Talking about textures and what you notice helps your child to develop their natural sense of wonder and the language to describe what they see.
Talking together about what you have noticed and felt helps your child to ask questions. As they notice objects they can group them and compare the differences. When they talk about what they notice they are developing language to describe their thinking and observations.
When children begin to describe their thinking they have started to hypothesise. When they hypothesise they are beginning to connect what they see to past experiences and use this information to make decisions and reflect on why things have happened.
