One family account. Each child gets their own space. Parents get a Teacher view with everything they need to help.
A question that points the right way: “What do you need to find first?”
A specific method: draw a bar model, find one unit, make a list of multiples.
Reveals one step of the worked solution at a time.
Every step and the answer, followed by a fresh problem just like it.
Parents see hints per day and per skill, so “needs help” is based on what actually happened.
Using a hint is how you learn. Kids earn a bonus for solving on their own, not a punishment for asking.
