- Counting the number of friends playing in the pool
- Comparing the number of toys each friend had in the pool
- Measuring the depth of the water using hands or feet
- Estimating the amount of water needed to fill the pool
- Identifying shapes of pool toys and describing them
Parents can encourage continued development by introducing measurement tools such as a measuring cup or ruler to help the child understand the concept of volume and length. They can also ask the child to sort the pool toys by color or shape to enhance their classification skills.
