free main idea game for practice in kindergarten & 1st grade

This is week 2 of our Animal Groups Science Unit in first grade!  We are bringing a little science into our literacy block with this main idea game by digging deep into inferring the main idea from non-fiction text!

We all know about applying main idea and key details in fiction texts. But sometimes, we leave out this process when reading aloud non-fiction texts. Let’s chat about how we use informational texts to work on main idea and key details in kindergarten and first grade.

Introducing Main Idea & Key Details

We started our main idea game time by reading The Important Book, by Margaret Wise Brown. Have you read this book? If not, you are missing out. There are SO many mini-lessons you can do with this book–not just main idea and key details. But it is so great at helping kids distinguish between details and main ideas.

When we finished reading The Important Book, we filled in this main idea anchor chart together.  

Practicing Main Idea Game

After we read the book and completed our main idea anchor chart, we became inferencing detectives with our main idea bag stations!  I have 6 group tables, so I made 7 main idea bags–1 for each table and one main idea bag for us to model together as a whole class.

We did a practice main idea game bag together first.  I took each detail out of the main idea bag one at a time and said, “This detail is __,” trying to reinforce the language of “main idea” and “detail.”  Then, we did a think-pair-share with carpet partners to figure out the main idea.  After each main idea inference, we went through each detail in the bag and said, “Would a ____ be a good key detail for a ____ main idea?”  For example, “Would a skeleton be a good key detail for a human body main idea?”

I modeled how to neatly write the main idea and illustrate the details on their recording sheet.

Then, they went back as inferencing detectives to their table group.  I told them how important it was to work quietly so they didn’t give away the main idea to other groups. We don’t like to “steal our friends’ thinking” in first grade! They spent 5 minutes at each main idea bag station.

Because we were in the middle of our animals unit AND it was October, I tried to make these tie in with our animals unit or the upcoming Halloween holiday! These are the 7 main ideas I used: human body (for modeling together as a whole group), animals, vehicles, Halloween, toys, school supplies, and shapes.

Once they figured out the main idea as a group, they wrote it on the corresponding number line on their recording sheet and then illustrated and labeled the key details from the main idea bags. (We worked super duper hard on labeling with our skeleton puzzles last week!)  Then, they rotated through all 6 main idea bags. I set a 5 minute timer at each station to keep us on track.  After we finished rotating through all 6 main idea stations, they had a few extra minutes at their desk to color their key detail illustrations and finish any labeling or illustrating they didn’t finish at stations.

Finally, we came together as a whole group and discussed the correct main idea for each main idea bag!  They had so much fun with this!!
