Fractions always seem to trip up students. Things get murky when talking about different size “wholes” or when switching from thinking about the fractions of one whole to fractions of a set. The only way to combat fraction-mayhem is to provide students with a LOT of opportunities to experience fractions with tangible objects. Pattern blocks are a popular fraction manipulative, but I like LEGO even more. (Pattern blocks can only be broken down into sixths when using the hexagon as one-whole. LEGO blocks have many more possibilities!)
