Here is a checklist for parents (and kids) that struggle with the question “What to bring on the first school day”.
Majority of schools have the basic things that are necessary in the beginning of the year but just in case you can have things like pencils , eraser is also good, a notebook or a few papers (white are pretty good).
Then if you want your kid to use more advanced things you can add him/her some scissors, glue or even pencil sharpener.
To carry all these stuff a small backpack is necessary in which you can as well add a water bottle and a lunchbox.
Now these are the basic things any kid should have at least to be able to perform some activities that may involve drawing, writing or highlighting.It would be very good a handwatch to be added to the inventory items (even though every classroom can have one on the wall).
A very good school shop can provide all these things so check out in your neighborhood and purchase what is needed for a wonderful first day in school experience 🙂
