I've just been doing a maths sheet with DS and they had to divide some eggs between bowls.
I had this vivid flashback to a book I had as a child (late 80's/early 90's), with a baking bowl and eggs - I seem to remember them being quite big. The eggs were loose, and you got to put them inside the bowl. I've no idea what the storyline was, but presume it was about baking a cake...?
Can anyone help? I'd love to find it!
