My DS7 doesn't like puzzles, and the psychologist who tested her said that was a weakness we should work on as she tends to give up if she doesn't see the answer immediately. She also recommended books where you have to look for something hidden. However, the I Spy books, Hidden Pictures books etc. were not interesting to her at all. I haven't tried Where's Waldo yet.
Things she does like to do that may or may not be helpful in this area- crochet, friendship bracelets, rainbow loom, Mindcraft, origami. Does anyone have any recommendations for how to work on this for her? She still did 99% on the PCI but the psychologist said we should start working on puzzles with her but I'm not sure how to do that.
