WHAT DO YOU NOTICE?

There is not enough chips for the person There is heaps of blue and not many cheese ones. There were more cheese ones There was one big bag of 10 packets There was a lady opening the bag The person seemed to be confused He opened the packet and I thought he thought there would be more packets than he saw. There was only two yellow chip packets. There wasn’t many chips. There was a person opening a bag of chips. There was 11 bags of chips - not an even number. They had the same amount of different coloured chips. There was an even amount all together. There were two different kinds. It was only half full There wasn’t as much green as yellow. There were too many chips to eat. The lady was disappointed. There was three different kinds of chips. There was only two blue packets and way more yellow ones. The bag wasn’t completely full of chips. The lady opened the bag and thought she had heaps of of her favourite ones but she had only some. There were more yellow than blue. There was more green than yellow.

WHAT DO YOU WONDER?

Why she made a gesture with her hands. Was she angry? What brand of chips they were? Why there weren’t many chips. What a fraction problem could be? Why the bag was yellow but not all chips were yellow? Why she didn’t get the same colour of chips? I wonder if she ate all of the chips? I wonder what would happen if they were sorted into groups of colours. If the bag was yellow and but not all of the chips were yellow, what fraction of the chips were yellow.
