Three “Crack The Safe” activities on expressions: expanding and factorising, including quadratics and expanding three brackets. These contain six questions (four on the three brackets) but three possible answers for each question meaning that students can self-check their answers (are they in the list of possible answers?) whilst the teacher can help those who require it. I use these as starters and plenaries but that is obviously up to you.

A humongous pack of crack the code resources for expanding and factorising. I love these! Thank you for sharing.
