Standard Unit Blocks

Block sets are a classic that never go out of style, and FamilyEducation.com notes that blocks allow kids to “master math concepts about shapes, space, balancing and gravity.”
— “Wooden blocks by Melissa & Doug” were expected to be a 2006 holiday hit at The Name Dropper in Montgomery, Ala., owner Shea Schroll told TDmonthly.
— “Standard building blocks by Melissa & Doug … we sell those every day,” Peter (Mr. Toad), owner of Mr. Toad’s Toy Company in Naples, Fla., told TDmonthly in April 2008. Erica Welton, manager of Bedford Falls Toy Store in Charlotte, N.C., said her store sells “two or three sets a day.”
— More than 17 percent of retailers who spoke with TDmonthly in spring 2008 named this item as their best-selling construction toy.
