2 Visualizing the Language of Math ~ Asilomar 2010Re-composing helpsunderstandingReading information in one form(such as words and sentences)and summarizing it in another form(such as a diagram or table)requires students to think about themeaning before they can re-compose the information. Re-composing is a key strategy inaiding Story Problems LessonStudents use Language , symbols, and pictures in the problem -solving Needed:large group: chart paper; markers; Story problem written at top of chart papersmall groups: prepared Story problems; white construction paper; colored markersindividual work: prepared Story problems, unlined white paper, crayons or markersWhole Class Introductory Activity:Post a blank sheet of chart paper or butcher paper, on whichyou ve written or glued a Story problem , large enough so allstudents can read it.

3 Choose volunteer students to do thefollowing:Read the problem key words in the the Story using simple an equation that solves the a sentence that answers the check to see that everything or Small Group Work:Small groups follow the same procedure as used in the wholegroup introduction. Prepared Story problems printed in large font are distributed to thegroups. Use challenging Story problems. If each group has a different problem but theproblems are related in some way, the sharing out time offers more opportunity forreinforcing concepts and strategies. Student groups share their strategies with the class,explaining why they drew what they drew, and and the reason they chose students to ask questions about strategies and follow up with questionssuch as the following for each group:Does everything seem to work in this strategy?

4 Could it have been solved a different way?Individual Work:Students go on to solve individual Story problems on their ownusing the same procedures. Story problems can come from the book or from a bank ofteacher-prepared Story problems. If desired, sorted into boxes by type ( ,addition/subtraction; multiplication/division; fractions; two-step problems, etc.)Ren e Goularte~ Story Problems: Visualizing the Language of Math ~ Asilomar 2010 Story problem from a 2ndgrade whole class Story Problems SamplesFor an expanded lesson plan, go to ~ in the search keyword box,type Giant Story Problems.

This does not teach studentshow to solve problems. What if we gave lessinformation, or too muchinformation, so that studentswould need to make somedecisions as to what theproblem is, what informationthey need, and whatstrategies they might use?

7 Ren e Goularte~ Story Problems: Visualizing the Language of Math ~ Asilomar 2010 Some Food For Thought About problem -SolvingOne Friday, Arnold Zwicky s granddaughter brought home this word problem :Mother cat had 6 kittens. 5 kittens went tonew owners. How many were left?Her answer, duly checked off by the teacher, was 2 cats were left. Is this word problem asking about cats or kittens? Are two answers acceptable?What if this were on a standardized test?_____Read more at Arnold Zwicky's typical Story problem might look like this:There are 5,280 feet in a mile. If you live half a mile fromschool, how many feet from the school is your house?Does this problem even make any sense? Does anybody care how many feet they livefrom school? Is there any problem -solving involved?Consider these alternatives: You live half a mile from school.
