Frequently asked questions
Standards and courses
What do codes like 6.RP.A.1 mean?
Each code names one Common Core math standard. Read 6.RP.A.1 as grade 6, the Ratios and Proportional Relationships domain, cluster A, standard 1. High school codes, such as HSA-SSE.A.1, start with the subject area, such as Algebra, in place of a grade. Each tile on Home is one standard, and Learn shows its official text.
What is the Common Core, and what about my state?
The Common Core State Standards are the K-12 math goals HBL teaches. Most states teach them or standards close to them. Set your family's state in the parent area's Settings: a Colorado family's children also see the few additions in Colorado's math standards, which Learn notes where they apply.
Why does practice start with some standards first?
Some clusters carry most of a grade's weight on state tests, so a session plan reaches those standards first.
Which course should my child be in?
A new profile starts in the course for its grade, or in Grade 6 when its grade has no course of its own. Courses lists every course from Grade 3 through Algebra 2, and your child can open any of them. Make this my course, on Courses or at the top of an open course, makes it your child's current course.
Practice
How do I know my child has learned a standard?
A standard counts as learned once your child gets at least 80% of its latest problems, up to five, right on the first try with no hints, and at least three of them. A problem whose answer your child revealed counts as a miss. Home and Courses show this progress for each standard.
How do flashcards decide what comes back?
Each time your child answers a card right on the first try, it comes back later: after 1, 3, 7, 16, then 35 days. A miss, a revealed answer, or asking the coach about the card brings it back at the end of the session and starts its schedule over. I know this skips a card your child already knows, and it comes back in a week or more.
What if a problem is wrong?
Press Report on the problem, pick a reason, and add a note if you like. A reported problem stops counting toward your child's progress, and the report shows in your parent log.
Why is there a daily limit?
An AI model writes each new problem and each coach reply, so each child gets a daily number of new problems and coach messages. Cards and lessons still work past either limit, and more problems and messages come at midnight in your time zone.
The AI coach
Does the coach give my child the answers?
No. While a problem or flashcard is unfinished, the coach guides with one question or hint at a time, and points to Show answer if your child asks for the answer outright. Once your child finishes, it explains the solution. The help page for parents covers what the coach sees, what it talks about, and how it keeps your child safe.
Can I see what my child and the coach said?
Yes. The parent area's Activity tab shows each child's messages and the coach's replies, newest first, with work reviews and reports. Clearing the chat makes the coach forget it, and the log keeps it.
Your account and data
Can more than one child use one account?
Yes. Add a profile for each child in the parent area's Children tab, and each one keeps its own course, progress, cards, and coach chat. The app asks who's practicing after sign-in, and the child's name in the header switches to another profile.
What if I forget the parent PIN?
Press Forgot the PIN? on the PIN prompt, and HBL emails you a sign-in code. Enter that code with a new PIN to replace the old one. Every parent in the family gets an email saying the PIN changed.
How do I stop or change the weekly email?
The Weekly email panel in the parent area's Settings turns it off or picks another day and hour. The unsubscribe link at the end of any weekly email also turns it off.
What do you keep about my child, and how do I delete it?
HBL keeps each child's profile, practice, and coach chat under a nickname, with no real name, school, or photo. The Your data panel, on the parent area's Privacy & data tab, exports a child's data as one file and deletes a profile or the whole account. The consent notice lists everything HBL collects and how long it keeps it.
