Overview of numeration and math language by Dr. Steve Chrisomalis, a linguistic anthropologist at Wayne State University-Detroit:
NOTE ABOUT REALISTIC TEACHING MONEY
Life-like bills are highly recommend because learning disabled students have great difficulty generalizing or applying practice to real-life situations. Learning the basic concepts using real coins and life-like bills, will assure that understanding is transferred to real problem solving.
Play money and plastic coins and counters are of limited value to dyscalculic students. Obviously, the life-like bills used here are solely intended to illustrate place value in the base-10 system.
There are federal rules concerning reproductions of actual US currency.
- In general, photocopies of currency must be sized < 75% or > 1.5 times the original.
- Must be one-sided.
