What you'll need:
One sheet of construction paper per child
1" x 1" pictures of menorahs
1" x 1" pictures of the kids preparing for Chanukah
a single 2" x 2" picture of each child
Fold a sheet of paper in half and draw half a menorah so that when you cut it out and unfold it you have a full menorah. Half the menorah would be 4 branches and a half of the shamash. cut out the menorah, making sure that you now have a complete menorah frame, and the actual paper menorah. Following the preparations for stained glass, cover one side of the menorah frame with contact paper. Set the menorah cut out aside for later. Then, give each child his/her larger photo to place face down in the center of the menorah. Once every child has his/her photo down, show the kids to stick on the various menorah pictures as well as the pictures of themselves getting ready for Chanukah. Once they've filled the menorah, cover it with a second sheet of contact paper. Now you have a fantastic menorah mat that's sure to be saved and cherished of years to come!
As a separate craft, you can take the menorah cut out and have the kids decorate it either by painting, doting, coloring, etc. Then, provide the kids with the Brachos (Blessings) printed in Hebrew and transliterated/translated depending on the community you are catering to. Laminate these with contact paper too!
