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!

This powerpoint is a lesson dealing with finding perfect squares and perfect cubes, define what square and cube mean, and begin discussing how to simplify square roots.

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 - = +

Helping students to classify the difference between rational and irrational numbers.

This lesson can span over 2 days. I review rates, unit rates, ratios and proportions, then spend the next day dealing with percents. I teach the students not only to use proportions when solving percent problems, but also to use equations, because as percent problems become more complex, it is easier to use equations then it is to use proportions.

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

This can go hand in hand with equivalent rational numbers. Here, students practice dividing decimals by decimals, making change, etc.
