When you and your child explore which fruit and vegetables have seeds you will be using prediction and comparative language. When you compare how they grow or talk about the amount of seeds inside, you are using number and size to make decisions. Number, size and quantity are forms of measurement.
Researching when different plants get planted and when they fruit helps your child to develop planning and sequencing skills. They will be using time and temperature to help make decisions about when something should happen.
Your child will be developing rich oral language to describe what they are doing, to compare one plant to another and to explain the growing cycle of the plant.
