Nrich 5 Step Challenge
By Oscar and Evie
To find a solution to the 5 step challenge our first step was to draw a diagram to see the number of cubes. We then worked out how many cubes would be needed for a staircase with 2, 3 and 4 stairs using the same type of diagram.
Next we put our data (our findings) into a bar chart to try and find a pattern between the number of cubes and steps. After seeing our data this way we saw the pattern and difference. We found that for the number of steps there were, if you squared the number of steps you got the number of cubes you would to use. Consequently, the algebraic formula would be n². This made us realise how much could be done with algebra and how useful it is.
