              framing Word Problems

              We have learnt how to solve word problems based on the four basic operations, that
              is, addition, subtraction, multiplication and division. To identify which operation to be

              used,  we must  be  aware of the  use  of keywords,  such  as  total,  sum,  difference,  in
              all, remaining, left, together, contribution, collection, etc. in the given problem. Now,
              it is the time to frame word problems relating to any real-life situation.

              The teacher writes four number sentences on the blackboard. She tells the class to
              frame any beautiful story for each of the given facts.

              Let us see what word problems the students have framed.
