A calendar is a number line folded into weeks. Filling in the dates helps a child count past 20 and 30, see that the days repeat every seven, and find today on the class calendar. Every sheet is one page of a month: the name of the month on top, the days of the week from Sunday to Saturday, and boxes for the dates. Some boxes are empty, and the child writes the missing dates in order.

Choose the Month, then how many dates are Missing: A few for the first try, Half, or All to write the whole month from the 1st. February always has 28 days here, because the sheet has no year. To match the real calendar, tap the sheet and change Starts on to the day of the week the 1st falls on this month.

The answer key lists the missing dates. Press New sheet for other empty boxes. Every sheet prints in color or black and white, on US Letter or A4. Nothing to sign up for.
