Color Steps Building Set

The Color Steps Building Set makes a tabletop skyline out of rectangular blocks in matching height pairs. The color sequence begins with short cream forms, rises through peach, mustard, and sage, and ends with the tallest sky-blue pair. The simple shapes make changes in height easy to see when the blocks stand next to one another.

Place the pairs in ascending order to make a staircase, then turn the whole arrangement around so it slopes the other way. Split the matching blocks into two rows and compare them side by side. For a simple challenge, leave one space open in the second row and use the first row to work out which block belongs there.

You can also put the tallest pair in the middle and let the shorter pieces step down on either side. That small change makes the same colors look like a different skyline, with a center peak instead of one steady climb.
