ThinkBlocks are cool!

Came across this site via Google Ads, and I'm glad I did.
I am very impressed. Check out ThinkBlocks. Here is a little blurb from their site ...

Think outside the blocks

Learning to think is absolutely essential. The unique design of ThinkBlocks teaches four universal thinking skills:

• Distinctions: Learn to make to compare & contrast between similarities & opposites
• Systems: Learn organizing, sorting & part-whole thinking skills
• Relationships: Learn about interactions, associations, cause & effect
• Perspectives: Learn to take different points-of-view
