Project 4

Presentation Script
Hi, my name is Jacqueline Huff and the project I choose was the algebra project. I wanted to look at best fit line for a set of data and observe how the line changes when the data changes. I found random data points by using the software and entered them into a spread sheet. Based on SMP #5, I created two input boxes for the slope and the y-intercept of the graph so that students can try to guess what the line of best fit is. There are also two buttons that hide and show the line of best fit and the quadratic regression of the data so that students can check their work after they guessed. This is different from paper and pencil because the data can change and the change is seen visually in a graph. One standard used when creating this sketch is SMP #1, Making sense of problems and persevere in solving them. Students engaged in this habit of mind by trying to come up with the slope and y- intercept. In order to do this, they have to show patience while also checking their answer a different way. Another standard that I used was SMP #4, Model with Mathematics. Students engage in this standard by applying prior knowledge of the relationship between the slope and y-intercept on a graph. They used a representation to solve a real life problem and applied equations. The thing I like most about my project is the hide and show buttons because students can try to predict a graph with out seeing the answer first.
