AlphaNumbers is a daily practice program designed to build fast, accurate recall and fluency of math facts, starting with early number sense and progressing through addition, subtraction, multiplication, and division.
Smart Placement: A quick initial placement test assigns your child to the exact right starting Learning Track.
Daily Assessments: Every session begins with a short assessment to measure current fluency and unlock higher tracks as speed targets are met.
Adaptive Learning: Between assessments, children learn new facts, build accuracy, and sharpen their recall against shrinking timers to ensure true mastery.
How to log in
Apps in TimeBack log in automatically as standard. If the automatic login doesn't work, follow the steps below.
You can also sign in using Google Single-Sign-On (SSO) - your child clicks “Sign in with TimeBack SSO” and signs in with Google using their @2hourlearning account, with their password provided on your parents portal.
Open TimeBack: Sign in to TimeBack with your child's student email and find the “Fast Math - AlphaNumbers” course on your “Home.”
Launch AlphaNumbers: Open the "subject tab" and click Jump In.
Sign in: You will be auto-logged in. If you are not, click “Sign in with TimeBack SSO” and use your child's student email (@2hourlearning) and password.
Take the placement test: On first use, a short placement test sets the starting track.
First Time Setup
The first time your child logs in, they will take short placement tests (about 2 minutes each) to determine which math facts your child already knows and which ones they need to practice.
Based on the results, the app assigns a starting Learning Track, which is the grade level they will work on.
How a day works
Each day starts with a short assessment that checks fluency on the current track; meeting its Speed Score target (fast, accurate answers) moves your child to the next track.
Then comes practice: new facts are introduced with their answers, reviewed untimed for accuracy, then practiced against a timer.
An Accuracy stage (no timer) drills any facts your child is missing until they are able to remember them correctly.
A Fluency stage builds speed against shrinking timers; 6 seconds, then 3, 2, even 1.5, and your child must clear each level to advance.
A progress bar fills only on fast, correct “green-zone” answers; late “yellow-zone” answers, mistakes, and timeouts don't move it forward.
How XP works
XP is awarded by:
Maintaining above 80% accuracy
Hitting 100% accuracy earns bonus XP
1 XP = 1 minute of practice at 80% or higher accuracy.
Only active time (thinking, typing, moving between questions) counts; idle time is trimmed, and a practice session under 80% accuracy earns 0 XP.
One important Note: AlphaNumbers sends its time and XP to TimeBack when your child moves between pages, so they should finish the activity they're on and return to the home page before closing the app, otherwise that session's progress may not be recorded.
Habits that lead to success
Practice about 10 minutes a day in short sessions with breaks, daily beats long and occasional.
Aim for the green zone: only fast, correct answers count toward mastery.
Don't guess or let the timer run out; best effort on every fact.
Never restart or refresh the app. It sends your child back to the start of the practice.
Type with the keyboard or touchscreen (not the mouse), and answer from memory rather than counting.
How to Check Progress
AlphaNumbers tracks your child's progress inside the app. On the home page, your child can see:
Progress Grid: Shows the mastery status of each math fact on their current Learning Track. Facts move through stages: Not Started, Learning, Accuracy, Fluency, and Mastered. This makes it easy to see which facts are solid and which ones still need work.
Speed Score: Shows your child's current speed score on their Learning Track, how it compares to their last test, and how many more points they need to reach their fluency target for that track.
XP Progress: Shows daily XP earned based on practice time and accuracy.
Estimated Time to Complete: Shows how close your child is to finishing their current Learning Track.
How to tell it's working
Progress shows up as facts moving across the grid toward Mastered, a rising Speed Score, and passing the daily assessment to unlock the next track. Because only green-zone (fast and correct) answers count, watch that rather than time alone, a lot of minutes with little grid movement usually means guessing, rushing, or counting instead of recalling. Short, focused daily practice is what moves it.
Common Issues | FAQs
How does my child log in?
AlphaNumbers auto-signs you in on TimeBack. You can also sign in using Google Single-Sign-On (SSO) - your child clicks “Sign in with TimeBack SSO” and signs in with Google using their @2hourlearning account, with their password provided on your parents portal.
TimeBack shows less time or XP than my child spent
AlphaNumbers reports active time, the time actually spent answering (thinking, typing, moving between questions), not total time, so idle time is trimmed. XP is about one point per active minute, and a session under 80% accuracy earns none. Tip: have your child finish the activity and return to the home page before closing, so the session's data is sent to TimeBack.
What do the colors or “zones” mean?
Answers are timed: a fast, correct answer is “green zone” and counts toward mastery; a correct-but-slow answer is “yellow zone” (still building speed); mistakes and timeouts don't advance the progress bar. The goal is steady green-zone recall.
My child keeps practicing the same facts
That's the design. AlphaNumbers keeps a fact in practice until it's both accurate and fast (recalled within about 1.5 seconds), then marks it Mastered. The Progress Grid on the home page shows which facts are still building. Restarting or refreshing only sends them back, so it's best to keep going.
How much should my child do each day?
About 10 minutes a day at over 80% accuracy, ideally in short sessions with breaks daily practice builds fluency far better than occasional long ones. A focused 10-XP day keeps a child on pace to cover roughly two grades of facts a year.
Fast Math disappeared from my/my child's dashboard
That usually means they finished it. Once your child passes every track through the top grade level (until Grade 5), the system automatically unenrolls them and Fast Math drops off the dashboard.
