Subitizing & Quick Dots....for Big Kids?

Subitizing, the ability to quickly conceptualize quantity, is an essential mathematical skill. It enables students to connect their innate sense of quantity to numerical digits. Simply counting numbers or writing them down does not equate to a deep understanding of numbers. To truly comprehend numbers, students must grasp their meaning, relationships, and unitization.

Many educators are already familiar with subitizing activities, such as using dot cards, to promote additive thinking and facilitate mathematical discussions. By showing students dot patterns for a brief period and encouraging them to describe what they see, students develop divergent mathematical thinking and enhance their conceptual understanding. Subitizing is particularly valuable for younger students, who benefit from daily exposure to quick dots to develop a strong sense of quantity.

However, subitizing activities are not limited to younger grades. They hold significant benefits for students at any developmental level. Quick dot tasks can be adapted for different grades and help students of all ages strengthen their number sense. By incorporating quick dot activities into mathematics instruction, educators can foster a deeper understanding of numbers and mathematical reasoning across all grade levels.

Algorithm or Strategies

should we teach the standard algorithm in elementary math classrooms? should we focus on math strategies? how do students discover strategies ? what even is a student generated math strategy?
