The Other Side of Zero
NCERT Ganita Prakash for Class 6, Chapter 10, The Other Side of Zero, begins with temperatures below zero, basement floors, and money owed. It extends the number line past zero to negative integers, orders positive and negative numbers by position, and reads opposites across zero. Children add and subtract integers by moving on the line, connect debt and withdrawal stories with signs, and check patterns in sums. Seeing zero as a boundary rather than nothing prepares the full system of signed numbers.
