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. 
 (a) In general, photocopies of currency must be sized < 75% or > 1.5 times the original. 
 (b) Must be one-sided.

US Bills in general circulation today: $1, $2, $5, $10, $20, $50, $100. 
 (a) Denominations last printed in 1945: $500; $1,000; $5,000; $10,000; $100,000. 
 (b) Circulation of these larger denominations was discontinued in 1969, for lack of use. 
 (c) The US Treasury never issued bills larger than $100,000.
