Multiplication_by_10s_100s_and_1000s
Learn to multiply whole numbers by multiples of ten. Example: 7 x 500 = 3500
Learn to multiply multi-digit whole numbers with and without regrouping.
As we'll see in this tutorial, multiplying a multiple of 10--like 10, 20, 30, 40, etc.--by a single digit number is not too much more complicated. Common Core Standard: 3.NBT.A.3
Some division problems don't work out perfectly. For example, we know that 6 divided by 3 is 2, and 9 divided by 3 is 3. But, what is 7 divided by 3? Or 8 divided by 3? In division problems like these, we're left with remainders.
Learn about the commutative, associative, and distributive properties of multiplication. Solve multiplication problems by changing the order of factors (commutativity), the grouping of factors (associativity), and by decomposing the factors (distributive property).
Dividing big numbers can be difficult to wrap your mind around. In this tutorial, we'll learn some visual ways to think through large division problems.
