The frog invites you to make a frog jump from water lily to water lily by adding or subtracting the indicated number (from 0 to 100).

- Levels:
Among several intervals, you must choose the length of the frog's jumps.
Each part offers 2 additive sequences and 1 subtractive sequence. The frog jumps from water lily to water lily, avoiding falling into the water.

- Scoring:
The frog must reach the star on the last water lily. Attention: if it falls in the water, 1/2 star is removed from the reward to be reached.
A maximum of 3 stars can be obtained in each game. (Only the best scores remain in memory).
To reset the scores, click 5 times on Serge the llama on the home screen.

- Options:
A button allows you to mute the croaking of the frog.


This application is part of the mathematics programs of cycle 2 (France):
- Iterate a sequence of 1 in 1, 10 in 10, 100 in 100.
- Mental calculation: calculate without the support of writing, to obtain an exact result.
* Name, read, write, represent whole numbers (expected at the end of cycle 2)
* Calculate with whole numbers (expected end of cycle 2)
