Which strategies can be used to solve this problem? a county fair plans to have 24 pigs in its pig exhibit area. eight pigs can fit in a large circular pen. the rest of the pigs will be put into square pens that can each fit 2 pigs. what is the fewest number of square pens that will be needed so each pig is in a pen? . a. work backward. find the number of square pens by dividing 24 by 2. then what is left over goes into the circular pen. b. use logical reasoning. subtract 2 pigs 7 times. the number of pigs left will be the number of pigs in the square pens. c. translate into an equation. (24 – 8) ÷ 2 = p d. model the problem. use 24 objects to represent the pigs. move 8 objects into one group. then put the remaining objects into groups of 2. then count the groups of 2 to find the number of square pens.
