Math Journey
This site offers a fun way to test math skills in addition, subtraction, multiplication, division and rounding. You can travel around the world by answering 30 math equations. You start the game in London by boarding a plane, and have 30 stops along the way. Each time you stop, you must answer a math problem correctly before you can board the plane to your next destination on your journey around the world. If you answer a question incorrectly, you miss your flight. If you miss three flights, you must start over.
The game allows you to customize it to test the skills you want to practice. So you can choose all addition problems with one digit numbers, for example, or you can select 4-digit multipliers, or a combination of all the basic math strands at varying levels of difficulty.
When you get to the site simply read the instructions, select the skills you want to practice, and begin the game.
