What your child is learning: to count collections of Canadian coins up to 200¢ (F1.1), building on the Grade 1 work of naming coins and their values. The key ideas are sorting coins, starting with the coin of greatest value, skip counting (by 5s, 10s and 25s) and counting on, and knowing that 100¢ = $1 and 200¢ = $2.
Common mistakes:
- Counting each coin as "one". Some children count 3 coins as 3¢. Ask, "What is each coin worth?"
- Switching skip-count patterns too early or too late. Have your child sort the coins into rows first and touch each coin while counting.
- Getting stuck counting by 25s. Practise "25, 50, 75, 100" like a chant. Linking it to quarter hours (later) or to 4 quarters = 1 loonie helps.
- Counting on from a dime after a quarter (25, 30 instead of 25, 35). Remind them to count on by the value of the coin they are touching.
About the penny: Canada stopped making pennies in 2012. When you pay with cash, the total is rounded to the nearest 5¢, so all amounts in this unit are counted in 5s. Grade 2 uses whole-cent amounts like 135¢; decimal notation ($1.35) comes in later grades.
How to help: Let your child count your loose change, or the coins in a piggy bank, in small handfuls (up to $2). Ask them to explain which coins they counted first and why. Supervise young siblings, since coins are a choking hazard.
