Percentages With Base Ten Blocks


Get some practice with base ten blocks and Percentages are SUPER EASY:

Base ten blocks make percentages SUPER EASY to understand. After you watch the videos on the next page some of the problems you may have had with figuring out questions like "27 is what percent of 90?" Or "18 is 30% of what number?" may disappear forever. And you will see why just having that red block made it fast and easy for Dboyz to SEE what they were doing instead of memorizing rules about when to multiply or divide.

Looks like magic but it's not, it's just math made easy, simple and fun: Child's Play.


Here is a short vid telling you what's in store for you after you hit


ENTER.



Get yourself a password and you too could be teaching your eight year old (or even your 5 year old, hard to believe I know) to do percentages in their heads. Problems like 18 is 60% of what Number? Are now "no problem..."

The days of the $24.00 annual password are long gone.  But $49.95 is a heck of deal, some people would say a STEAL, when you consider all the pages you get with the "sitewide" password. The trig page alone is worth $49.95. EASILY. Percentages concepts are easy and fun to master and as you can see it won't take you long to do it once you have the right tools and this method.
