Here is a FREE worksheet on adding 10, 100, and 1000 written by a National Board Certified Teacher.
Most people would be surprised at how much difficulty students have with place value in general and with adding 10, 100 and 1000 in particular. To us grown-ups, it seems simple: find that digit in the number and change it to the next digit up. For kids, this is often a challenge. If they can set up the equation, they’ll do okay—unless they line up their numbers incorrectly!
Cumulative review programs like Mountain Math try to address this by having the students add 10, 100 and 1000 to numbers with each session. However, it’s up to the teacher to actually explain the process.
