come on man... I know I'm not the best at math but I think there's a point where I can tell I'm just being gaslit by the site.

Delta Math: The Online Math Learning Platform Helping Students Master Skills

In today’s digital classroom, math is no longer limited to textbooks and worksheets. One of the most popular tools teachers and students use is Delta Math, an online platform designed to give students targeted math practice and give teachers powerful tracking and grading tools. From middle school algebra to high school calculus, Delta Math helps learners build confidence through practice, feedback, and repetition.

What Is Delta Math?

Delta Math is a web-based math learning platform used mostly by grades 6–12 students and teachers. It offers thousands of automatically generated practice problems across a wide range of topics such as:

Arithmetic and pre-algebra

Algebra 1 and Algebra 2

Geometry

Trigonometry

Pre-calculus and calculus

Probability and statistics

Students log in, complete assignments or practice sets, and get instant feedback, while teachers can assign work, monitor progress, and see where students are struggling.

How Delta Math Works

The core idea of Delta Math is simple: Practice → Instant feedback → Learn from mistakes.

1. Teacher Creates Assignments

Teachers choose:

Topics (e.g., solving equations, graphing functions)

Difficulty level

Number of questions

Due dates

Assignments can be used as classwork, homework, quizzes, or test review.

2. Students Solve Interactive Problems

Students then:

Log in from school or home

Open the assigned set

Answer randomized questions

See immediately if their answer is correct or not

This week I have been exploring the world of the flipped classroom, and the biggest headache for teachers across content and grade-level when introducing the flipped classroom model is building enough content to allow students to explore a unit independently, so that when they come back to the classroom students and teachers can focus on more complex applications of the concepts learned at home. Rather than spending hours with Screecastify teachers have tons of resources to deliver initial content to students effectively while freeing up time for teachers to focus on engaging classroom activities. As an Instructional Technology Specialist at a large Texas High School, I hear teachers from all subject areas saying that there just isn’t as much content out there for what I teach. So rather than focussing on one content area, I will break down the best pre-made, ready-to-go content libraries across all four core subjects and even some electives. 

   Khan Academy is one of the foremost pioneers in independent learning modules. This site sets up their modules into courses that are divided into units. Each unit has videos, articles, and other assorted resources for students to review. Students then take mastery quizzes at the end of each unit to prove that they mastered the content in the unit. Khan Academy’s resources can be accessed through a link without logging in, so teachers can use the resources without having to assign or track progress through Khan Academy if they do not wish to. For my high school teachers all four core areas have some amount of content available to them. Khan Academy offers specific math courses in Algebra 1, Geometry, Algebra 2, Trigonometry, Pre/Calculus, Statistics, and three AP math subjects. For Science Khan offers Biology/ AP Bio, Chemistry, Physics, Environmental Science, and Astronomy. History/Social Studies is listed under the title of Arts and Humanities and includes AP/US History, World History, US Government, Art History. I also have my Senior Economics teachers who are listed in their own category, but Khan has both Macro and Micro broken down into their own courses with an AP course included. The problem with Khan Academy is that it does not have much content for high school level language arts, and My World Geography teachers were not explicitly included in the Khan Academy courses. There is a 9th grade ELA course currently, but it focuses primarily on reading comprehension and vocabulary skills. I suspect this is due to the difficulty in assessing writing through artificial intelligence though with Grammarly improving in that realm we may see a change in this sooner rather than later. Khan Academy also offers SAT practice, Computer Science Courses, and AP/On-level Art History. The primary affordance of Khan Academy is for students to work through modules independently, but the ease of outside access to the instructional materials housed in each unit makes it just as effective as a traditional online database for teachers. 

Nearpod has been working their tails off building a library of content and partnering with outside learning applications. 

Their large library of videos, interactive activities, and pre-made, customizable  presentations integrate the likes of Desmos, Phet Labs, Newsela, Quill, Flocabulary, BBC World News, National Geographic, PBS, and our old friends Khan Academy just to name a few. This is where my ELA teachers get their content fix after the let down from Khan Academy. The content in the Nearpod library is made to easily drop into their main product which is their interactive presentation platform, so the resources cannot be linked to outside of nearpod, however; a free subscription to nearpod enables users to utilize some content from the library. Posting the content is then just a matter of posting the presentation with the content and even assessment included. This is not a bad adjustment in the flipped classroom setting since teachers are often searching for ways to encourage students to complete at-home assignments. Content is available for English 1-4, Biology, Chemistry, Physics, US History, World History, and World Geography. Even though the draw activity (pictured below)  is conducive to writing out math problems, the math content included in the Nearpod library is limited to elementary-level math with the exception of the Desmos integration. This is great for focussing on graphing and system functions, but it is not applicable across the math department. Nearpod really shines as a database of content with a premium subscription to afford teachers the breadth of the integrated third party applications. 

DeltaMath solves the challenge of creating new, differentiated problems for students in math classes. This web-based program generates practice problems for students to answer and organizes these problems by common core standards. These standards correspond with high school courses which can be assigned by teachers to students through the application. Mathematical concepts are explained through text examples rather than videos, and students/teachers must log in to Delta Math to access the content. High School courses available in DeltaMath include Algebra 1, Geometry, Algebra 2, Pre-Calculus, Calculus, and Computer Science. While this platform may be lacking in the explanation of skills, the time saved by teachers not having to create new practice problems can free up time to focus on teacher exemplar videos and application activities.
