Parents can encourage their children to use ordinal numbers when they are going to the school, or come back home, by asking the child to, e.g, take the first right, third left, the 6th shop on the left, what floor is it on?
And the cardinal numbers:what number is the house? what number is the shop?.
Asking : How many cars..?
How many streets..?
How many people are there at home?
Asking the telephone number: 6-8-7-5-9-0-5
