I am trying out a little experiment here. I have written 4 math homework problems for my second grade class in this Google Doc: https://docs.google.com/document/d/19JwQEkx9MghSQVwtPHjsIm5r6p8oYFCdmNgGCy2Z-Y4/edit?usp=sharing
These problems fit in with Operations and Algebraic Thinking. Feel free to copy and use. Let me know in the comments section if it works for you. I'll do more of this in the future if this works.
