Free 8th grade math games and practice

On screen this path is called Level 10, so a child never has to think about which grade they are "supposed" to be in. A part is finished by ten right answers; a wrong one makes the next problem a little easier and never costs anything.

The lesson parts in 8th grade math

The first 24 of 128 parts, in the order Peabody lists them:

1. Slide a point: Right and up add; left and down take away
2. Slide a triangle, undo a slide: Find the move, or go back to the start
3. Flip over an axis: Over the x-axis, y changes sign
4. Flip over a line like x = 2: Same distance from the line, other side
5. Turn about the origin: Half turn, and quarter turns
6. Clockwise, counterclockwise, and back: 270 counterclockwise is 90 clockwise
7. Which move?: Follow one corner to see the move
8. Two moves, in order: Order matters: do the first move, then the second
9. Matching parts: Congruent figures have equal matching parts
10. Congruent, perimeter and x: Equal angles help you find x
11. A line crosses two parallel lines: Vertical and corresponding angles are equal
12. Alternate and co-interior angles: Equal or add to 180, and find x
13. The angles of a triangle: The three angles add up to 180°
14. The outside angle and x: Outside angle = the two far inside angles
15. Scale a point from the origin: Multiply each coordinate by the scale factor
16. Fraction factors and other centers: Scale the distance from the center
17. Similar triangles: Same angles, sides in the same ratio
18. Find a missing side: Shadows, heights and matching sides
19. Area grows by k times k: Double the sides, four times the area
20. Area and the scale factor: Work backward from areas to the scale factor
21. Up, down, flat or straight up: Read the direction of a line
22. Slope from a graph: Count the rise and the run
23. Fractions and negative slopes: Down to the right is negative
24. Slope from two points: Change in y over change in x

What practice starts on

Beside the lessons, the practice brain brings facts back on a schedule. For a 8th grade child it works on multi-digit arithmetic, fractions, decimals and percents, negative numbers and algebra, times tables and division facts. The whole math ladder, lowest rung first, is counting, making ten, adding, taking away, number sense, times tables, division, big numbers, fractions, decimals and negatives and algebra; a child starts on the rung their grade puts them on and moves up when answers are solid, so a child who is ahead is not held back and a question answered right is done for good.

Free games that ask 8th grade math

Every answer is three big boxes to tap, with no typing, and a wrong answer costs a little time, never a life. 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.

Questions parents ask

What does Peabody's 8th grade math cover?

128 lesson parts across transformations, congruence and similarity, slope and linear relationships, linear equations and systems, functions and volume, associations in data, exponents and scientific notation and pythagorean theorem and irrational numbers, from slide a point to word problems to a tenth. They are short, they are made and marked by code, and they are not matched to state standards.

Does my child have to do the parts in order?

No. Every part is open. The first one not yet finished is marked "Up next" as a suggestion, so a child can go to whatever the class is doing this week.

Is it free?

Yes, free through the end of 2026, with no sign-up. Peabody has no written work, no standards report and no test, so it is practice, not a full curriculum.
