It all starts here with addition! Learning addition is the first step on your way to subtraction, and makes up the foundation of all of the strategies used to teach multiplication. These math fact timed tests and multiple digit addition problems should make up the core of your strategies for teaching addition concepts, but when you are ready for alternative strategies:
- Picture Math Addition.
- Addition Flash Cards.
- Addition and Subtraction Grid Puzzle Worksheets.
That still leaves the problem of memorizing a string of numbers, and here’s where the magic is. Teach children to skip count to the tune of a simple song. Have you ever wondered why children can learn the lyrics to songs so easily? It is because music can be used as a Mnemonic device, that is a strategy to assist with memorization. If you can associate the numbers with the sounds in a song, the children will not only learn them faster, but retain them much longer than they would memorizing them exclusively through repetition.
We often talk of dividing as being the reverse of multiplying, and indeed when dividing fractions this is the case. The way you divide fractions is very similar to the way fractions are multiplied with a simple twist in the middle.
Start by following the basic process for fraction multiplication, turning any mixed fractions into improper ones. Before you cross cancel or multiply, however, swap the numerator and the denominator in the second fraction. This is called taking the reciprocal and it is the key step to turn this into a division operation. Then, cross cancel, multiply across to get the answer fraction, and reduce.
