So many maths ideas I can think of with the bag of chips. I’m doing area and volume and can work with both on my tonne bag of chips. I can also work out how many smaller bags I would need to hold my tonne of chips. I was also thinking I can see how many wheelbarrow loads it takes to move them to my back garden and I can work out the average weight per trip. I can also workout the length of my wheelbarrow trips and how long it takes for moving future bags of chips.
