I used this activity as alternative assessment for ISS 4.2.10; 4.5.10
Common Core Standards: 5.NBT.B.7 and 6.NS.B.3 adding/subtracting decimals; making change, but this could easily be an activity. Students worked in pairs taking orders and making change. The menu provides varied amounts so students need to add/subtract tenths and hundredths, as well as regroup. I used the "Race" cash but that is completely optional.
