I bought some blue glass stones from the floral section of Dollar Tree and put those on the bottom as "rain drops." I bought one bag, but probably could have used another to fill out the bottom a little more! I placed cotton balls on top of the stones as the "clouds," and then put my cut-in-half rainbow cards in the bin, dispersed among the clouds.
I had my students pull out one card at a time and we identified the concept (“Is coffee hot or cold?”) and then placed it on the table. As students took turns, if an opposite was pulled from the bin that matched a previously-chosen opposite card, I had them find the friend who had a matching card (“Does anyone have the opposite of ‘big?’ Big and….” They would then match up each side of the rainbow to make a full rainbow, and we left the rainbow sets in the middle of the table.
The activity was a hit so I wanted to share it with all of you! I made a set with clouds instead of rainbows, as well, in case you need cards with less visual stimuli. Download it for FREE here in my TpT store! Happy Spring! :)
