First, we read the statements out and found out that half of the cubes were red, a quarter were yellow and there is the same number of blue cubes as green cubes. Secondly, Oliver said that, on the picture, there are 4 cubes across and 2 down. Then, Daniel said that one of the lines along was: green, red, yellow. After that, we discovered that inside the green, red, yellow sequence was the green, red combination so we didn't need to do that card.
Then Daniel found on one of his cards was a corner piece with a red block and a yellow and blue block either side so we added that in. Then we found there was one piece left, the yellow, red, blue combination and all of the things were somewhere in our rectangle.
This is what it looked like in a drawing.
