In a calendar riddle you calculate with days and weeks.
Here is how:
1. Read carefully which day the story starts on.
2. Remember: a week has 7 days.
3. Example: Today is April 3rd, in 3 weeks it is 3 plus 21, so April 24th.
The filled in number shows the answer.
Example
1. 24
For parents
What does this exercise practice?
Calculate with days and weeks and confidently work out time periods on the calendar.
Common pitfalls
Children often count a week as 5 school days instead of 7 days. Clarify the length of a week out loud before calculating.
How to practice at home
Using the family calendar, work out together how many days are left until the next birthday or outing.
