These icons are designed to help world language teachers to use as little English as possible when teaching.
1) The two person icon means "two person interaction"
2) The three person icon means "interaction among group of three"
3) The seven person icon means "presentation in front of the class"
This is my first product, so you'll see the full set on the next product.
More icons will be added in another set should I see the need to make more.
Please feel free to make any suggestion on how to improve this product. Thank you very much!
