I made these number grids to be somewhat of a challenge for my students. Some of the number grid puzzles I have found for my students have been too easy, so I made these leveled for my students. There are 3 different sets of puzzles, with 10 in each set, going from number grids in the 100s to the 1000s for a total of 30 number grid puzzles.
I laminate these and put them in my math center rotations for the students to practice.
Can be used for grades 1 - 3, although I did make them specifically for my third graders.
Also, I have this file uploaded as a Promethean file if you prefer to run the center on your ActivBoard. Just an FYI that they are the same puzzles so that you don't accidentally purchase both.
