Because why not?
I love logic puzzles and think they are great for students to promote playful, logical thinking and problem solving.
The amazing Sarah Carter of Math = Love very generously shares puzzles that she uses in her classroom on her blog, and I've found time to print out two so far and put them in my room for students when they have a spare minute or two.
The first one is the A+ puzzle, which can be really tricky unless you approach it in the right way.
Then I added in the 1-4-5 Square Challenge.
Of course, I put it right by my Deutsch macht Spaß sign!
I think it's about time to rotate out the A+ puzzle and bring in a new one - as soon as I find the time!
