Document Summary

Name_________________________________________ instructor__________________________________: using the number lines below, label the tick marks in two different ways. The tick marks should be labeled logically in terms of place value and sign: a. Round 3. 466 to the nearest tenth. b. label the number line below to justify the number that you rounded 3. 466 to. Be sure that your number line justifies your rounding: consider the following diagram: One student claims that this diagram represents the fraction 6/8 , while another student says that the diagram represents the fraction 6/4. Explain without using common denominators or cross-multiplication or decimals: john solves 114 97 in the following manner. So the answer is 3 + 14 =17: describe the student"s strategy in words and explain briefly why the strategy makes sense, rewrite the student"s work, using the same ideas, but using the = sign correctly, a. Show how to use a number line to calculate 1 + ( 2). b.
