Money Matters

  • Units of Work
  • Number and Algebra
  • Level Three

In this unit, students will explore Number concepts through the real world Measurement context of Money.  A variety of money contexts will be explored using paper play money, at first trading only $1, $10, and $100 notes, and eventually extending the trades and operations into using thousands, millions and billions of dollars. 

Students will be involved in making fair trades and exchanges of their money in order to have practical experiences with the essential "rules" of our place value system. Namely, that any ten of one denomination is equal to one of the next higher order (ie. 10 ones = 1 ten, 10 tens = 1 hundred, 10 hundreds = 1 thousand and so on).  The money context, with real world problems, will be used to enable students to make sense of, and to "unlock", the keys to the language, patterns and rules of our place value system.  By exploring large numbers through the concrete material of play money, students will gain confidence decoding and reading multi-digit numbers involving, ones, tens, hundreds and eventually, thousands, millions, billions, trillions etc.
