 Number System: Videos

Here are some videos to help with understanding the number system specific to 6th grade.  The Khan Academy has plenty of videos on the subject of numbers for all grades and is an excellent resource for almost every math lesson.  Math Antics is another excellent resource when it comes to understanding our math concepts and is actually quite entertaining.  If and when you get lost, check out these two resources for a little more help.  To the right are links to both websites for specific lessons and videos:

Number Strings:
​Adding and Subtracting Fractions

THE MONEY MODEL
The "Money Model" that is used to add and subtract fractions is a great choice if you have to compute halves, quarters, fifths, and tenths.  The common denominator is always 100, so the student is constantly finding equivalent fractions.  For instance 3/5 + 1/4 is equal to 60/100 + 25/100 = 85/100 or 17/20.
THE CLOCK MODEL
The "Clock Model" is another great option, except with this model we can compute more fractions with unlike denominators.  With the "Clock Model" students can add and subtract halves, quarters, fifths, and tenths, but also thirds, sixths, and twelfths.  The common denominator is always 60. Here is a sample problem:  2 1/3 - 5/6 is equal to 140/60 - 50/60 = 90/60 or 1 1/2.
