Junior students often get x^2 mixed up with 2x etc so this is an attempt to give them an opportunity to sort them out for themselves. The questions are mostly of a basic level but they do include 1 = x/x etc.
Students partly use the process of elimination and partly use educated guesses but mainly seeing the whole smorgasbord in front of them at once is very helpful because it means that they can ask questions and get them answered straight away either by peers or by you, the teacher. Answers are included in two forms.
Ideally they should cut out the tiles and manipulate them although some prefer to highlight. Highlighting is not recommended as it becomes difficult if they change their minds.
Suggestion: give them a similar mixture of problems straight after this exercise.
