Year 1 Christmas maths worksheets
A free 3-page Christmas maths booklet for Year 1, set in an Australian summer Christmas. Addition facts and story problems within 20, halving a collection, skip counting by 2s, 5s and 10s, and using a December calendar to count the sleeps until Christmas Day. Print it for the class, turn on the answer key for marking, or switch edition for a fresh set with the same skills.
How to use it in class

- Model the first story problem on the board with a number sentence, then let students work in pairs.
- The calendar questions pair nicely with a real December calendar on the wall.
