What this review covers: counting and representing the same amount of money in different ways, up to 200¢ with coins and up to $200 with $1 and $2 coins and $5, $10, $20, $50 and $100 bills (F1.1), plus problem solving and perseverance (A1).
Which lesson to revisit:
- Mistakes counting coins, especially counting by 25s or counting past 100¢ (quiz questions 1 and 2): go back to Counting Coins up to 200¢.
- Mistakes finding equal coin values or the fewest coins (quiz questions 3 and 4): go back to Same Amount, Different Coins.
- Mixing up bill colours, or mistakes counting bills and dollar coins (quiz questions 5 and 6): go back to Bills and Coins: Counting Dollars to $200.
- Mistakes finding equal dollar values or the fewest bills (quiz questions 7 and 8): go back to Same Dollars, Different Bills.
- Mistakes deciding if there is enough money or paying exactly (quiz questions 9 and 10): go back to Solving Money Problems.
Watch for these mix-ups: thinking more coins or bills always means more money; writing ¢ when they mean $ (or the reverse); and counting each coin or bill as "one". Ask, "What is each one worth?" and have your child count again starting with the money worth the most.
How to help: Keep the play money handy. Short games of "store" and "bank" a few times a week will make these skills stick.
