Counting money, the way children learn it
Children first learn to name each coin and its value, then to count a handful of the same coin, and then to add mixed coins by starting with the biggest one and counting on. The coins on every problem are sorted from biggest to smallest to support that habit.
Dollars, pounds and rupiah
Each currency has its own coins drawn to their real shapes and relative sizes: the US quarter is larger than the nickel, the UK 20p and 50p have seven sides and the £1 coin has twelve, and the rupiah set includes the notes children see every day.
