Activity 1: Fraction problem warm-up
Read (but don't solve) the 3 story problems below.*
Could each problem be used to illustrate 1 ¾ ÷ ½ ? Vote either YES, NO, or Not sure for each problem.
* These problems are based on released item #7 of the Mathematical Knowledge for Teaching (MKT) Measure, developed by the University of Michigan's Learning Mathematics for Teaching project. See www.sitemaker.umich.edu/lmt for more information.
