I want to make a box for my daughter in order to fill in the blank. But it is not nice. How can I repair the boxes?

Here is a suggestion:
\documentclass{article}
\usepackage{amsmath}
\newcommand{\pbox}[1]{\boxed{\phantom{#1}}}
\begin{document}
$ \pbox{2015} + 2016 = 4031 $
\medskip
$ \pbox{1} + \pbox{2} + \pbox{3} = 6 $
\medskip
$ \pbox{f(x)} = ax^2 + bx + c $
\medskip
$ \dfrac{6}{10} = \dfrac{\pbox{3}}{5} $
\end{document}
The contents is set as a \phantom inside a \boxed (from amsmath).

@Werner HOw can I simplify this line
$ 12\,\, \pbox{>} \,\,5 + 6.$? – minhthien_2016 Dec 28 '16 at 2:00 -

@Werner Can I get a square box? If I use
$ 12 \mathbin{\pbox{>}} 5 + 6 $not nice. – minhthien_2016 Dec 28 '16 at 4:00 -
@toandhsp: Try with
$ 12 \mathbin{\pbox{\vphantom{>}\rule{1ex}{0pt}}} 5 + 6 $. – Werner Dec 28 '16 at 7:08
\vcenteroption. There are other ways, but I think this suffices. – nox Dec 28 '16 at 0:52\[\vcenter{\hbox{\rule{0.35cm}{0.35cm}}} + 2016 = 2017 \]. – minhthien_2016 Dec 28 '16 at 1:20
