These flower table number signs look great hanging above your classroom tables. This set of table signs includes 20 different color choices. Each color choice has 1-5 table numbers. If you need more, let me know : ) They are about 7" in diameter.
They are easy to cut out, you can print two of each color and then glue them back to back. You can laminate them and they will last a long time.
To attach to the ceiling, I use a hand held hole punch to make a hole near the top of the table number and thread fishing line thru it and attach the line with a paper clip or push pin depending on the ceiling.
Here are other group numbers you might like : )
