Comparison

Supporting Mathematical Development in Young ChildreN

This video describes children's ability to compare two groups and notice if one has more or less. It also provides examples of how early childhood professionals can both explicitly teach this skill and support its development through daily routines and play.

    Dr. Sudha Swaminathan, Eastern Connecticut State University: Comparison is an important aspect in number sense. Because fundamentally, when we count, we have a purpose. We’re trying to determine if we have enough, if we need more.

    Caregiver: We’re building a fort.
    Child: This is more.

    Dr. Sudha Swaminathan: So comparison leads us to think about that intentionally. So when you have two groups—say, a group of four and a group of three—you want children to be able to determine which group has more. And originally, they might count the numbers, and they start to compare those quantitatively. Sometimes they compare it visually. Which looks like it has more?

    Child: That one’s big. That one’s little.

    How Can You Help Children to Make Comparisons? (1:08)

    Narrator: Adults can support children’s ability to compare amounts throughout the day.


    Supporting Math during Routines (1:19)


    Narrator: Daily routines provide opportunities to practice this skill in meaningful ways.

    Teacher: Somebody talk to me about those numbers. We’ve got four boys, four girls.
    Child: It’s the same.
    Teacher: It’s the same number.

    Yotisse Williams, Preschool Teacher, HCC Early Childhood Laboratory School: Lunchtime even, you know, some of the kids have fruits and vegetables, and we were counting the number of fruits and the number of vegetables. Who had the most, who had the least?

    Integrating Math Learning in Play (1:45)

    Narrator: While exploring materials, children naturally encounter differing amounts.

    Dr. Sudha Swaminathan: So when they’re playing with play dough, and they have a lot of play dough, and someone else has a little bit, they’re able to make those comparisons.

    Boy: Mine is getting higher than yours.
    Girl: Yeah.
    Boy: Don’t you know that?
    Girl: Yeah.

    Narrator: Adults can support children to make comparisons during play.

    Teacher: What size is this?
    Child: Smaller.
    Teacher: And this?
    Child: Bigger.

    Explicitly Teaching Math Concepts (2:20)

    Narrator: Through planned activities, children’s development of this skill can be strengthened.

    Teacher: It’s your job to figure out who has more. Which one is more - yellow or green?
    Child 1: One, two, three, four, five, six, seven.
    Child 2: I think I have more
    Child 1: One, two, three…

    Dr. Sudha Swaminathan: These comparisons of numbers and quantity leads them gradually to arithmetic, to looking at what’s more, what comes after, realizing that one more in a number sequence means one more in a quantity.

    Parent: Wait, how many do we have hanging on there so far?
    Child: Two. Now we’re going to have three.

    Dr. Sudha Swaminathan: And those basic, foundational skills are built when they start to compare groups.
