Estimate products and quotients for word problems involving multi-digit decimals.
Fluently multiply and divide multi-digit decimals using the standard algorithm.
Instructional videos in the hyperlinks above are meant to support C2.0 content,
but may use vocabulary or strategies not emphasized by MCPS.
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.


Estimate products for multiplication problems involving
multi-digit decimals.

Estimate quotients for division problems involving multidigit decimals.
o
If 12  2  6 , then 1.2  2  0.6 and
0.12  0.2  0.006 .
o
2.280  0.95 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 .

Estimate how much tax would be paid on different items in a sale
advertisement given a $0.06 tax rate.
Determine how much money would be spent when buying
different quantities.
Determine what each person’s share of a restaurant bill would be
and calculate tip as 0.15 or 0.2.
Determine where the missing decimal point should go in a number
sentence:

31.61  5.8  545
 Students may estimate. Since 30  5  6 the decimal
point should be placed as 5.45.
326872  36.4  8.98
 Students may look at this problem as 8.98  36.4  ? .
Since 9  36  324 the decimal point should be placed
between the 6 and 8; 326.872  36.4  8.98 .
Multiply and divide multi-digit decimals using the standard
algorithms.
