Warm Up Answers Rational Irrational

Estimating Irrational Numbers

Remember your perfect squares.

It is closer to the 7.

Practice Estimate. Find the two consecutive integers the number falls between and circle the one it is closest to. 45 28 160 12 91

Closure Estimate 55 to the nearest tenth. Hint: Start off estimating as we have been in class and then place the number on a number line.
