Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

Cyberchase is a math cartoon on PBS Kids GO! Cyberchase features the Cybersquad who use math and problem solving skills in a quest to save Cyberspace from the evil villain named The Hacker. Jackie, Matt, Inez, and Digit (the characters comprising the Cybersqud) are zapped into Cyberspace by Motherboard, the ruler of Cyberspace. Also in Season 8, Ledge another evil villain decides he can take over cyberspace without The Hacker.
Each episode ends with a live-action For Real segment, hosted by young, comedic actors who explore the show’s math topic in the real world. Cyberchase is created by Thirteen Education for WNET aka Channel Thirteen.
After the 5th Episode of Season 8, "Cyberchase" was cancelled, due to executive reasons.
