Foldaroo teaches K-6 math so it makes sense. Most skills start with pictures, move to numbers, then to word problems. If your child has fallen behind, Foldaroo begins where the gaps are, not at their school grade.

Pay once. No subscription. No ads. No accounts. Works offline. Kindergarten and 1st grade are free, and one purchase by a grown-up unlocks everything else.

SEE IT, TRY IT, SOLVE IT
Each of the 97 skills is learned in three small steps:
• See it: most skills open with pictures, such as ten frames, number lines and fraction bars
• Try it: practice the same idea with numbers
• Solve it: use the skill on word problems and harder questions

STARTS IN THE RIGHT PLACE
A short, friendly warm-up finds where your child should begin. It is not a test. A 4th grader with gaps in 2nd grade math starts by filling those gaps.

New skills open when the skills they depend on are in place. If a step keeps going wrong, the app steps back to the skill underneath it for a quick power-up, then returns.

MISTAKES ARE PART OF LEARNING
A wrong answer gets a clue and another try. If it is still tricky, the app works through the solution one step at a time. The lesson then ends with extra practice.

WHAT YOUR CHILD LEARNS, GRADE BY GRADE
97 skills. The app follows the US Common Core standards:

HOPPER READS IT ALOUD
Hopper, the paper frog, reads every question and clue in a warm, clear voice, and the worked steps up to 2nd grade. With read-aloud on, lessons use more than 5,000 recorded questions.

PRACTICE THAT DOES NOT RUN OUT
With read-aloud off, questions are created fresh every time. A quick daily workout brings back older skills.

A PAPER FOLD EVERY FIVE STARS
Each grade is its own world, from Clover Meadow to Star Summit. Each star your child earns draws a crease on a flat sheet of paper. Every five stars, the sheet folds into a new Fold: an origami-style paper frog, butterfly, fish, rocket and more, each in 5 colors of paper, 60 in all. Your child picks a first Fold as a buddy that cheers them on. No timers and no lives.
