With problem solving, always start and write down what your given. Here for example: 1/2 number of 4th graders as 5th graders 5 fewer 6th graders than 5th graders There's 9, 6th graders, how many 4th graders? Start off by using what you got and know. I'll put the grades in after the number like (6th) for 6th graders. 9 (6th) + 5 = 14 (5th) There's 5 more 5th graders than 6th graders 14 (5th) divided by 2 = 7 (4th) There's half as many 4th graders as 5th graders, so we divide it by 2. So there are 7 students in the 4th grade.
