Grade 6th on Khan Academy: By the 6th grade, you’re becoming a sophisticated mathemagician. You’ll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data!

Unit Conversion: Centimeters To Meters | Measurement And Data | 5th Grade | Khan Academy

Which are smaller: centimeters or meters? If you know the answer to that question, then solving this problem gets a little easier. Let’s convert centimeters to meters. Practice this lesson yourself on KhanAcademy.org right now: Watch the next lesson: Missed the previous lesson? 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)!
