We've canned the plagues for you so you can open the box to narrating the story of the Ten Plagues with Seder props. There is a cute Passover toy for every one of the Makkos. Children won't forget the Pesach story so fast, as they play with the contents of the Passover Can of Plagues.
Let their imaginations out of the can, by opening up concrete understanding of what the Exodus was about. Teach your children at your Seder Table. And use visual props to help make the Passover story more fun for them.
"And you shall tell your sons..." is an obligation on the Jewish parent. Go ahead, tell them the story. And let them pantomime it with the Pesach toys found in this Pesach can.
