Days and Months: Using a Calendar

About This Resource

A free Grade 1 math worksheet on using a calendar. Children learn that a week has seven days and a year has twelve months, name the day after and the month after, put days in order, count days forward and mark a special day. Includes a timed lesson plan, a six-activity worksheet, an editable Word version and answer key.

Overview

A calendar helps us plan and remember special days. Children learn the order of the seven days of the week and the twelve months of the year, and use the class calendar to answer questions: What day will it be tomorrow? Which month comes after June? They count on one or two days, put days in order and finish by marking a special day of their own, such as a birthday or a class trip, on a calendar.
