Extra Credit: Math Games

Choordinator

About this game

Extra Credit is two math games in one app. Pick a game on the first screen and play. In both, right answers help you win.

PUSHBACK: SNOWBALL FIGHTS WITH MATH BREAKS
Lead a team of kids in blue scarves in a giant snowball fight. Slide your snow cannon, send teammates through the gates and push the Reds back across the snowy field. Every so often the match stops for a quick math break: a few problems, one at a time, no timer. Every right answer sends more teammates into the fight. A wrong answer costs nothing.

- The Long Winter: a 100-level campaign across ten snowy chapters.
- Classic: run the neon road, knock back the wobbly jelly Gloop and meet a big boss at the end of every world.
- Gear Shed: spend coins on upgrades and find nine snow throwers, from the Snow Scoop to the Snow Blower.
- Floodgates and the endless Gauntlet for when you have done it all.

SUMHAVEN: BUILD A CITY, HATCH CREATURES
Every right answer sets a block in a little harbor city. Finish a bakery, a clock tower or a fish market and watch the town come to life. Right answers also warm eggs, and every egg hatches a one-of-a-kind creature that moves into town and works in the buildings. Collect them in the Book, help them grow, and make friends with the wild creatures that sail in by boat.

MATH THAT FITS YOUR CHILD
Pick a grade from Kindergarten to 8th grade, or focus on adding and subtracting within 10, 20 or more. Problems a child misses come back soon. A progress page shows which facts are solid and which still need work. The math settings sit behind a grown-up question, so a player can't switch practice off or pick easier problems alone.

HOMEROOM FOR GROWN-UPS
Homeroom is a website for families, free to join (the full progress view is a one-time purchase after a free month). Each game has a save code on its Grown-up page. Add the code in Homeroom to follow your child's practice and set the math from your own phone or computer. The save is backed up there, so a new phone can pick up where the old one left off.

CLASSES FOR TEACHERS
Teachers can make a class in Homeroom and hand out a class code. Children type the code in the game, tap their name, and the teacher says yes.

FOR FAMILIES
- No ads
- No in-app purchases
- No account or sign-in needed to play
- Plays offline; the save backs up to Homeroom when the phone is online
- A gentle cartoon snowball fight with no blood: a Red who is knocked down just fades out to go warm up.
