This article was about the value of the guess and check method. It explained how this method could be used when doing word problems at the middle school level. The author explains that teachers need to be using this method because it helps deepen students understanding of quantitative relationships and help increase the students problem solving skills. The guess and check method help students to break down each word problem and put it into everyday language rather than just reading the math problem. Students use the table to help them organize the different parts of a problem. The guess and check methods helps students to use reason when finding the answer to the problem that was given to them. When students become familiar with this strategy they can adapt it and have their own way of using for different problems.
I thought that this was an interesting article to read. The guess and check method seems very useful when teaching students about problem solving. There were many examples of charts and tables that students used when organizing their guess and check system. This method is a way for students to understand what the math problem is saying because they are breaking it down and learning from an answer if they guessed it wrong. They have to look at their answers and reason them of why it is the right or wrong answer.

This article was about using technology when teaching students about polygons. There are many different kinds of polygons and a lot of students do not realize that shapes likes squares and triangles can be found in the different types of polygons. The website has a lot of different features that can help students to identify polygons better. The paintbucket tool also helps the students with polygons beause they can draw different conclusion from the different colored polygons. The article also states that students are engaging themselves with polygons by using the technology. They can interact with the polygons by having them on the computer and play around with the polygons to see the different kinds that they can create.
I thought this article was very interesting because I have never really thought that much about polygons. By doing this activity on a computer the students are able to make different kinds of polygons. The computer gives them the ability to try to come up with different solutions. Some of the shapes that are in the article are not polygons and it allows the students to see why they are not. I think that this is a good activity because the students are engaged with the polygons they are not just learning what a polygon is out of a book. Another interesting thing is that students can take different shapes like squares and put them in a polygon and see how many squares fit in each polygon or triangles. I would use this activity in my classroom because I feel like the students would get more out of this lesson rather than from me teaching them on the board. Overall, I thought that this was really interesting and would use it in my classroom.
