Data Organization and Representation- Annenberg. When I hear the word statistics I think of polls, collecting data, analysts, and percentages. A general question that could be answered with statistics is how do you get to school? A random group could be sampled to gather the data. The data would be categorized into methods of transportation. The results would be interpreted according to number of bus riders compared to commuters. What would be a sample that is not representative? I used the formula of nu...

Describe Ms. Scrivner’s techniques for letting students explore the relationship between circumference and diameter. What other techniques could you use? I was impressed by the student who recognized circles as the rings in a circus and why we call the man conducting the circus a ringmaster. I didn’t know this until I was 37! So, wow, she made remarkable connections. They are allowed to discover and make connections that are meaningful that will result in deep learning. In seventh grade, we were give...

I saw the shape and thought crescent with a hole in it. Students’ descriptions of the shape:. Looks like the moon. Looks like the letter c. Looks like part of a jet ski. Looks like part of a circle because it has this (points to the inside curve) and it is half a circle. It has 2 points. Looks like a piece of melon (turns it on its side on the projector screen). I just remembered it, then confidently names the shape, it’s a crescent, it has two sides that are curved. It looks like a banana. Nets with 4 u...

July 18, 2013. I never know what to say when asked to “tell us about yourself! It turns out I can do math, and I don’t completely hate it. I would strive for my students to never experience the maddening frustration that I did. I would strive for girls to know they are good at math and have excellent problem solving skills. This is how I felt before my experience with a gifted math teacher……. I don’t want my students to struggle with math…. This entry was posted in Uncategorized. Enter your comment here.

The Probability of Winning a Goat! I saw this question in the discussion and exploration section and it made me quite curious….It is a great explanation of probability. Everything makes more sense when explained in a British accent. Key Ideas in Geometry. What are the key ideas of geometry that you want your students to work through during the school year? Can a triangle have more than one obtuse angle? Can a triangle or a quadrilateral have exactly two right angles? Can a quadrilateral have two obtuse a...

What are some important features of what’s happening in this classroom? What did you notice? What struck you about the students’ thinking? What struck you about the teachers’ moves? As you think about each of these, what’s the idea the students are working on? I noticed steps of the statistical problem-solving process being used. They formulated a question that could be addressed with data: how many pockets does each person have? Would be the data be different on picture day? It is helpful to know that t...

How tall is a typical first grader? Jason thinks that a first grader is about 53 inches because that is the most common height, or the average. Grady thinks that a typical first grader would be 51 or 52 inches because ordering the data, which is an even number, results in two numbers: 51 and 52. Samantha thinks a typical first grader would be about 2 inches shorter than herself, so about 51 or 52, because most of the first graders were the near her height of 53 . Samantha used the most common height (ave...

I struggled using the pentominoes in the last module as my spatial skills are somewhat undeveloped. I was encouraged to learn that our thinking can continue to improve with practice. I am thrilled to say I am seeing this in action with myself and it is very exciting! I was able to complete most of the puzzles (3×10, 5×5, etc) in the exercise. Furthermore, I was able to “see” the next piece that I would need and could imagine how it would look if it were rotated or reflected. Level 2: Informal Deduction.
