5. How many days in 3 weeks?

6. On what day of the week will your next birthday be, etc.

Remember:

The days of the week in their order.

The months of the year in their order.

Procure a calendar for the child to own.

A good way to make him familiar with the use of the days of the week and month, as found on a calendar, is to ask him to look up and tell on what day of the week the next Fourth of July will fall; Christmas; New Year; his birthday.

Have him distinguish between the day of the week and the day of the month.

7 days make 1 week.
30 days make 1 month.
