This year for the first time I have set up a snowflake making station. I decided to set this up on my stationary shelf/table so that the children can stand to do each part of the project without having to move materials back and forth from shelf to table. Below you can see the first "stage" of this project.
From top left: a blue bowl to hold the snowflake "clippings", a pan with scissors, a basket of coffee filters (NOTE: I kind of flattened them out as much as possible before placing them in the basket), a jar with a pencil for writing names on the finished snowflake, and a placemat.

I gave a group lesson to the entire class on this project. To do this work, the child first takes a coffee filter and folds it in half "like a taco", then in half again so it looks like "a piece of pizza". Then, they cut pieces from the sides and top, placing the clippings into the blue bowl. When finished cutting, they unfold their paper to see the finished snowflake. At this point, they write their name on the snowflake using the provided pencil. (It wouldn't make sense to write their name before cutting because they might cut it off!! However, if they choose to paint their snowflake, the name needs to be written on first.) Before proceeding to the next "stage", they take the blue bowl to a trash can to empty out their clippings, preparing the work space for the next child.
NOTE: We discovered that it helps some children to have some triangles drawn with pencil for them to cut on. The photo below shows my assistant, Miss Melissa, drawing some guidelines for a student. Some students didn't need this, but this modification allowed more children to be successful. They were so excited to unfold the paper and see their snowflake.
The child can choose to leave their snowflake white OR they may choose to paint it. If they want to paint, the move over to the second "stage" or workspace as shown below.
From left: a dish with a sponge for wiping the placemat after painting, the liquid watercolor paint tray from Discount School Supply (NOTE: I filled the little jars with various hues of blue and violet liquid watercolor paint, made by adding varying amounts of water to the watercolor), a jar of water for rinsing the brush, a butter dish to hold the paintbrush, and a vinyl placemat.

Here are some of our pretty finished snowflakes! I love how they are all unique, just like the little ones who made them.
