Robbie identifies and describes objects that are big and small, considering different attributes of the objects.

Bella compares two rods to say which is bigger. She justifies her answer by lining them up along a common baseline.

Bella identifies the Three Bears in an illustration by size. She then represents the bears using rods of different lengths.

When Alice first tries to measure a stick with cubes, she leaves spaces between the cubes. After being instructed to connect the cubes, she measures again. Her measurement is not exact, but it is close.

Having already measured an orange stick as 6 cubes long, Lucy estimates the length of a longer stick as 10 cubes long.

Alice measures a long stick with cubes and compares its length to that of a previously measured stick.

Sebastian is scaffolded as he measures with an inch ruler. Then he measures on his own, noting if lengths are exact or a little longer or shorter than lengths shown on the ruler.

Diane estimates that more centimeters than inches are needed to measure the same length because centimeters are closer together on the ruler (smaller units).
