Easter is the most significant day for Christians, but kids, especially the very young, have no real insight into theology. What they understand is happiness. Doing fun activities is a way of bringing out that happiness. And, in a sense, it does give them an appreciation for Easter that can develop into the proper understanding of the day later in life.
The problem is we are not all skilled at doing crafts, at least in developing the craft ideas. Nor are we all skilled at designing activities. With a little help we can handle these crafts and activities.
Working on the ideas is not difficult, and when helping children it is best to step back and allow them to take over. You might give instructions, but if it fails to meet what you expect that is fine, it is about the accomplishments of the children. Furthermore, it is a great bonding opportunity.
