Grade 5th on Khan Academy: 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)! (Content was selected for this grade level based on a typical curriculum in the United States.)

  1. Yes there is a mistake and we all caught it, but considering these are extremely high value FREE lessons I think ya’ll need to show respect to the MAN!

  2. Oh my god you messed up for all u people the answer is 72 #you messed up FIX IT OR I WILL DIE OF RETARD NESSES FIX IT

  3. I think you guys are being a little harsh. It is a mistake they should fix, but the actual math that Sal does in the second half is correct, which is the important part.

  4. Sal, there’s a mistake at 0:46. It would be great if you just put a note warning the mistake and the correct way for solve the problem. Thanks.

  5. “Decimal divisors in the hundredths place can be a little confusing” as said in description. Especially when you made the 24 and 42 mistake.

  6. Seriously how do you go from 30.24 to 30.42 that should change equation? How does that make sense?

  7. He made a mistake :46. I would make fun of him if it was not for the fact that this is the most common mistake that I make during these Khan courses.
