposed to the fundamental concept of graphing points on a coordinate plane, and you'll get a very brief exposure to the concept of exponents (when exploring "powers" of 10)!

Arithmetic operations

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!

Fractions

Hey...we know that fractions may not be your favorite thing. But these little guys already feel inferior to their whole number big brothers, so cut them some slack. Besides that, using fractions isn't too hard once you get the idea and start practicing. So let's go! In this group of tutorials you'll be adding, subtracting, multiplying, and dividing fractions, whole numbers, and mixed numbers.

Place value and decimals

Here begins our journey towards a thorough understanding of place value and decimals! Too often, students allow themselves to be intimated by decimals and fail to see that they are simply expressing a difference in the powers of ten. No worries! Just follow along with us. These tutorials and videos will lay the groundwork for later understanding of more complicated concepts. In addition to decimals, place value, and powers of 10, we'll look at regrouping, comparing and rounding decimals too.

Measurement and data

If you think about it, we measure almost everything: time, distance, size, weight, volume, etc. Every THING can be measured. The question is, what unit of measurement is used and how is that unit constructed, compared, and converted? This last part is what we explore in these tutorials.

Geometry

We're going to stick our toes into the proverbial waters of geometry! For those of you that are visual learners you'll love this topic. We'll examine all kinds of lines and shapes in the 1st, 2nd, and 3rd dimensions. Topics we'll cover include the coordinate plane, plotting points, quadrilaterals, parallelograms, trapezoids, and rhombi (plural for a rhombus). Start your engines!

Algebraic thinking

Arithmetic is fun, but algebra is a blast! Look, nothing is easy the first time you try it so don't get discouraged. These tutorials will give you some straightforward explanations and examples to get you started down the road of algebraic thinking. We'll practice writing and evaluating numerical expressions, as well as seeing, interpreting, and graphing patterns and relationships between numbers. We're laying the foundation for lots of good learning ahead!

Adding decimals

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! Common Core Standard: 5.NBT.B.7

Subtracting decimals

Anything you can do with whole numbers, you can do with decimals. Subtraction is no exception. In this tutorial, you'll get some good practice subtracting decimals up the hundredths place.

Multiplying whole numbers and decimals

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.). Common Core Standards: 5.NBT.B.5, 5.NBT.B.7

Dividing by two digits

We're taking division a step further and moving beyond single-number division. Let's learn to divide any whole number by a multiple-digit whole number! Common Core Standard: 5.NBT.B.6

Dividing decimals

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
