Description

30 Cards displaying small, medium and large images of everyday items.

One of the most important sensitive periods for a child is between the ages of two and four, when s/he needs order in the environment.  During this stage, children instinctively want to sort things, to bring them into order.  They begin to solve problems, i.e. matching colours, learning to count, etc.  Visual discrimination, the next step, helps your child see differences in the size of objects that are the same or similar.  This activity also introduces vocabulary.  By understanding the difference between small, medium and large, initially with concrete material, e.g. beads or blocks and then moving onto images, children begin to (subconsciously) understand how and why size is important.
