L5 · Money: cents as dollars in decimal notation
Learning goal
“I can change cents into dollars and dollars into cents using decimal notation, and write money amounts correctly with a dollar sign and two decimal places.”
Cent — the smallest Canadian coin unit. 100 cents make one dollar.
Dollar ($) — the whole unit of Canadian money. Amounts are written like $3.45.
Decimal notation — writing an amount with a decimal point: the part before the point is whole dollars, the two places after it are cents.
Worked example
Change 345 cents into dollars. Every 100 cents is 1 dollar. 345 cents = 3 full dollars (300 cents) and 45 cents left over. In decimal notation: $3.45. The two places after the point are ALWAYS the cents: tens of cents, then cents. Say it: "three dollars and forty-five cents" - the and marks the point, just like in L1.
Check yourself — explain it
In $3.45, the 45 after the point means 45 cents because...
