I would like to present a great tool for vocabulary. Observing how many problems are caused by the creation of nouns I decided to create this app to make it easier to practice this skill.
The student types a noun in the right corner and if it is correct, they will get a minimum of 1 point. If it is not correct, then they will lose points.

I wish you fruitful work!!!
