This assignment made me realize how difficult evaluating math problems can be, especially when we are taking into account more than just a simple right or wrong answer. It is important to analyze the student work so that we can understand how they reached the solution whether it is correct or incorrect. For example, some students have grasped some skills necessary to solve a problem but need more assistance in another aspect of the problem. Also, we want students to get away from putting an answer and not explaining their reasoning because the further they may dive into math curriculum, the more important it becomes to understand why answers are true and how certain theories or algorithms work.
My group was in charge of assessing the 8th grade level problem entitled "Marcy's Dots". Our group worked well together to decide which student work constituted each level of the rubric which was an important step so that we were all on the same page when deciding a score. When sharing our scores with the class, it seemed that there was agreement with our decisions and that our implications for the teacher made sense as well. I enjoyed hearing other ideas from the class and discussing each level of student work.
When looking at other groups' NAEP problems, it seemed that some were much more difficult to grade than our group because of a complicated or not specific rubric. This definitely sparked discussion among the class as to which grades we thought that each piece of work deserved. It was difficult to reach a conclusion at times because people can interpret what the students have shown and what that implies that they know differently. Overall, I learned a lot about assessment during this project as well as the importance to instruct students at a young age to completely explain and justify their work with math problems.

Rich Activity Reflection
I think that too often math becomes a subject in which students repeatedly complete computational problems out of a textbook, take notes from the whiteboard, and then take an exam. Although there is a time and place for these sorts of exercises, there is a big need for teachers to incorporate activities that require their students to take the knowledge that they have been building and apply it to a task or problem. Allowing students to explore in mathematics and come up with ideas on their own is critical in developing their problem solving skills and it may also give them more confidence in this subject area.
The rich activity that my group decided would have worthwhile content as well as being enjoyable to middle school-aged students involved using ratios, proportions, and geometry to find the relationship between objects and their shadows. I was very disappointed that we were not able to complete the activity with the class due to bad weather, but I think that granting students the ability to go outside to complete a hands-on assignment is ideal. This type of activity also shows the students that what they are learning in the classroom relates directly to real life.

Video Analysis #2
The teacher's overall theme of connecting back to "pictures being worth a thousand words" is a very interesting concept. In mathematics, drawing pictures to accompany the answer will show how much of the information the students understand on a deep level and what are simply facts that they have memorized and can recite when needed. I like that the teacher gives examples of drawings and representations when the students come up with the idea that multiplication as repeated addition so that they know what she means by "math pictures".
During the discussion about multiplication, the idea of equal groups comes up. This is a key concept to multiplication and division so is important for the students to be familiar with the idea. In the teacher commentary, she explains that she kept trying to bring this notion back up during the discussion of division, since the students were struggling, but they were not connecting it back to grouping. The reason for this is probably because the students are not used to the mathematical language and therefore have a difficult time voicing their explanations of retrieving their solutions. So, even at a young age, students need to be introduced to and expected to use mathematical vocabulary to explain the reasoning behind their problem solving.
Since there is such a large amount of discussion and interaction with peers, it is critical that there is a very comfortable classroom environment in place so that all students feel that they can express their ideas safely. Being able to critique the work of others and taking corrections on your own work are crucial steps in finding a solution and group discussion. Rules should be put in place so that working together goes smoothly whether it is whole group, small group, or partner work. In the video, the class seems to have healthy conditions for collaboration, however when the student work shows that the small groups have a big impact on the students final answers. If they think that their peers have the correct answer, they may change theirs without being able to explain how the solution was reached. The teacher also had great control of the classroom and was able in incorporate fun attention-getters that keep the students engaged and attentive.
I thought that the teacher's mental math question was well chosen because it was not too difficult but was not a fact that most students would have memorized; they would have to choose a strategy to think about to get to the answer. Moving to a word problem was a very sensible next step in the lesson because it allows the students to apply the knowledge that they have been building upon throughout the lesson. Posing this question also lends itself to connecting back to the theme of drawing mathematical pictures. The teacher sets up the problem so that there are not specific instructions and therefore lets the students use their own exploration to come up with an answer. When looking at the student work it seems that some students knew how to get the right answer, but their pictures do not align with their answer, so we know that these students just know the facts of the problem and need to continue gaining a deeper understanding of the topic. Lastly, including student reflection can help the teacher to place where each student stands in grasping the concept and what next step needs to be taken in the overall unit.

Math Applets/App Review
Candy Factory Educational Game (Grades 6-8)
https://itunes.apple.com/us/app/candyfactory-educational-game/id446248045?mt=8This app allows middle school aged students to practice partitioning and iterating involving fractions. The main concept is that the player is expected to complete a candy bar order for the customer. However, they will need to split up and copy parts or the candy bar to reach the correct size. The game is timed and and accuracy is monitored, however there is the chance to adjust your answer, considering the tasks become quite difficult to complete correctly on the first try.
I think that app can be very beneficial to students, especially since fractions tend to be an area where extra practice and deepened understanding is vital. The tasks that are being asked force the students to look at fractions in a way that will help them when using improper fractions as well as multiplying and dividing fractions. The player receives immediate feedback when completing each challenge and is also given a summary of how they came to the correct answer which allows for reflection over the process of solving the problem.
Circle 0 (Grades 3-5)
http://nlvm.usu.edu/en/nav/frames_asid_122_g_2_t_1.html?open=instructions&from=grade_g_2.htmlThis applet involves solving a puzzle using properties of numbers and operations. The player is given seven circles that are overlapping, so there are three parts in each circle. A few numbers are filled into various parts of the circle which cannot be moved. Then there are the remaining number (no extras) off to the side in which the player uses to fill in the empty spots. Each circle (so three numbers) need to add up to zero using the numbers given (there are positive and negative numbers).
multiple
This task gets a student thinking about how numbers relate to one another. The challenge lies in the fact that there are only certain numbers available to complete the puzzle and the circles are interconnected so the placement of the numbers is important and causes the students to think ahead and use problem solving skills. Once one circle has reached zero it changes colors so that the player is aware of their progress and the puzzle lends itself to much adjusting and revising which is a good skill to embrace when completing math tasks.
Color Patterns (Grades K-2)
This applet gives the player practice with patterns by using color. A strand of colored dots appear on the screen, followed by multiple blank dots. There are all the possible colors including ones that are not in the pattern on the side of the screen. The player then clicks the empty circles and then the color that would continue the established pattern.
Allowing young students to work with patterns involving color prepares them for intricate patterns involving numbers, and eventually formulas and functions. The applet gives the player the ability to check their answer and make corrections if necessary which can activate their problem solving skills. Completing the pattern also stimulates the child's attention to detail in which students need to be proficient when succeeding in furthering their understanding of math concepts.
