This PDF includes materials to create your own calendar. It has spaceship and star theme numbers, days of the week labels and month labels. For some extra fun, decorate around the spaceship for each month. For example, put snowflakes around the December spaceship or flowers around the May spaceship. This document does not contain a template for a calendar.
I have several other space/star theme materials available. Please visit my store at http://www.teacherspayteachers.com/Store/Heather-Meinen-Designs.
