# Earth Day Math: Partner Problem Solving

Looking for an easy math lesson idea to help you get some much-needed one-on-one time or small group time with students?  See what you think about this Earth Day math activity!

### Earth Day Math Problem Solving

I always have a pocket chart or two on my wall where I keep word problems or other challenges at all times.  I can change these out to be more seasonal, to be more review, or to match the topic we are studying.  In this case, I loaded up this anchor chart with some Earth Day problems!

It’s testing season so I am having to switch my schedule all around and squeeze in math throughout the day.  One thing that helps me do this is having a ready supply of challenges ready to roll so students can work cooperatively and I am freed up to pull small groups for coaching.  Those “wall problems” sure come in handy!  Right now we are wrapping up our big division unit, and I still have a large handful of students who really need some one-on-one coaching.  While I pulled them today, I let the others work on these fun Earth Day problems–which were quite challenging for them!

My only direction was that I wanted them to work ALONE to try solving the problems first–

### Partnerships in Math

–and then to partner up to compare NOT JUST ANSWERS, but strategies as well.  I encouraged them to “teach” the partner the strategy they used so they could see a new way of solving the problem–and you should have HEARD the discussions!  It was super cool to see some groups really putting their heads together and studying each other’s notebooks.  I heard things like…

and
“I can’t believe you were right–I was positive I was!”
and
“Never mind–I totally see what you did now.”

We spent about 30 minutes working on Earth Day math problem-solving and it allowed me to meet with 1 small group and 8 individual students for error analysis on their exit slips!  (Not sure what I mean by this?  When I give an exit or entrance slip, I quickly sort into “got it” and “oh boy” and then pull students to study their work.  If they are making careless errors, I ask them to “proofread” and try to find their errors.

If they are struggling with the content, I reteach them either one-on-one or in a small group.)  I love having these slips handy for whatever I’m teaching…they really help me keep taking the temperature of the class in only a few minutes!  Click HERE to learn more about my formative assessment slips.  Interested in the Earth Day problems?  Click any other image or RIGHT HERE.
