Find how much money is left
Working out what's left is the moment money starts to feel real to your child. If they have 75¢ and a sticker costs 40¢, they can tell you there's 35¢ to spend on something else. These problems turn subtraction into something useful, and they build the careful checking that saving and spending need. You'll see it with pocket money, at a lemonade stand, or in the change at a corner store.
In this video, your child will learn to find how much money is left.
The lesson stops at each question for your child's answer.
Three problems, each a little harder
Each problem is worked step by step. Your child will solve the last one before Bobby shows how.
Example 1
Ana has 3 dimes and 4 pennies. She spends 14¢ on a sticker. How much money is left?
Example 2
Leo has 1 dollar bill. He spends 60¢ on a ball. How much money is left?
Your child's turn
Kim has 1 dollar bill and 2 dimes. She spends 50¢ on a pencil. How much money is left?
The three key steps
- 1Count what you have
- 2Cross out; trade if you need to
- 3Count what's left
Mistakes to listen for
- Adding the price to the money instead of subtracting, so having 80¢ and spending 30¢ seems to leave 110¢ instead of 50¢.
- Treating a dollar as 1 instead of 100 cents, so the change from $1 for a 60¢ snack seems impossible to find.
- Giving only the last coin as the change, so counting up from 70¢ to $1 gives 25¢ instead of 30¢.

What happens when my child answers a question?
A right answer gets a cheer, and the lesson carries on. If your child isn't sure, they can tap "I don't know yet", and Bobby gives the answer and shows another example. Nothing is scored or stored.
Is this the same lesson that's on YouTube?
Yes. Here, the lesson stops at each question and waits for your child to answer. On YouTube, each question stays on screen for a few seconds, and then the lesson plays on.
