Subtracting Dimes

1.NBT.6
Module 12
Differentiation Activity

Each pair of students will have 9 dimes.  They can either use the play money or the printables below.  One student will put more than 1 dime on the table.  Together the students count the amount of money.  For example, in the problem to the left, there were 8 dimes for 80 cents.  One student covers up some dimes when the other turns around.  They may use paper, fabric, etc.  The student them must figure out how many dimes are missing.  In this instance, there are two missing.  The matching subtraction sentence is then recorded.  80-60=20.
