]]>The post Generative AI and Writing appeared first on X•Y Charts: Multiplication for Math.
]]>Our systems analysis approach to restructuring the K-12 writing class promises to make student writing better than ever. Thanks to generative AI tools, teachers can be liberated from busy work, so that they can concentrate on creating helpful and frequent writing assignments. We will discuss the threats and promises of generative AI, what tools like ChatGPT, Bard, Bing, etc., can do now, and we will explore ideas for getting the minds and bodies of our students back ‘into the action.'”

]]>Educational fads are fun to follow, but they mislead. Emotional and mathematical intelligence are necessary ingredients for a balanced life. We get that. Textbook publishers and educational bureaucrats prefer the acronyms of fads. These encourage new textbook updates and special government funding.
A How Are You Feeling Today? and an XY Chart on the wall addresses both areas visually. No fads needed.

]]>Your attitude as a parent can make a big difference in your child’s success in school. During my years of teaching algebra, I often met students who were proud to admit that they couldn’t do math or didn’t like math. They would say that they picked this up at home. The activities suggested here are not difficult and can be fun for both parent and child. What a difference this can make in your child’s future math classes!

]]>How can you divide if you can’t multiply? How factor? How find common denominators or common factors? Algebra is very painful for those students who don’t know the facts. They are doomed to rely on technology.
So for “drill and kill” I propose:
And besides, the difficulty of the task is overrated. Check this out.

This figure called a parabola tells all. Other alternatives such as a list of resulting (x,y) number pairs
(3,9), (4,16), (-2,4), (5,25), (-10,100), (6,36) or the popular xy table:
X | Y |
-5 | 25 |
10 | 100 |
-3 | 9 |
11 | 121 |
-6 | 36 |
0 | 0 |
1 | 1 |
-4 | 16 |
7 | 49 |
4 | 16 |
15 | 225 |
We can later explore how to use the graph, but for now recognize that if a range of x values starting with negative numbers and proceeding to positive numbers is multiplied by itself, those pairs of x’s and y’s when plotted as points will produce a figure that goes down and back up in symmetrical fashion. That’s easier to see with the graph.
Here is a great online graphing calculator if you’d like to experiment. Enter y = x^2 in the input field to see this parabola.
