I didn't have a full set of blocks so I couldn't use their template, but I made my own cards to fits the colors/sizes that I did have and it was a HUGE success with our pre-school co-op. My 4 yr old loved playing with them for days after that pre-school lesson and his friends that have come over to play loved it as well.

TODDLER TIME ACTIVITY: POPSICLE STICK PUZZLES = it is easiest to tape the popsicle sticks to the table with masking tape to keep them together, then glue pictures on with Elmer's glue, and let dry. Cut between the sticks with an x-acto knife. Pictures of family members and pets with their names added underneath with a Sharpie are especially fun to put back together!!
