Mathematical Similarity Summary
Figures are mathematically similar when…
- corresponding angles are congruent
- there is a scale factor (SF) going both ways
- cross products are equivalent
- area changes by SF squared
- perimeter changes by SF
Any two rectangles are similar. This statement is false, all similar figures follow the reasons listed above.
Any two equilateral triangles ar similar. This statement is true because corresponding angles are congruent.
My Soundtrap Song
This is my song.
Soundtrap is very useful and fun. I made this song by making up melodies, and then adding a drum part. I also had other people play on this piece, and I uploaded some things from noteflight to do this. I think that Soundtrap is a very useful tool when one is making a song.
My Current Math Status
This is my Xtramath score report. Xtramath is a website that is designed to help kids practice multiplication, and we have to use it every night. I think that I am making progress, given that although I do not usually get to see my current score, I am having an easier time remembering answers right away in class. I think that my effort is increasing. I probably am putting more effort in than I was before, because my score is going up. I think that Xtramath is a great website for kids who need help remembering their multiplication facts.
This is one of the little pop quizzes that Margaret has us do in the beginning of class. At the moment I am not doing very well, but I am determined to do better, since I REALLY do not like getting a bad score, let alone not learning this! I am going to improve by practicing Xtramath, and by paying as much attention as possible in class. I know that I need to improve my work, and I will try very hard to do so. After trying and succeeding, the best thing is trying and failing, so I will try.
This is a page on my test that I am proud of. I am proud of this page because I got all the answers right, and it seems that I did it in an acceptable way, because I got no comments from Margaret! I think that this was a very cool test, because it was a take-home test. Those are easier than regular tests, because you are doing it in a less stressful environment! Thank you for your time.
My number puzzle
My number is lower than 20. My number is a factor of 30.
My number can make only a one tile wide rectangle. My number is odd.
What is my number?
Math graphing observations
In this picture, you will notice many different graphs. Now, as good as they may seem, none are perfectly accurate. Some have stops that do not fit the story. Some have sprinting instead of speed-walking. All have their own different faults. I will not specify people’s graphs, but there are many worth commenting on. The graph on the top right of section B, for example. At the end, it barely slowed. In the beginning, it sprinted instead of walking. The bottom left in B, has some problems too. The beginning makes it look like it starts at 5 meters. Well, when you don’t inspect it closely, that is. The top right on C goes even further in meters, than in seconds. The top left on B stops at three fourths of the way to the end. It was only supposed to go halfway. I will not blame anyone because it is not really their fault. Perfect graphing is not an overnight skill.All the graphs could be better. But as I said, you can’t blame them. By the way, you may have to scroll over to see the whole picture.
