I came across this brilliant idea for sunbleached puzzles. They were so easy to create and great entertainment (and practice) for a puzzle-lover. It was also a great little lesson in the sun’s effects.
I set out foam bath letters and numbers on dark construction paper and left them to sunbathe awhile on the deck. J enjoyed watching the process, impressed by the magical results! We then brought it all inside to start putting it all together. You can make this activity more difficult by adding extra foam letters to the choices.
This is great practice at letter recognition. It’s also great way to help them learn how to spell their name, memorize their phone number or address.
The link above used magnetic letters and shape blocks to create their puzzles. You could also cut your own shapes out of colorful foam.
