Resources

Benchmark

Indicator

 

A.   Use scientific notation to express large numbers and numbers less than one.

1.   Use scientific notation to express large numbers and small numbers between 0 and 1.

  

B.   Identify subsets of the real number system.

1.   Recognize that natural numbers, whole numbers, integers, rational numbers and irrational numbers are subsets of the real number system.

2.   Apply order of operations to simplify expressions and

perform computations involving integer exponents and

radicals.

 

C.   Apply properties of operations and the real number system, and justify when they hold for a set of numbers.

1.   Explain and use the inverse and identify properties and use inverse relationships (addition/subtraction, multiplication/division, squaring/square roots) in

problem solving situations.

  

G.  Estimate, compute and solve problems involving real numbers, including ratio, proportion and percent and explain situations.

1.   Determine when an estimate is sufficient and when an exact answer is needed in problem situations, and evaluate estimates in relation to actual answers (e.g., very close, less than, greater than).

2.   Estimate, compute and solve problems involving rational             numbers, including ratio, proportion and percent, and judge the reasonableness of solutions.

 

H.   Find the square root of perfect squares, and approximate the square root of non-perfect squares.

1.   Find the square root of perfect squares, and approximate the square root of non-perfect squares as consecutive integers between which the root lies (e.g., 1 3 0 is between 11 and 12).

 

I.    Estimate, compute and solve problems involving scientific notation, square roots and numbers with integer exponents.

1.   Add, subtract, multiply, divide and compare numbers written in scientific notation.
