This is my math notebook. This page is where I had to find a missing angle. It is where you know some angles of a shape, but not others and you need to figure out what the missing angles are. I am proud of this because I worked hard on this missing angle assignment, and I think that since I worked really hard on it, it turned out really good.
This is my Venn Diagram. In Math, we made Venn Diagrams. We used shapes, and we put them each into a category. I feel that this is something I am still working on, because I think that I could have put in more shapes.
In math, we each made a tessellation
. A tessellation is a design, that is all shapes, and all of the shapes are attached. The way to attach all of the shapes, is you have to measure all of the angles that are touching, and it needs to add up to 360 degrees. We made our tessellations using a tool called geometers sketchpad. I am proud of this, because this was a time that I feel that I showed growth in geometry.
Here are some hints to what number I am thinking of. Try to guess the number.
1. I am a factor of 700
2. I can make a rectangle 2 tiles wide
3. 70 is one of my factors
4. I am less than 200
This week in math, we have been thinking about how many people lived in the past 100,000 years. We were asked to try and make a graph that explains how the world’s human population has grown and shrank in the past 100,000 years. As you can see, my graph is pretty steady until the end where it goes totally up. Since my graph looks pretty much straight, that means that there hasn’t been too much change in the human population. At the end, where my graph went completely up, that means that the human population went WAY up. I had a lot of editing to do on my graph (the graph that you see). At first, I slowly started going up, but then, I was told that 8,000 years ago, there were only a few million people living on earth. The human population grew so much, because now, there are almost 8,000,000,000 people on earth and it has only been 8,000 years. It is so interesting that the human population grew so much in the past 8,000 years.
Today in math, we were making graphs based on three different problems. All of the problems were about different ways that people walked 20 meters. We got to choose which problem to a graph on. After we made our graphs, we mix and matched them and we were each given a graph that was not ours. Then, we had to put the graphs that we were given, up on the board, based on what problem we thought that graph was about. The way that we sorted out the graphs was that we saw the shape and the shape of the graph effected the meaning of the graph and what running story to put the graph in. If you look really closely at the picture, you can see that if two graphs are in the same category, they probably look pretty similar. When I looked at the board, I noticed a couple of things. I noticed that all of the problems that we were given to graph about were very similar, therefor, not a lot of the graphs were put in the wrong place. For some of the graphs, when people were putting them up on the board, a lot of people did not notice that the person stopped a little bit, so they placed them not knowing that the person stopped for a few seconds. I could say so much more, but then this post would take hours to read. I hope you all enjoyed this problem just as much as I did.
