Here’s my semi-annual plea to buy building sets for girls. While I don’t really see the need to color code such building sets, if pink is what will do it for you or the girls in your life…go for it. You can buy CitiBlocs new Hot Colors set. LEGO also offers a bucket of pink bricks (read our review here).  If we want our girls to excel in math and on their standardized math tests…part of that comes from playing with blocks. Spatial relations, visual discrimination and other essential skills that are key to success in math, engineering and architecture all begin with being exposed to construction toys as kids.  Not to mention that such open-ended sets are great for developing your child’s sense of what can be.  For a full review of CitiBlocs, click here.
