Giving children coloring activity should be the best way to refresh for all the learning lessons in the entire day. I am sure that your children also love to do coloring task. My children also really feel excited while they are in coloring time.
I always give the different theme of the coloring page like fall color pages. This kind of the color pages are best and good for children under the age of 5. My 3 years old kid loves to color her favorite color pages.
