MA.7.NSO.1 is a B.E.S.T. standard. These are the benchmarks under it.

Teacher's field guide

What Students Need to Do: Students rewrite rational numbers as fractions, terminating decimals, or repeating decimals. They also apply exponent rules to evaluate expressions and write equivalent forms.
What Mastery Looks Like: Students move accurately among fractions, terminating decimals, and repeating decimals. They also use exponent rules to evaluate expressions and produce an equivalent expression, including when the base is negative or fractional.
Common Misconceptions: Students may think a repeating decimal stops, or write only a few repeated digits without a bar or ellipsis. They may multiply exponents when multiplying like bases instead of adding them. Negative signs and fractional bases also cause errors when powers are evaluated.
How to Assess It: Give an exit ticket: Write 0.272727… as a fraction, then simplify (2/3)² × (2/3)³. Ask students to show each step.

Lesson moves

Use fraction strips, decimal grids, and calculators to match fractions with terminating or repeating decimal forms.
Ask students to explain why 0.333… equals 1/3 and defend their reasoning with multiplication or a diagram.
Play a card-matching game with equivalent fractions, decimals, repeating decimals, and exponent expressions.
Compare store discounts written as fractions, decimals, and percents, then decide which form makes each comparison easiest.
