Sometimes we just have so many random toys laying in buckets that I thought it would be fun to collect a “rainbow” to play with.
I had my kids find different small toys of red, green, yellow and blue and sort them in a bin and then they were able to play with those toys together.
It was fun to see old toys become new in a “rainbow” sort of way. So if you are thinking, “how can I combine toys?” — this activity does it for you — by color!
