Try your hand at drawing fractions that are equivalent to each other (actually 2 others). This is really great to do to practice so that you can visualize what different fractions 'look like'.

Sal's Sub Shop
Need practice with reading a ruler? Try your hand at making sub sandwiches at Sal's Sub Shop.
Directions for game - copied directly from site:
Be careful, Sal! You have some very picky customers who really know what they want! Luckily, your the person for the job. You have three minutes to fulfill ten customer orders. Because you cater to a cosmopolitan bunch, some patrons might order their subs in metric units of length, while others might order their subs in standard units of length. Don't worry Sal, you have precision rulers that can take care of both kinds of orders. The question is...can you use those rulers when a customer orders a sub 5 and 10/16 inches long, or 12 and 2/5 centimeters long? If your precision can satisfy all ten customers, you can print out your "Super Sub Maker" certificate to show off to the world.

The Pumped Up World of PreAlgebra
This is a fun video about PreAlgebra.
From their site:
'The Standard Deviants team uses their colorful approach to make math entertaining. Features topics including integers, multiplication, division, rounding, fractions, and ratios.'
It's free. Just download and watch it on your computer. I haven't watched the whole thing yet, just the very beginning, but it looks promising...
If you like it, they also made a video for Basic Math. Integers are included in this Basic Math video, so if you need to review Adding, Subtracting, Multiplying or Dividing Integers, it's there!

Here is another online game for Scientific Notation. I guess there isn't too much exciting about it either...but it beats having to do pages of worksheets!

Why do we need/use Scientific Notation?
Here is a great article about why we use Scientific Notation. The article is from the Institute for Energy and Environmental Research (IEER)
There is an accompanying Worksheet too! Answers are at the bottom of the page.

Coffee Shop Game
Here is a game where you set up a coffee shop for 14 days and your job is to earn as much money as possible in the 14 days. You purchase ingredients, set your price and make the coffee recipe. This is a fun way to practice using decimals!
To earn the max amount, be sure to grab paper and pencil and do a few calculations before choosing prices, etc.
