Learn multiplication tables in a structured manner (grade 3 math) - very effective!
By Math Mammoth
This method (I call it a structured drill) allows children to learn the multiplication tables in grade 3 or 4 faster and much more effectively than random drilling!
My book Math Mammoth Multiplication 1 at http://www.mathmammoth.com/multiplica... uses this method also. The book covers both the concept of multiplication and the practice of all the tables. It is available both as an instant download and as printed copy.
See a free example lesson from the book:

In the video, I use the table of 3 as an example and go through this three-step method.
In the first step, children memorize the skip-counting list. For the table of 3 this is: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36. They also practice saying it backwards, from 36 to 3.
In the second step, we work with the table itself, but it is written in order so the child can see its structure. The " randomness " comes from me (the teacher) pointing to various problems in a random order. I also like to point out certain benchmark facts to students: 10 x 3 is 30 and 5 x 3 = 15 are such facts because they're in the 10s table and in the 5s table, which the children probably have learned first.
We also practice the tables " backwards " where the " answers " are written and the student tells how many times 3 they are. For example, I point to ___ x 3 = 24, and the child is supposed to say " 8 " . This type of practice makes children learn basic division facts at the same time without realizing it! This really helps third grade students because division is also a topic for third grade math.
Partial Fraction Decomposion
By The Organic Chemistry Tutor
This precalculus video tutorial provides a basic introduction into partial fraction decomposition. The full version of this video contains plenty of examples and practice problems with repeated linear factors and repeated quadratic factors. Partial fraction decomposition is the process of taking a complex fraction and breaking it into multiple simpler fractions. It's the reverse of adding combining two fractions into a single fraction.
Integration By Partial Fractions
By The Organic Chemistry Tutor
This calculus video tutorial provides a basic introduction into integrating rational functions using the partial fraction decomposition method. Partial fraction decomposition is the process of breaking a single complex fraction into multiple simpler fractions. The integrals of many rational functions lead to a natural log function with absolute value expressions. This video explains what to do when you have repeated linear factors and quadratic factors. This tutorial contains many examples and practice problems on integration by partial fractions.

Properties of matrix multiplication
By Khan Academy
Sal shows that matrix multiplication is associative. Mathematically, this means that for any three matrices A, B, and C, (A*B)*C=A*(B*C).
Properties of matrix multiplication
By Khan Academy
Sal determines which of a few optional matrix expressions is equivalent to the matrix expression A*B*C. This is done using what we know about the properties of matrix addition and multiplication.
Geometric transformations with matrix multiplication
By Khan Academy
Sal finds the drawing that appropriately represents the effect of a given 2x2 transformation matrix on the plane.
Scalar matrix multiplication
By Khan Academy
Sal defines what it means to multiply a matrix by a scalar (in the world of matrices, a scalar is simply a regular number).
