Mathlings: Decimals & Percents

Build a bridge with fractions, decimals and percents!

Mathlings: Decimals & Percents turns the trickiest part of school maths into a cheerful harbour adventure for children aged 6 to 14. Pick a Mathling buddy, sail between eight islands of Bridge Bay, and earn coins to build a harbour town — cottages, a lighthouse, a Ferris wheel, a rocket and ten landmarks, all the way to the Great Bridge.

EVERYTHING FROM FIRST FRACTIONS TO PERCENT CHANGE

33 games × 5 levels, from grade 1 / Year 2 to grade 8 / Year 9. Levels are chosen for your child's age.

FRACTIONS THE WAY CHILDREN WRITE THEM
Every fraction is shown stacked — numerator over denominator — in questions, answers, explanations and printables. Children type fractions in real boxes, tap the number line, shade parts of bars, pies and hundred squares, and put numbers in order. A wrong answer gets a second try, then a clear worked explanation.
