Puzzle Doubles from the Learning Journey are two great products in one
 
Step 1: Place all the puzzle pieces with the coloured image side face up have the children assemble the puzzle ( parental involvement may be needed depending upon the age of the child) once assembled the puzzle becomes a ( Talk About) Puzzle as there are many images in the scene to promote parent child conversation,
 
Step 2: After the puzzle is assembled the child can activate the glow in the dark feature by placing the puzzle under a bright light, the brightest glow will come from a UV lamp ( black light) or a fluorescent bulb, turn out the lights and see whats ( glowing) behind the scene
