What's My Function?

The bottom x value is a 3.  It isn't very clear.

A few years I switched schools and in that move, lots of stuff ended up in my office area at home while it waited to go to it's new home in my new classroom.  Well, some of it never made it and after looking at it for the past 3 summers, I finally decided that it was time to dig through what was in the boxes and start organizing or throwing.

Here is a little gem that I came across in the files.  Writing the function rule from a table was a challenge for this particular class, so I had them make these cards.  Everyday, a new student posted their function table and the class worked to figure out the rule.  We then posted it for students to use for review on their own.  It was great practice, but it took a lot of time!  I think that is why is is still sitting in the file because it would impossible that I just forgot about   it! : )

I started thinking about this because I liked the premise of what I did.  So I came up with two alternatives to use instead.

1) Students would find a new partner each day and practice finding the function rule of their partner's card.  It would allow the opportunity for the students to practice coaching.  Also, it gives them an opportunity to explain their thinking and get clarification from a peer if needed.

2) Students could put the same information onto an index card.  They could do a mix 'n' match with them.  I could collect the cards and redistribute everyday and do a quick 5 minute review.  The index cards could also go into a station activity at a later time.

There are probably more ways to use this that my summer brain isn't coming up with yet.  Does anyone else have an idea of how to use this in the classroom?
