In our class, we have been working on patterning in math workshop. We created a pattern using our names where each letter had its own color. The name unit was then represented in pictorial form.
We made repeating patterns using our names as the unit (part that repeats).
The repeating patterns created some interesting designs on our grids.

The next step was to see how the unit could be changed to create a growing pattern. A growing pattern changes in a predictable way in each iteration (or step).

We made growing patterns using unifix cubes.

The next day we created a new growing pattern with unifix cubes and represented it pictorially with each iteration in a separate line.

Can you explain how the above pattern grows each time?
