The laws Complementation 1 and 2, together with the monotone laws, suffice for this purpose and can therefore be taken as one possible complete set of laws or axiomatization of Boolean algebra.
The dot plot represents the number of problems each student attempted on Linear Practice 1, on which students tried to solve as many one-step and two-step linear equations as they could in 10 minutes.
This is the first time students are seeing a dot plot in my class, but I post it as is, knowing that this is a very intuitive data representation.
As posted on today's agendathe opener is to "Copy this 9 dot box problem algebra into your notes, then find the mean, median and mode. I make the observation that I see both as I circulate, and I say that either option is great.
After a few minutes, I ask, "When you look at this dot plot, which of the following is easiest to find: Many of my students want to use the method of crossing off number on each end of the data set in order to find the middle number.
I'll work hard today and over the course of the next week to undo this training, by saying that it's really important to think of the median as the number that splits the list in half.
The best first step for finding the median is to count how many values are in the data set, then divide this number in half, and count that many data points. Each class has a different number of data points, so this conversation is slightly different each time.
U2 L4 Linear Practice Data. It consists of five problems, the first four of which are related to Linear Practice 1. The first problem is to create a box plot of the "problems attempted" data set that opens today's class. In some of my classes, students are ready to run with this task.
In others, they need some help. I draw the number line, and write the data above and around it, showing how much of the data goes where. Moving from dot plots - which are a very explicit form of data representation - to box plots, whose use can be very mysterious, is an exercise in reasoning abstractly and quantitatively Mathematical Practice 2.
The notes I give to students on the board are designed to help students in this challenge, by allowing them to see half of the data on one side of the median, and half on the other.
One of the niftiest tricks here is to trace the number line from the initial dot plot slide, then to remove the data from the whiteboard and make the box plot. This really helps kids to see that one-quarter of the data is in each quartile on the box plot.
Up to now, we've been analyzing the number of problems attempted by each student. The next two problems on the problem set ask students to create a dot plot 2 and a box plot 3 of set of numbers of correct answers on Linear Practice 1. On today's presentation slides, there's a comma-separated list of data for each class.
My planning move here is a time-saver: I can make copies of the same problem set for all students, and then allow each class to work with their own data, projected at the front of the room, as they work on these problems.
Problem 4 shows a dot plot of the data for all of my algebra classes.of algebra. Students will engage in problem solving, graphing, quizzes and projects. Students Type in the number you guess and then click on the red dot. Adjust your guess based on the feedback.
