Headline Stories are deliberately open-ended to encourage various levels of responses. For this Headline Story, you might want to prompt creative and logical thinking with a question such as “If you use 7 green boxes to make a tower, can you make a red tower the same height?”

In Kim’s set of building blocks, there are small green boxes and large red boxes. Each red box is as tall as two green boxes.

- If you build a red tower and a green tower of the same height, you will use more green boxes.
- If you make a red tower that is 3 boxes, a green tower of the same height would be 6 boxes.
- For a green tower and a red tower to be the same height, you have to use an even number of green boxes.
