The Common Core State Standards require a balance of three fundamental
components that result in rigorous mathematics acquisition: deep conceptual
understanding, procedural skill, and mathematical applications and modeling.

Dinner was $ 1 9 .8 5 . We wanted to leave a tip that
was 2 0 % of the cost of the meal. 1 9 .8 5 is almost
20 and 2 0 % is equivalent to

is about 2; 2.280 can be rounded to 2
and 0.95 can be rounded to 1 in order to estimate a
quotient of 2 because 2  1  2 .

Students may estimate. Since 3 0  5  6 the decimal
point should be placed as 5.45.
3 2 6 .8 7 2  3 6 .4  8 .9 8

Students may look at this problem as 8 .9 8  3 6 .4  ? .
Since 9  3 6  3 2 4 the decimal point should be placed
between the 6 and 8; 3 2 6 .8 7 2  3 6 .4  8 .9 8 .
Multiply and divide multi-digit decimals using the standard
