L3 · Counting money: coins and bills of the same kind
Learning goal
“I can find the value of a group of coins or bills that are all the same kind, by skip counting.”
Dime — a coin worth 10 cents, written 10¢. Dimes are counted by 10s.
Quarter — a coin worth 25 cents, written 25¢. Quarters are counted by 25s.
Loonie — a coin worth 1 dollar, written $1. A toonie is worth $2.
Value — how much a group of coins or bills is worth altogether.
Worked example
Find the value of 4 dimes. Step 1 (name the coin's value): one dime is worth 10¢, so we count by 10s. Step 2 (touch and count): one count per coin - 10, 20, 30, 40. Step 3 (state the value): 4 dimes are worth 40¢. Say it plainly: the coin tells the step. Dimes say "count by 10s"; quarters say "count by 25s."
Check yourself — explain it
To find the value of 3 quarters, I count by 25s because...
Paired problem — example still visible
Find the value of 5 dimes -> 50¢ (count by 10s: 10, 20, 30, 40, 50)
Faded completion — last step is yours
"3 quarters counted by 25s: 25, 50, ___ - the value is ___" -> 75¢
