Adding basic facts is too easy! Can we try the hard level?

Today during Pickles and Ketchup time, a group of my students were using the SMARTBoard to play Callum's Addition Pyramid.  If you don't know about this resource, you've got to check it out!  Click on the picture to visit the site.

It's an addition game with three levels of play, easy, medium, or hard.  After each turn, you can choose which level you want to play.  Easy is basic facts, and typically, my kids start there.  But then they get adventurous and want to try medium and hard.

Today, about 5 of my kids decided to play on the hard level, and it was so cool to watch the different ways they tried to figure 17+19.  One boy was trying to count on his fingers.  One of my girls got out the cubes.  Ben realized counting on his fingers wasn't going to work, so he started helping Jules count cubes.  In the meantime, Alaina and Shelby decided to use the number line above the chalkboard.  It only goes to 30, but Alaina was finally the one who came up with the answer using the number line!  Anyway, the game is really cool and easy for the kids to get the hang of.  Try it out!

What are some ways your students solve difficult addition problems?
