Many young children like to color in the various spaces in order to discover the hidden image. It is also a great way to introduce stained glass activities in art class. Cross curricular activities are said to pique the interest and reach more children.
Sometimes the success or dismissal of an activity lies in the way it is presented!
Please let me know how you like this sort of learning activity. To me, it is one of the most difficult to create. However, I am happy to do it, if there is a call for it! Thank you!
