How many cards? How many card triangles?

We watched the video to help us solve the problem. 

We documented our thinking and strategies in our Maths Journals.

Together, we worked out how many cards were used to create the ‘Card House’.

Then, we counted the number of triangles used to create the ‘Card House’.

We realised that counting in 3’s was a great strategy to use!!
