The purpose of this activity is for students to count and compare groups of up to 10 images arranged on 5-frames. Because the images are on separate cards, it is more difficult for students to use matching to compare the groups of images. Students may use the arrangement of the images to help them to compare (MP7). For example, when looking at 2 groups of images on 5-frames, students may notice that one 5-frame is full and the other 5-frame has 2 extra dots under the 5-frame. Students will use the same set of cards in the next activity.

• Display two cards:
  

  

  
  

  

• “Which card has more dots? How do you know?” (This card has more dots because they both have a full 5-frame, but this one has extra dots underneath.)
• 30 seconds: quiet think time
• Share responses.
• “This card with 7 dots has more dots than this card with 5 dots. This card with 5 dots has fewer dots than this card with 7 dots.”
• “Sometimes we can use the arrangement to help us figure out which group has more. The 5-frame is the same on both of them, but 1 card has some more dots in the bottom row.”

The purpose of this activity is for students to compare groups of dots arranged on 5-frames and fingers. Students use the 5-frame cards from the previous activity and show a number of fingers that is more than, fewer than, and the same number as the number of dots on the 5-frame. The Activity Synthesis highlights the connection between the 5 structure of fingers and 5-frames.

• Display card: 
  

  

  
  “How many hands do you need to use to show fewer fingers? How do you know?” (1 hand. The 5-frame is full, so there are 5 dots. 1 hand has 5 fingers, so we need fewer fingers than that.)
• Display card:
  

  

• “How many hands do you need to use to show more fingers? How do you know?” (2 hands. We can show 5 on 1 hand, but then we need more fingers.)

The purpose of this activity is for students to learn Stage 1 of the Bingo center. Students identify groups that have the same number of images. The images are presented in a variety of arrangements, such as in lines, arrays, and dot cube arrangements, and on fingers and 5-frames. Students may recognize the number of images without counting (subitize) or may count the images.

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

• Math Stories
• Connecting Cubes
• Number Race

• “How was your partner or group able to help you when something was challenging during centers today?”
