Math and art come together. A tessellation is a shape that can be repeated over and over in a pattern with no space in between.
Start with print out the template.
It’s easier to color the trees before you cut them out. I glued on all our trees on poster board in the tessellating pattern. (Kids can totally do this themselves – it just may not line up q
uite as nicely as mine!)
When you glue them down, let the black lines overlap between trees.
It’s easier to glue down your trees if you draw a straight line as a guide.
If you feel for a collaborative project, make a big Christmas tree out of all the small ones. My Christmas tree below is made out of 64 small ones. That will make a tree of approximately 80 cm height.
