Sparkle Zoo Number Challenge

Sharpen your kindergarten to middle-school arithmetic skills! Progress through 50 levels (including 8 reviews) named after increasingly clever animals. Topics include simple counting, arithmetic, fractions, decimals, percents, equation-solving, and more.

While proficiency is enough to progress to the next levels, true mastery is needed to collect every star. The best stars can be collected only by answering many questions in a row quickly and correctly.
