Other Examples:

  • A child rolls a pair of dice and knows there are 7 dots because they see a 2 and a 5.
  • The child says, "I rolled seven; I saw 5 and 2 and so it's seven!"

Help your student become a(n) Conceptual Subitizer to 7

Activities throughout the day naming the number in sets up to 7 and especially short, frequent, game-like opportunities to name the number in sets in different arrangements (such as a group of 2 next to a group of 3) only seen for 2 seconds or less help develop children's ability to quickly see a whole number by perceiving two parts. Two different colors may help children initially distinguish the two parts, but they may limit children's creativity in how they partition the objects, engendering rich discussions. So simple identical objects are often the best choice.
