Career Ready Mathematics Process Standard number two states that students will be able to reason both contextually and abstractly. Standard Process 2(a) asks students to make sense of quantities and their relationships in mathematical and real-world situations. The quantity discussed in this video is the amount of marshmallows needed for all students to have enough to roast on the class camping trip. The problem itself is a real world situation that will have consequences for the student themselves. If they estimate a low number of bags of marshmallows to take on the trip, some of them will still be hungry; if the estimated number is too high, they will most likely have too many leftovers to eat. Standard 2(d) states that the student will be able to evaluate the success of an approach to solving a problem and refine it if necessary. When the children broke into groups to manipulate the marshmallows in their bags, some students had leftovers. When they discovered that not everyone could have the same amount, they came up with different solutions. One group of students suggested that anyone who wanted more than four marshmallows take the remaining one, another group asked that the remaining marshmallows be cut in half and divided among everyone else in the group. The third mathematical process standard requires students to use critical thinking skills to justify mathematical reasoning and criticize the reasoning of others. Standard 3(a) states that students will construct and justify a solution to a problem. Towards the end of the video the children elected a spokesperson to present their response and the children discussed how many bags of marshmallows they would need for camping
