Simply invite a young child / young children to discuss the picture. What do you see / notice ? What questions do you have / wonder?
Young children may notice similarities and differences (e.g. colors and shades of colors, material, size)… They may count items, by ones or groups (e.g. one box, a group of two carrots, or five carrots on a blue plate)… They may wonder (e.g. who is getting ready to have lunch, why the sets are different) and connect with what they do at school, in the home or beyond.
No right or wrong answer, just an opportunity for young children to engage in discussion around early mathematics.
