Bellringer 19 Sep What is 3/8 as a decimal? What is 0.75 as a fraction? The square root of 37 is between what two integers?

Bellringer 20 Sep True or false All integers are whole numbers All real numbers are rational A square root of 9 is -3 12 is a perfect square 3π < √81 “Calculating” square roots of non-perfect squares is annoying

Bellringer 21 Sep None

Bellringer 22 Sep 19 is between what two perfect squares? What are the principle square roots of those perfect squares? What is the difference of 19 and the perfect square before it? What is the difference of the two perfect squares from q 1? What is the answer from q 3 divided by the answer from q 4? What is a good first estimate for the square root of 19?
