3 levels are included:
- Level 1: Students need to work out what number has been subtracted e.g. if there are two jumps of 10, and four jumps of 1, then the number 24 has been subtracted
- Level 2: Students work out what number has been subtracted, as well as record the jumps along the number line
- Level 3: students record the numbers along the number line, the number added, and the total.
This activity is included in The Hive's Math program for FORMING MULTIPLES OF 10 FOR SUBTRACTION (Grades 1 & 2).
