I made this weather set for my classroom calendar. I use it with Pre-K, but it is really more appropriate for first and second.
Set includes a display for the weather (I laminated), a chart to graph the monthly weather (I laminated; use wet erase marker to reuse monthly), 10 pieces** (hot, cold, cool, warm, sunny, cloudy, rainy, snowy, foggy, and windy), and a weather sign language chart
**Use Velcro dots to place pieces on and off display
