Heather in Neverland Posted September 7, 2012 Share Posted September 7, 2012 WHY should students know how to do Front End Estimation? It is in our Singapore Math curriculum and it comes after we have already taught how to round numbers. I know WHAT it is. I just can't figure out WHY they would need to know it. It seems to be just confusing them. I need a pedagogical reason for teaching it because my math teachers and my students are frustrated. I had never even heard of it until this week! For those of you following along: typical rounding of numbers: 576 + 324 600 + 300 In front end estimation, you take the first digit and put a zero for everything else: 576 + 324 500 + 300 Yes I know it is just another (less accurate) way of estimating but I need to know if there is some other skill they will learn later that builds on this? It just seems sort of pointless. . Quote Link to comment Share on other sites More sharing options...
