I found a website selling pattern tiles that are modeled after the ones used in child IQ testing (WPPSI®-III ERB, WISC®-IV, Stanford-Binet® 4, Slosson Intelligence Test – Primary SIT-P). Don't know what those IQ test acronyms mean? Neither do I! I just thought these pattern tiles looked like a lot of fun and a neat visual-spatial exercise for my twins (3 years old), but I didn't want to spend the $20 when I figured I could make the same game at home.
I used my photocopier-printer to print out some pattern cards, which I laminated. You could also scan the patterns on a flatbed scanner and then print them out, or just draw your own using some graph paper.
My 3-year-olds were really challenged by this activity and I had to work with them closely to help guide them toward looking at one tile at a time to figure out the orientation..
I love adding brain puzzles to our Homeschool Preschool routine, and my kids really enjoy playing with these types of manipulatives. They're terrific for developing math and logic skills!
UPDATE: I was so inspired by how much my kids enjoyed playing "IQ games" that I created the La La Logic Critical Thinking Curriculum for 3-6 year olds, which includes online brain challenge games, printable worksheets, enrichment activities and more!
