The arcade also has two action games with cartoon violence, Sniper and Doomcrawl. We leave them off these lists on purpose; every game is on the games page. A game's "From" grade is where it is made to start; its questions follow the grade a child says they are in.
Which grades work on negatives and algebra
The practice brain works on negatives and algebra for 5th grade, 6th grade, 7th grade and 8th grade. It starts a child on the rung their grade puts them on, then moves up when answers are solid, so a child ahead of their grade is not held back.

Questions parents ask
Do these games need typing?
No. Every answer is one of three big boxes, so a child who cannot type or read well yet can play, and a wrong answer costs a little time, never a life.
Do they ask the same questions every time?
No. Questions come from the same practice brain behind the lessons, which brings negatives and algebra back on a schedule and does not ask again what was answered right.
Is it free?
Yes, free through the end of 2026, with no sign-up. The games teach and review; Peabody is not a full curriculum and gives no test or score against other children.
