What's on this sheet
Adding a negative is subtracting; subtracting a negative is adding. Stated as rules they blur together, so practice is the thing that makes them stick. Sheets mix the two operations across a chosen range so a child meets every sign combination rather than one at a time.
Why this sheet works
Integers are the doorway to algebra, where negatives appear on both sides of every equation.
How this one works
One question from this sheet, worked through a step at a time.
8 − 10
- Put a counter on 8. Everything else is which way it slides and how far.
- Taking away a positive moves left, the way it always has.
- So slide 10 to the left, from 8 to -2. 8 − 10 = -2.
