H.1A.3: Express square roots in equivalent radical from and their decimal approximations when appropriate.
Learning Targets:
 Use order of operations to solve expressions including exponents and square roots.
 Express square roots with decimal approximations.
Warm-up: H.1A.3 Warm up
Teach:
 Review order of operations; include methods of showing work like pizza slice
(pyramid) way and to remember that M and D, A and S are the same step:
7 + 8  3 – 6 P
7 + 24 – 6
31 – 6

Mom and Dad
Adam and Sally (kids!)
 Expanded form and exponential form
 Inverse: squaring and square root.

 Approximate square root with decimals and between whole numbers.
Active Engagement:
 Student should be taking notes for examples: drawing pictures, pyramid way, family matters, hop scotch.
 Create a problem and it give it to a neighbor to solve
 Word problems
 Calculators make mistakes…not all calculators are created equal
 Find the mistake with problems worked incorrectly
 Fill in the symbol for order of operations problems to make the solutions true.

Common Misconception:
 Putting multiplication first then division (or addition and subtraction) rather than treating them as one step that should be done at one time from left to right
