Money
Money maths means counting coins and notes, adding up prices and working out change. Most currencies split one unit into 100 smaller ones, like 100 pence in a pound.

Children add prices and work out change by counting up from the amount spent to the amount paid.

Hold up three coins of different values. "Which is worth the most? Is the biggest coin always worth the most?" (In many countries it isn't.) Then make 20 with coins in two different ways and ask children to find a third.
Set up the toy shop with labels: a pencil 4, a ball 9, a book 13. Use your local currency; the method is the same with pounds, dollars, naira, rupees or euros.
"I buy the ball and the pencil. What's the total? 9 + 4 = 13. I pay with a 20 note. How much change?"
"I count up from what I spent to what I paid, like a shopkeeper. Start at 13." Draw jumps on a number line: 13 to 15 (2), 15 to 20 (5). "2 + 5 = 7. My change is 7."
Step by step
Do one more: a book and a ball (13 + 9 = 22), paid with 30. Count up: 22 to 25, then 25 to 30. Change is 8. Check: 22 + 8 = 30.
"Why count up instead of taking away? Because it's how shops really do it, and it's easier to count up in friendly jumps than to take 22 away from 30 in your head."
