Number Sense

What is number sense?

• ·        Quantification (specific set of objects)
• ·         Number identification (naming numbers)
• ·         One-to-one correspondence
• ·         Composing numbers
• ·         Decomposing numbers
• ·         Understanding the number system (how numbers relate to each other)
• ·         Ability to use mental math
• ·         Understanding of math symbols

***Typically by age 4, students can recognize groups of 4 instantly. It begins at the age of 2 where children can instantly recognize sets of 1, 2, 3 objects. I have seen this with Nikolai – he will look out and see 2 birds and say “There are 2 birds over there.” Without even counting 1, 2. Pretty neat!! This subitizing was established by Piaget.

Why is it so important?

Number sense skills in the early years is a strong indicator of overall mathematics achievement. (Teaching mathematics in Early Childhood)

A strong foundation in number sense also teaches children to be flexible in their problem solving. In this, children learn that numbers are meaningful and despite manipulation, their outcomes are constant and sensible. *Teaching Preschool and Kindergarten Math* On the other hand, children who lack in number sense skills have difficulty performing even the most basic mathematical algorithms.

How is it gained?

Through lots and lots of practice within authentic experiences, or at the very least situations that simulate authentic experiences.

Mathematical experts are recommending moving away from straight pencil and paper computation, which does little to boost a child’s critical thinking skills, and rather the latest movement in math education is providing children with multiple hands-on strategies for solving problems.
