Looking at patterns and how they grow is something we've done lots before. But this time in Year 4 we took particular time over something different: what exactly the first step should be.

Look at this pattern here, a pattern of "C" shapes:
We had a long discussion about that first single cube. Did it really belong in the sequence? Some thought yes, some no. We didn't really come to a definite conclusion, but the good thing was that we were able to explain our reasoning one way or the other.

For instance with this pattern of "H"s:
The two girls were more than happy to explain their thinking:

How about these other sequences? Do you think the first one is right?
