The purpose of this Warm-up is to elicit the idea that equal groups appear in many contexts, which will be useful when students create their own Notice and Wonder in a later activity. In the Activity Synthesis, discuss what students know about the Notice and Wonder routine and what they need to think about to create a routine like the example.

• “What do you know about the Notice and Wonder routine?” (It has pictures that help us think about math ideas, like equal groups. We might have questions about what's in the pictures.)
• Consider asking: “What would you have to think about if you were going to design a Notice and Wonder like this one?” (Finding an image that shows equal groups, groups that make counting easier, or different types of groups. Finding an image that shows a missing piece of information, or a group that is different than other groups.)
• Record and display responses for all to see.

The purpose of this activity is for students to collaborate and create a Notice and Wonder routine that involves equal groups. Students find an image in a book, or from another source, and anticipate what other students might notice and wonder about the image.

The purpose of this activity is for students to facilitate the Notice and Wonder they created in the previous activity. Each group takes turns facilitating their Notice and Wonder for another group (or two groups, if time permits).
