The package includes 64 days worth of number of the day activities. This would be great to use as morning work. I developed this packet to help kids develop number sense and increase their understanding of place value. This packet could be started in the middle of first grade or the beginning of second grade. I plan on adding a second number of the day starting with 101. I would suggest that you have your students write a story problem on the back of each page that goes with their number bond if they finish early. This can be differentiated because students can choose how they decompose their numbers. I did not include an answer key because answers can vary.
