What This Standard Means
What Students Need to Do
- Students find dates on a calendar and tell when events happen. They count forward or backward to find the number of days or weeks between events.
What Mastery Looks Like
- A student can locate today, yesterday, and tomorrow, then identify the correct week and month. The student can use calendar squares to count elapsed days or weeks.
Common Misconceptions
- Students may count the starting date as a full day when finding elapsed time. They may think every month has the same number of days or confuse a week with the school week.
How to Assess It
- Give students a monthly calendar and ask, “The class trip is on May 18. How many days after May 12 is the trip?”
