Calculation Cards - First Grade - Addition & Subtraction These are cards my child used when they were in first grade. The name was written on the cover of the first card, so I erased it with correction fluid and correction tape. I think the contents are in good condition. I erased the name on the case with a permanent marker. Please use a name sticker or something similar. I checked the contents of the cards and they were all there, so I put them back in order. Please understand that these are used items.
