With this simple yet educative worksheet, you will be able to tell just how much your kids know about the calendar. Do they know that there are many months, weeks and days in a calendar year? Ask your kids if they can recite first the days of the week, and then the months in a year. If they can, they will find this exercise much easier to complete. Read the questions aloud to your kids and help them figure out the answers. Then, instruct your kids to check the correct answers to each question.
