It looks like Google translator was used. At least it agrees with the translation.

The worst thing is to control how they made the corrections requested by the author and where they randomly added new errors in the process.

My version (words under titles are revealed in square brackets):

“Книга <...>я Дмитрѣева с[ы]на
а дана по[л]гри[в]ны
<...>хтоъ за нѣнь приме[т]ца
то[т] будеть ума ня<...>”

Something like that in modern Russian:
“Книга ... Дмитриева сына, а дана полгривны, ... кто за неё примется, тот будет ума...”

The title page is very reminiscent of the very rare Ivan Fedorov's Azbuka of 1578. However, there are differences (see facsimile). The book's name is the same (“Начало учения детям, хотящим разумети писание” in modern spelling).
