Celebrating Hispanic & Latinx Heritage Month

Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Project

In our math classroom, the right tools make all the difference. I am seeking funding to acquire 200 TI-30XS Multiview calculators so every student has reliable, equal access to the technology they need to succeed in standard math coursework and standardized testing.

This TI-30XS is a game-changer for creating equal access for all high school students; its multi-line display allows students to see math notation as it appears in textbooks, step-by-step calculations, and fraction conversions side-by-side.

Having a class set ready for daily instruction, practice, and test days will level the playing field for all my learners—removing technology barriers so they can focus on mastering concepts and building confidence.

Your support directly equips my students with the exact tools they need to unlock their full mathematical potential. Thank you for making a lasting impact on my classroom!

This project will directly impact historically underfunded classrooms.
