C. Estimation 1. Judge without counting whether a set Everyday Mathematics, Unit 1 and of objects has less than, more than, or the ongoing activities throughout the same number of objects as a reference year set. Teaching Student-Centered Mathematics, Grades 3-5, Lovin and Van DeWalle 2. Construct and use a variety of Everyday Mathematics Units 2, 7, estimation strategies (e.g., rounding and 9 mental math) for estimating both quantities and the result of computations. *Estimating Costs Everyday Mathematics, Lesson 7.7 3. Recognize when an estimate is Everyday Mathematics, Unit 7 appropriate, and understand the Exemplars, Best of Math I and II usefulness of an estimate as distinct from CD an exact answer. 4. Use estimation to determine whether Everyday Mathematics, Unit 2, 7, 9 the result of a computation (either by Teacher supplement calculator or by hand) is reasonable. Exemplars, Best of Math I and II CD *Estimate answers to multi-digit addition Everyday Mathematics, Unit 2 and subtraction problems
