Good morning all, today brings another teaser, which is not meant to be taken too seriously. It may cause some controversy, as depending on how you interpret it, there are two possible answers. Good luck and be gentle with me!
Sparkling, these types of questions are a combination of algebra and problem solving.
I would hope wouldn't fail in my class, as I would have taught you lots of strategies and demonstrated lots of examples, before expecting you to solve it. Initially, I would pair children up to talk about how to solve it and then share with the rest of the class, so no pressure! ☺️
