Welcome a slightly different maths day..
Try to see the challenges today as a sort of game. A game with levels! The first problems you see are level one and as you scroll down the page, each new page of problems is a new level. How far can you get before you get really stuck? Feel free to ask an adult or email/message your teacher for help on any 'level' (question) you are on.
Remember, the first picture is level one!
