Factions.

LI: To use about halves, quarters, thirds, and some factions of shets. 

Today for Maths we learned about factions and factions is like halves, quarters and thirds like example: You cut the pizza into so that my friend can have a half each and also for example for the quarter you cut the pizza into four pieces so each four of my friends can have one quarter each.

And  the last one it thirds is like you divide your pizza into three pieces and then you and your friend can have one each.
