- Counting: The child may have counted the number of garbage cans or the number of times the truck stopped to pick up garbage.
- Sorting: The child may have sorted the garbage cans by color or size.
- Measurement: The child may have estimated the size of the garbage cans or the amount of garbage in each can.
- Patterning: The child may have noticed a pattern in the way the garbage cans were lined up or the order in which the truck picked them up.
- Geometry: The child may have observed the shapes of the garbage cans or the truck and identified them as circles, rectangles, or squares.
Encourage continued development by providing the child with different types of vehicles to play with, such as cars, trains, or airplanes. Ask the child to sort them by color or size, count how many there are, or create patterns with them. You can also introduce measuring tools, such as rulers or measuring cups, and ask the child to estimate and measure the length or volume of the vehicles.
