The purpose of this activity is for students to compare groups of images that are lined up. Students compare which group has more or fewer images.

• Display the picture of cups and straws.
• “En cada problema, las imágenes estaban organizadas en una fila. ¿Cómo te ayudó esto a descubrir si había suficientes?” // “In each problem the pictures were lined up. How did that help you figure out if there were enough?” (I saw straws right above some of the cups, but then there were no straws left for the rest of the cups. There are cups under straws, and I saw when there were no straws but there were still more cups.)

The purpose of this activity is for students to compare groups of images. The images are organized in lines, but the objects are not directly matched, which requires students to match or count the images to compare. Students are asked “Are there enough?” before they compare to encourage them to think about matching the images. In the Activity Synthesis, drawing lines to match the images is highlighted. Matching the images helps students relate the comparisons to the situation they just worked with where the images were already matched (MP7).

• Invite a previously identified student to share how they drew lines to match.

The purpose of this activity is for students to learn Stage 1 in the Math Stories center. Students take turns asking “how many?” questions about pictures. They work with a partner to count groups of images in different arrangements to answer their questions. For example, students can ask, “How many basketballs are there?” or “How many kids are there?” or “How many shoes are there?” In a future variation of this center, students will record how many images they counted with a written number.

After they participate in the Math Stories center, students choose any previously introduced stage from these centers:

• Connecting Cubes
• Number Race

Students will choose from these centers throughout the section. Keep materials from these centers organized to use each day.

• Display this image from the Math Stories blackline master.

  

• “¿Cuántos pájaros hay en la imagen? Cuéntenle a su compañero cómo lo descifraron” // “How many birds are in the picture? Tell your partner how you could figure it out.”
