Reminders & Tips
for this worksheet:
- A Reminder: Refresh your Addition to 18 skills.
- Only add the "non-zero" part of numbers, and "ignore" the zeros. Then when you're done - put the zeros back into game.
- "Break" the second addend to complement to a 100 with the first one. Then simply add the rest. :-)
