Toothpick art is not just a way to express creativity. It also helps to think geometrically and mathematically and it works on fine motor skills. It also helps abstract thinking. These games combine art with math in beautiful ways.
Ask the children to create the surface of the sea, using matchsticks or toothpicks.
Now, ask them to change the surface of the sea, because “little waves appeared.”
Now, ask them to show you big waves using matchsticks.
Ask them to show you white foamy tops on the waves.
Ask them to show you a weak rain.
And a strong rain.
Ask them to show you how does the rain change direction when the wind blows. Ask them to show you what happens when the wind is strong.
Ask them to show you growing grass.
Ask them to show you grass that has been mowed. The possibilities are endless. Most likely, you will find yourself as interested in the game as are the children. I found that preschoolers can only do the basic part of this game and children older than 5-6 can do it all.
