It's So EASY When You Put It That Way

My 6th grade math class isn't as ready to be fully entrenched in the #gamification, but we still play plenty of games.  We just don't do the leaderboard, experience, or player character aspects - there are no NPCs (Non-player characters), and they don't collect items.

I haven't ruled out doing this later in the year, however.  In fact I have penciled in a quest where the 7th graders have to rely on sixth graders for important information.

Today I introduced the concept of combining integers.  Amazingly, I did it with a game.  Shocking, I know.   Students logged on to an interactive number line maker (there are many, I used this one) and let students play around for a bit.  After they became comfortable using the page I instructed them to create a number line from -20 to 20 that counted by ones.  I then had them move their circles to zero.

Students were organized into teams and they saw that I had spread out a deck of cards on the front table.  I explained that I removed the face cards from this deck, and so that the card values of two through ten were available.

I then explained the rules of the game.  Each student would be chosen, one at a time, to pick a face card.  Black cards represented positive numbers and red cards represented negative numbers.  We reviewed that positive numbers were on the right and negative were to the left.  They quickly made the connection that if they pick a black card, the number would move right, and a red card would move them left.

The first team to positive 20 points wins the game.

Students came up one at a time, picking their team's starting card.  From there they moved their virtual number line to their starting place.  As more cards were picked students realized black cards were always good and red cards were always bad (in this game anyway. I hinted in a future game they may want the negative cards!)

What they didn't realize is they were learning how to add integers.  I specifically instructed them to not use words like "adding" and "subtracting."   Later in the week when I introduced the vocabulary and concept, they were blown away how easy adding integers was.  We talked about how this was addition (even though negative cards "subtracted" the value" because we were always adding cards to their collection.  Later in the week I gave students a check-out (formative) assignment and nearly the whole class scored 85% or higher.

When I get back from AMLE 2016, I plan on introducing subtracting integers with a similar game - students will start with cards and get to discard to get to a target number.

I'm off to Austin tomorrow for AMLE!  'll be arriving on Sunday and my session, Building Simultaneous Engagement, will be on Wednesday at 11:30 am!  Hope to see many of you there!
