CGI Mathematics A Research based Approach

CGI Mathematics
A Research based Approach

Here is what I've learned so far...
First, it's not a curriculum.  It's more an approach to teaching math. 
Guiding Principle
Make sure kids explain their thinking.  Give them time to explain how they got their answer.  They may not have gotten there how you think.

Things to think about!
How can we create ways to allow kids to participate? Allow for all different modalities and preferred methods for tackling math.  We want all kids (and adults) to feel competent in math.  Let students put the work together as they wish.  Say you tell them to take out 12 blocks... they can organize in a line, groups, a mix up- let them do it as they wish.  If you stop them, it can gum up the works!

Build on strengths instead of focusing on weaknesses.  Stop returning papers with all the wrong answers circled.  Let's look at what they did right instead.   That is a big aha for me!  Build on what they understand!

Overarching idea
We want kids to become great problem solvers!  To be successful at applying mathematical skills at real world problems.

Big Findings:
Explain your thinking orally or in writing
Explaining your thinking to others helps you and the other person too!
It integrates well with Eureka Math too, which is great since we are implementing that this year.

Here are a few of the CGI math resources I've made to use in my classroom- fourth and fifth grades.

  1. This reminds me so much of all the good parts of Bridges Math - Explain your thinking, try different approaches, and focus on the right answers. Wonder if the games component of Bridges would go well with CGI also. Great and informative post!

  2. Thank you for this new approach to math. I have never tried CGI math before, but it sounds as if it would flow beautifully with my current math curriculum. Here's to a wonderful school year!

  3. I find the concept of CGI math fascinating. I am an English and creative writing teacher, so I am always looking for new and better ways to teach math to my grandson. Thanks for this interesting post.

  4. It is amazing how much students know as long as you give them a chance to explain how they tried to solve a particular problem. Then the teacher can help guide the students to the parts of the process that they missed.

  5. These are great tips, Lisa. I'm teaching math again for the first time in 20 plus years, as we returned to self-contained (virtual) classes this year, so any expertise is always appreciated.
