Crack The Safe – Rounding, Estimation and Bounds
Free
Two “Crack The Safe” activities on rounding, estimation and bounds; the first one is simple decimal places and significant figures and the second involves bounds. These contain six questions but ten possible answers 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.
