Kid Lego Inventor

March 3, 2017

It’s exciting when people invent a cool new tool. But it’s even more exciting when a kid invents the first one using Lego. A California mom got tired of the clutter in her bathroom — hair dryers, curling irons, electrical cords. So she jokingly asked her son Jack to build a cabinet out of Lego that would hold all these weird shapes. Jack built a pretty great one, so the mom made a new one out of regular plastic, and entered a TV contest called Homemade Millionaire. Their invention won the contest! Now you can buy the “Style ‘n Go” in real stores. So what will Jack build next?

Wee ones: How many pink things can you count in the n Style ‘n Go picture?

Little kids: What shape are the Lego bricks in the top photo?  Bonus: If his Lego invention used 100 pieces of red Lego, 100 blue, 100 green and 100 yellow, how many pieces did it use? Count up by 100s!

Big kids: If Jack had 20 long Lego pieces, and wanted the same number of pieces in each shelf, how many different size shelves could he build?  Bonus: If Mrs. McKenna makes $100 on each Style ‘n Go she sells, how many does she need to sell to make $1,000,000 (1 million dollars)?




Wee ones: 5 pink items.

Little kids: Rectangles, or in 3D a “rectangular prism.”  Bonus: 400 pieces.

Big kids: 6 sizes. This is a factoring problem: the shelves can each use 1, 2, 4, 5, 10 or 20 pieces.  Bonus: 10,000 Style ‘n Gos.
