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, going from number grids in the 100s to the 1000s.
This is an ActivInspire ActivBoard file that you can open for the students to use during center time or rotations.
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 PDF if you prefer to run the center with actual hard copies of the number grid puzzles (this is what I do and then laminate for reuse).
Please find the corresponding PDF file in my store to see exact images of what the number grid puzzles look like. :)
