This task supports a couple of different standards in first grade, but I feel it best fits 1.OA.B.3 if used with the Act 2 problem “there are three groups of five and four more.”  It would fit standard 1.NBT.B.2 if using the Act 2 prompt “there is one group of ten and nine more.”

It would be a great place to start before introducing counting on with coins in second grade for standard 2.MD.C.8.

Act 1:

Act 2:

1.OA.B.3: There are three groups of five and four more

1.NBT.B.2: There is one group of ten and nine more

Act 3:
