Hi, I have planned an exciting week around the theme of wizards and scientists because last week all the children wanted to do was make potions. I have got lots and lots of great ideas and am really looking forward to it! I've got activities to cover lots of areas but unfortunately I have an observation on Tuesday and have to do a calculating activity. I am struggling to think of anything to do with calculating based around potions. Each day I am going to write the children a letter from a character who is in need of the wizards to make a potion for something. I thought perhaps I could write a letter from a fairy/elf (perhaps even use photoshop to show the fairy in our outside area) with a recipe for some kind of potion that she/he needs making except the children have to double the ingredients (higher ability) or use one more/two more (lower ability). Does this sound too complicated? I think I'm making this confusing for myself just because I'm being observed. Been thinking about this all day! Any help or advice would be much appreciated. Sure I am missing something really simple!
