How To Use Ti-30xs For Algebra

Click for resource → pdf → docx

Students do not demand to know how to enter functions into the TI-30XS, but for teachers want to incorporate more than calculator explorations into their classes, hither are two features of the computer worth knowing about. The pdf link to a higher place is a fix of pace-by-step instructions. The docx link is the aforementioned, but I included it in case teachers desire to tailor the instructions specifically for their students.

Using the figurer to play the Function Game

This is a good activity for teachers who are using (or reviewing) Unit of measurement i of the CUNY HSE Math Curriculum Framework and want to give students some practice with the TI-30XS calculator.

In Unit 1 of the CUNY HSE Math Curriculum Framework there is an action called "My Teacher is a Estimator" and another chosen "The Function Game".

"My Instructor is a Computer" comes in the beginning of the lesson, where the teacher has a function rule in their head. Students take turns giving numbers to input into the teachers function and the teacher tells students what number comes out with each input. Students go on track of the inputs and outputs and employ the growing table to try and guess the office dominion.
"The Function Game" comes at the end of the lesson (there are 2 other activities betwixt "My Teacher is a…" and "The Office Game"). In this activity students come up with a role and then use that function to fill up out some input/outputs a table. Then they give the table to another student, who then has to figure out the function rule.

The HSE calculator – the TI-30XS – has a feature that allows students to enter a function into the calculator. They they tin can set the calculator to take inputs from some other student and give the output. The other student tin can keep putting in numbers until they are able to approximate the part. It is a kind of a combination of the two activities above.

Hither'south a brief video to show y'all how it can be done:

Using the calculator to create a role (In/Out) tabular array

You tin can also enter a role into the calculator and get a completed input/output table. It is a very similar ready-up as using the calculator to play the function game, except for one step, which is described in the pace-by-stride instructions. Basically, when you get to the carte du jour of three options, instead of choosing "Inquire-ten" you lot choose "Auto".

I'm curious as to how teachers might use this feature of the estimator with students, so delight share any ideas you have in the annotate department below.

What are some benefits to showing students how to enter a role equation and get a completed table of input and output values?
What might be some interesting part equations students could enter and then do a discover/wonder with the completed function tabular array?
