Reflection On Video 10 Marshmallows

The following video observation and reflection, I am writing about today is based on video ten, Marshmallows. In this video, Second-graders create and discuss a bar graph based on the number of marshmallows they estimate each person in their class would eat on a camping trip. After discussing their results, students determine how many bags of marshmallows to take. In the given description for the Marshmallows video, it states that the NCTM standards outline this activity for focusing on concepts of whole number operations, statistics and probability, reasoning, problem-solving. Looking at what I observed in the video and what is listed in south Carolinas state standards I think standard 2.MDA.9 and 2.MDA.10 are appropriate. Standard 2.MDA.9 …show more content…

The career-ready mathematical process standard number two states that students will be able to reason both contextually and abstractly. Process standard 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 the students to all have enough to roast on their class camping trip. The problem itself is a real world situation that will have consequences for the student’s themselves. If the estimate a low number of marshmallow bags to bring on the trip some of them will still be hungry, if the number they estimate is too high then they will most likely have to many left over 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 split up into groups to manipulate the marshmallow in their bags some student’s had remainders. When they discovered that everyone could not have and the equal amount they devised several solutions. One group of student’s suggested that anyone who wanted more than four marshmallows to get the remained, another group asked that the remaining marshmallows be cut in half and divided between everyone else in the group. The third mathematical process standard asks that students use critical thinking skills to justify mathematical reasoning and critiques the reasoning of others. Standard 3(a) states that students will construct and justify a solution to a problem. Toward the end of the video the children elected a spokesperson to present their answer and the children debated the amount of marshmallow bags they would need for their camping
