In this interactive, students arrange train carriages according to numbers on their sides (these are represented by words, numerals, dice dots or counting frames). Students identify the numbers that come before and after starting numbers. There are five levels. At Level 1, students can numbers from 0 to 10 are presented. At Levels 2 to 4, larger numbers are given. At Level 5, students can practise 'skip counting' by twos, fives and tens to arrange the train carriages.
