1. Estimating Square Roots to the Tenths and Hundredths Place

2. Review Yesterday we discussed estimating square roots between two integers and discussed how to improve our estimate to the tenths place.

3. Estimate the square root of 3

4. At this point, we have to make an educated guess and calculate the squares of rational numbers which include decimals – You should notice that the square root of 3 is most likely larger than 1.5

5. 1.5² = 1.5 x 1.5 = 2.25 1.6² = 1.6 x 1.6 = 2.56 1.7² = 1.7 x 1.7 = 2.89 1.8² = 1.8 x 1.8 = 3.24

9. Think Pair Share

10. Discussion How could we improve the estimate to the hundredths place?

11. 0 4 21 3 3.13.23.3 3.43.53.63.7 3.8 3

12. Now We Move to the Hundredths Place and Continue the Process
