Fun ways to tech your kids Weekdays and Months:

During the week, put first letter of the name of the Weekday to the sneakers on both sides. Put "M" if It is Monday, "T" if it is Tuesday and so on. You kids will see the letter all the time and will remember the Weekday.

Same could be done with Months. You can put the first letter of the Months so your kids could learn it.
