DEVELOPMENTAL INDICATORS

Infants (Birth to 12 months):

  • Examine objects of different sizes by exploring (touch, pick up, and move objects).

Younger Toddlers (8 to 21 months):

  • Participate in activities that compare the size and weight of objects.
  • Engage in beginning explorations with temperature (quickly touching cold and warm items).

Older Toddlers (18 to 36 months)

  • Use size and amount words to label and compare objects, people, and collections (big truck, a lot of crackers, little baby)
  • Engage in continued explorations with temperature.

Younger Preschoolers (36 to 48 months)

  • Use descriptive language for size, length, or weight (short, tall, long, heavy, big).
  • Compare the size or weight of two objects and identify which one is longer/taller/heavier than the other (“That rock is heavier than this one. I can lift it.” “The snake is longer than the worm”).
  • Use simple measurement tools with guidance and support to informally measure objects (a ruler, measuring cup, scale).
  • Describe the weather as hot or cold (Engage in explorations with temperature).
  • Recognize routines with time passing throughout the day (identifying circle time, snack time, outside play, etc.).

Older Preschoolers (48 to 60+ months)

  • Use descriptive language for size, length, or weight (short, tall, long, heavy, big).
  • Directly compare more than two objects by size, length, or weight (“That rock is heavier than these other; I can’t lift it.” Look at three strings that are different lengths and select the longest string).
  • Put a few objects in order by size, length, or weight (arrange a group of 3 blocks in order from the shortest to the longest).
  • Use simple measurement tools with guidance and support to informally measure objects (a ruler, measuring cup, scale).
  • Describe the weather as hot or cold (Continue to engage in explorations with temperature).
  • Recognize routines with time passing throughout the day (identifying circle time, snack time, outside play, etc.).
