Rosa's doing her bit for National Baking Week and, as well as bringing in a very lovely fruit pie to share, has also brought us this week's puzzle. Hooray!
As you can see it's all about the squares!
The question is how many SQUARES are in the puzzle? Not rectangles, they don't count, just SQUARES! Let us know by replying to THIS blog with the correct answer, and if you get it right, you'll get a very special mention next week.
