I’ve dipped my toes in Twitter lately (as part of the Explore #MTBoS program) and been swept up in a crashing tsunami of information. There’s no way to keep up with it all, but I’ll let the tide wash over me and enjoy the tidbits I happen to notice as they float by. For instance, yesterday I discovered a writer who offers tip on writing about injuries and was able to get some great advice for Kitten’s sequel to her first novel.
And then today, Steven Strogatz posted a link to Saramoira Shields, a new blogger I might never have discovered on my own. I think you’ll enjoy her video:

Here’s one more entry for my 20+ Things to Do with a Hundred Chart post, thanks to David Radcliffe in the comments on Monday’s post:
(30) Can you mark ten squares Sudoku-style, so that no two squares share the same row or column? Add up the numbers to get your score. Then try to find a different set of ten Sudoku-style squares. What do you notice? What do you wonder?

This was a fun activity from Moebius Noodles for our PK-1st grade Homeschool Math in the Park group. The children take turns making a maze and setting a dinosaur inside. Then the other dinosaurs (parents or siblings) try to guess whether their friend is on the land or in the water.
Player #1
(1) First, draw a big circle on the white board. This is your lake.
(2) With a finger or a bit of cloth, erase a small section of the circle to create the opening for your maze.
(3) Starting at one edge of the opening, draw a random squiggle inside the circle. Make your squiggle end at the other edge of the opening.
(4) Set your dinosaur anywhere inside the maze.
Player #2
(1) Now it’s your turn to guess. Is the dinosaur standing on the land? Is it swimming in the water?
(2) How will you figure out if you guessed right?
(3) Check by jumping across the lines of the maze. Each jump takes you across a boundary: Splash! (Into the water.) Thump! (Back on the land.) Splash! Thump! … Until you reach the dinosaur inside.
(4) Or go to the maze entrance and walk your dinosaur along the path. Can you find your way?
