Note - Many students will solve subtraction problems by thinking of the related

addition fact. For example to solve the fact 10 – 4 =

the student thinks 4 +

= 10. Piaget wrote that this is what always happens in our brain but that over

time we can become so adept at it that it happens on an unconscious level. So

even though these activities are listed as subtraction activities do not be

surprised if the students figure out the answers using addition.

Problem Solving Strategies like this vs. strategies used in CGI.  You will not find a list like this in CGI. CGI is different because instead of giving strategies to students, students give strategies to each other, there is no set list of strategies, and CGI is not about students learning or using one strategy over another, it's about students using their own unique strategies and sharing thier strategy out loud so other student might use it tomorrow.

Our Math Buckets we use during CGI:  There is no set rule about what should go into the buckets, in our CGI Workshop, our table brainstormed possibilities of what could go in there, but they are endless because you never know what kids will need or use to solve a problem.

Math Bucket Tools  After teaching children the proper name of the math tools in the bucket, I laminate this sheet and keep a few in each bucket as they will refer to use correct spelling of tools when explaining their strategies in writing in their CGI Math Notebook. 



On CGI Math days, after I have written the problem, I print 6-8 problems per page and make 4 copies.   I cut them and pass them out after we discuss the problem in our CGI mini-lesson, and the students paste them into the top (date at the very top) of the notebooks.  



I have 4 math buckets because I have 4 hexagon table groups.   The six notebooks for each child at that table are stacked on top of the buckets for storage.   The math buckets are stored in the math supply area when we aren't using them.    After our CGI mini-lesson, the math bucket captain is in charge of leaving the mini-lesson early to get the bucket for the group, distribute the notebooks and take the lid off.  


One of the main components of CGI is the strategy sharing at the end of each lesson.   Students share with the class the strategy they used and how they solved the problem by explaining it to their classmates.   Students must be able to verbalize what they did, what helped them, and how they counted.   The audience can ask questions to better understand their strategy.  I also encourage the share-er to give credit and thanks to the person that first shared the strategy, that they tried and are now using.    I use a karaoke machine for Author's Spotlight in Writer's Workshop, and it worked out for this time of day, too - everyone can hear much better.



 I have a CGI Spotlight poster in the hallway outside our classroom door to highlight students that take risks during CGI, tried a new strategy, showed at least two strategies or did some efficient counting.    I like kids to know that their hard work is being noticed and appreciated.
