|Most students mentioned that 5/3 was an improper fraction, and I mentioned that improper makes it sound like there's something wrong with it. I emphasized that there's nothing wrong with it, it actually can make it easier to work with at times.|
|I liked that they said 2/10 is only one not in simplest form. I reminded students that that means it can't be reduced to an equivalent fraction. I love that a student noticed 2/5 is the only whose reciprocal can be written as a mixed number. Seeing them test their ideas before sharing them was great to see.|
Students took notes last week on identifying functions represented as tables and graphs. I introduced vertical line test last Friday. Since it was 2 day lesson, and I wanted students to practice more interpreting, we used the pre-Common Core Algebra 1 textbooks. I got the idea from Ms. Demailly because she had assigned HW out of it. By the way I'd be open to suggestions on how else to introduce and reinforce this concept.
For accelerated, we discussed these parabolas WODB (thanks Mary Bourassa and WODB.ca):
Introductory vocabulary revisited. Some new vocab with domain and range. I said domain was basically the input or x values. Range was the output or y values.
In each class I asked students to specifically describe why choices A, C, and D were not functions.
Students worked on questions 10 through 17.
|I liked that students noticed the top left was the only one with a line of symmetry on the y-axis and a positive and negative x intercept. One student noticed bottom right stops because it has no arrows. His peer built off that idea and said that because of that it will never have a y-intercept. The one thought I added to "only one with its vertex on the x axis" was it was the only one with an odd number of x-intercepts. I also like how when a student mentioned bottom left was only one that opens up, another student added it therefore it is the only one that has a minimum.|
They practiced reading number line graphs, solving 2 step linear inequalities.
|overall, great ending to the week.|
