Scientific notation is can be very confusing to students. They confuse the positive and negative exponents and when to use them. I have found that by teaching the students to find the old decimal point, label where the new one should go, and count from new to old, it forces them to move in the positive or negative direction, making the sign of the exponent much easier for them to figure out!

Before I move on to percents, order of operations, or even ordering numbers, I like to revisit equivalent rational numbers. I want to make sure that they are comfortable changing numbers into different, equivalent forms.

This is a tic tac toe type chart that can be used to help recall the integer facts for multiplcation. No matter how it is read, it is always correct! + x + = + + x - = - - x + = - - x - = +

Estimation is an important skill that needs to be reviewed no matter the age.

Each student is given a credit card with a limit- I chose $500. They are "charged" for different things- such as missing homework, leaving the room etc. They are also given a savings account- I chose to give them $700. They can also earn money for positive actions such as: helping others etc. Charges and earning can be changed and modified depending on your class. Then once they get used to it, I introduce purchases that can be made. The students really enjoy it.

Taking numbers in different forms and order them from least to greatest.

This is a simple chart to help remember the rules when multiplying integers!
