Today many of us were able to estimate the square root of irrational numbers. For those still experiencing difficulty just remember that your perfect squares tell you what numbers your estimated square root should be between. For example if we needed to find out the square root of 28, we know that 28 is between the perfect squares 25 and 36. Since the square roots of these numbers are 5 and 6 respectively, then the square root of 28 is going to be a number between 5 and 6. We can then guess and check our answer by multiplying that value by itself. The following video contains an example. You may also click here for more information on estimating irrational numbers.
The homework tonight is to read pages 148-9 and complete problems 9-25 (odd), 27-31, 33-42. Also, this week you have a study island assignment. The assignment is titled: "Rational and Irrational numbers 3." I will give you until next Friday to complete this study island assignment. Please remember that you may redo it for a higher grade. Do not guess because it will make your grade lower. Also you have a test this Friday.
