I'm linking up with Second Grade Sugar and Spice for my first ever Wordless Wednesday! I can't be entirely wordless--that just isn't my personality! :)
My first graders have become obsessed with creating "number puzzles" for each other on white boards. I love it because it gets both students (creator and solver) really thinking about one more, one less, and 10 more and 10 less! But the real reason why I love it is that there is absolutely NO PREPARATION on my part involved in this game!
Do you have any popular no prep games? I'm always looking for something new!
