title: Katrina's progress with learning mathematics.
abstract: Katrina is 10 years old and has Down syndrome. She is making good progress with learning and numbers and mathematics. We describe how Katrina has learned number concepts and arithmetic skills over several years. We highlight the influence of early learning habits, visual supports, motivation and practice, and the uses made of different number teaching schemes.
