What changed between then and now?

Two pictures can show what changed and what stayed the same. A fair comparison follows the same kind of thing from one picture to the other.

H05 visual explanationOriginal fictional then-and-now park illustrations, not historical photographs. Then: one tree, one bench, two flowers. Now: one tree, 1 benches, 4 flowers.

The flower count changes from two to four. Each drawing still has one tree and one bench.

These pretend park drawings both show one tree and one bench. The THEN drawing has two flowers. The NOW drawing has four. The number of flowers changed, but the tree and bench counts stayed the same.

The drawings show this difference without telling us why it happened. A change we can see is not yet an explanation of its cause. These are made-up pictures, not old photographs.

About this explanation

Starting knowledge: Match familiar objects across drawings and count up to four with adult support.
