Hi just a Mum:
But here are a few ideas...
Make snowman decorations but have the two circles of the snowman be part of a making circles exercise:
Teaching them how to make a circle with a compass
learning terms like diameter/ circumference.
Learning about pi (without really realising it) - have them see if they notice anything about the width of the circle (the diameter) - vs. the circumference of the circle (the edge of the circle).
They should notice that no matter what the size the circumference is a little over 3 x as long as the diameter. In fact this term is called pi (can't make greek symbol for the letter Pi).
Then let them decorate snowmen with glitter & draw faces. You can punch hole in top and put through ribbon to make them into ornaments.

Baking?
why not get 2 circle biscuit cutters - one large for body/ one small for heard
have the children measure & make the dough
Roll out the dough
decorate snowmen (chocolate sprinkles, coloured sprinkles, etc...)
and
bake
Have more able Y2's calculate what time it will be when the biscuits are ready.
Have able Y1/ Y2 calculate how many biscuits made in total if each cookie sheet holds 12 cookies and X many sheets were baked.
Have Y1/ Y2 play game with simple division of snowmen biscuits. I have 12 snowmen cookies and want to share them to 3 reindeers. I also have promised them that they will all get the same number of biscuits. How many biscuits does each reindeer get?

Lesson on properties of water
liquid/ solid/ gas (steam)
liquid: with hot chocolate
with squash
solid: freeze water (use shaped ice cube trays or moulds)
make jelly (in appropriate winter mold - ?snowman mold)
steam: have someone place a small mirror or their glasses over the hot chocolate mug (notice the steam) - talk about seeing your breath in the winter, etc....
