NOTE ABOUT REALISTIC TEACHING MONEY

Lifelike 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 lifelike 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.

  • Money rules: http://www.moneyfactory.gov/resources/lawsandregulations.html

  • US Bills in general circulation today: $1, $2, $5, $10, $20, $50, $100.

  • Denominations last printed in 1945: $500; $1,000; $5,000; $10,000; $100,000.

  • Circulation of these larger denominations was discontinued in 1969, for lack of use.

  • The US Treasury never issued bills larger than $100,000.
