This is the one I used in my lesson. Third graders are asked to use different kinds of estimation to solve problems. This webquest asks students to use rounding, compatible numbers, front-end estimation, and cluster estimation to calculate the items and cost of a large party (hosted by Shrek!). I was happy to see that the links are all working properly and the content was appropriate for third graders to use. I supplemented it with a worksheet, so students can show me (the teacher) their work.
