Negative numbers (I. Whole Numbers, Number line)

Hello boys and girls,

now that the weather is getting colder, it is the best time of the year to study NEGATIVE NUMBERS :-)

These are part of a bigger group, called Whole Numbers.

To study them, the number line is very useful; it may help you to tell which numbers are bigger or smaller. Read about number line by clicking here (remember to solve the six questions down). After that, play this game for a while to see if you really understood...

At the end of the class, if you feel comfortable with number line and operations on it, try with this game, with more difficult movements... Play

Good luck,
