A moment between adult and toddler using balls and tubes is an opportunity to explore important "precursor" concepts of math that begin very early. In this case, we see how comparison is something that comes along often in everyday life and in play. This early exploration with comparison builds the foundations of thinking about measurement as young children move on to preschool and beyond.

Why is this important?
The teacher’s language labels the implicit comparison between various sizes of tubes. The ball won’t fit in the narrower tube, but it goes through the bigger–the wider–one. She shares her attention and responds to the interests of the toddler.

Comparison: Comparison is noticing sameness and difference.
Comparison depends on recognizing attributes.
Recognizing attributes makes it possible to notice sameness and difference.
Noticing sameness and difference allows for matching, sorting, ordering and problem-solving.
