What is CGI you ask?
focuses on students figuring out the problem solving process. The teacher acts
as a facilitator, and students learn problem solving strategies from each
other. Students use what they already know to build on their learning.
What does CGI look like in the classroom?
There are different problem types that increase in
difficulty. First I introduce the simpler ones, and gradually we get to the
rest of the problem types. The following are examples of joining problems:
four more dolls. How many dolls does she have now?
some more dolls. Then she had ten dolls. How many dolls did her mom give her?
four more dolls. Then she had ten dolls. How many dolls did Jean start out
problems, comparing problems, and multiplication/division problems.
Getting Started with CGI
The first time I give my class a problem, I let them have an opportunity to solve it on their own.
During this time I am walking around, looking at what they’re doing. Eventually someone
figures out the answer. If it’s a really easy problem, several kids figure it out.
Watch the strategies they implement. The goal is to
have them think critically about the process they used to solve the problem, not
necessarily the answer itself (although the process should lead you to the
what he did to solve the problem. At first it is very hard for them to explain
because they are so eager to just give you the answer and have you tell them
how to solve word problems. The first day you may only have one strategy on the
chart. If you do it every day with a different problem each day, you’ll soon
begin adding more strategies as children implement them.
it, you can explicitly teach it. For example, students don’t always jump to a
number line to solve a problem (although I’ve seen it done). Often the number
line strategy is one I have to directly teach.
someone has implemented a strategy. This will ensure students will refer to it
tomorrow, when they are solving the next problem. You can let them know this
chart is here to help us, and we can look at it when we’re solving problems to
help us remember problem solving strategies.
There were five trees. Each tree had three apples. How
many apples were there in all?
solved it. It was interesting to see the way they arranged their blocks. Some
students chose to use blocks, while others drew a picture. The early finishers
re-solved it using another strategy they hadn’t used:
Cognitively Guided Instruction has CGI
problems covering all problem types (from joining and separating to
multiplication and division) already written for you. All your preschool, Kindergarten,
or 1st grade students have to do is cut and glue to their notebook before solving.
You can also just write the problems yourself each day as you go.
