1. Scootpad: https://www.scootpad.com
This resource is a great resource that allows students to work on assignments in a self-paced format. My students love working on Scootpad due to the vast amount of rewards they can earn from completing assignment. Scootpad also offers very rigorous assignments that require students to think in critical ways. Teachers can sign up for a FREE account and start using some of Scootpad's features. However, teachers would need to purchase the full version in order to benefit fully from this resource. I assure you it is well worth the money. My students love working on Scootpad so much they will work on it at home on their own time. The assignments are so engaging that students do not even realize they are doing school work.
2. TenMarks: https://www.tenmarks.com
This resource is one that is completely FREE to teachers. This site allows students to work on engaging, rigorous assignments that challenge their ability to think and reason about mathematics. This resource will allow teachers to assign students assignments on TNReady aligned standards. I use this resource weekly in my classroom and I am starting to see great gains in my students. This resource will challenge students and will allow them to work out their problems by giving them hints and videos to assist them while they work. I really recommend this resource to all teachers.
As Tennessee adopts a different Achievement test in TNReady it is vital that teachers find rigorous resources to help assist students in the way they thing think and solve problems. I firmly believe that students need to be challenged. If students are challenged in the correct way they will rise to the occasion and show growth. These two resources both challenge students while given them the rigorous assignments that they need in order to be successful on the TNReady assessment.
