I’ve found these different colored snowflake pictures on Google Images to use for sorting and patterning. You can print out two or three copies of each picture cut them out and laminate them for sorting and patterning cards.
There are three patterns below as examples, but they can be arranged however the kids want. Patterning cards are good for beginners to learn the simple A B pattern, but they can be used for more complicated patterns as well. These can also be used as matching cards or to simply learn about colors. You could also find additional pictures of snowflakes that have different characteristics to pattern and sort with.
