What your child is learning: to recognize all Canadian bills, including the new-to-them $100 bill (brown), and to count mixed collections of $1 and $2 coins and $5, $10, $20, $50 and $100 bills up to $200 (F1.1). The skip counting here (by 2s, 5s, 10s, 20s, 50s, 100s) supports Grade 2 number sense.
Common mistakes:
- Mixing up dollars and cents. Children may write 45¢ when they mean $45. Remind them: bills and the loonie and toonie are counted in dollars, with $ in front.
- Counting a bill as "one". Ask, "What is this bill worth?" before they count.
- Losing their place when switching from 20s to 5s. Sort the money into rows first and touch each item while counting.
- Mixing up bill colours. Practise with homemade play money in the right colours.
How to help: Make play money with your child and keep it for the next lessons. If you have real bills, let your child look at them (with supervision) and find the colour, number and clear window. Talk about real prices in dollars, like a toque or a pair of skates.
