Division of Decimals by 2-Digit Divisors
The process of division remains the same no matter how many digits you are dividing by. Today we divided by two- digit divisors into a decimal number. Like yesterday, the process is still the same, it's just the idea of a decimal point that throws my kids off. It is just a matter of placing the decimal in the quotient before beginning to divide.
Of course the next problem was dividing by a two digit divisor. It's not the process, it is the fact that you have to work to determine the "number of times" a two-digit divisor "goes into" the dividend. Not a favorite of my 5th graders.... working....
The page I had them work on was called "Behind the Scenes." I found it it The Mailbox: Teacher's Helper, the June/July 2012 issue, p. 33. The page had the kids solve 6 multiplication and 6 division problems. The assignment was made a little more challenging by the fact that you had to use a code to determine the numbers to use. We did have 30 minutes of classtime to work on the assignment.
