Pencils up! Play UNICEF's Math for Good Challenge.

Take the math challenge today to help get children into school and out of poverty.

You have one minute — every problem you solve will unlock a $0.25 gift to UNICEF. But stay sharp: the questions get harder as you go, and when time runs out, the game's over.
