Students will
add
and
subtract decimals
to the hundredths (5.NBT.7).
Adding and Subtracting Decimals
Adding decimals: 9.087+15.31 (video) | Khan Academy
Sal solves 9.087+15.31 using the "standard algorithm".
Subtracting decimals: 9.57-8.09 (video) | Khan Academy
Sal subtracts 9.57-8.09 using "standard algorithm".
Students will
multiply
and
divide decimals
to the hundredths place using various strategies (5.NBT.B7).
Multiplying decimals example (video) | Khan Academy
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product. For example, if we multiply 7.61✕9.2, we will have 3 digits behind the decimal in our product because there are 3 digits behind the decimals in the factors.
