Today's grammar for Danny

Today we started late with the first lesson,because i promised Danny that we'll go to the market before.Just to add some more stuff to his Ben10 gear.He decided for the cellfone.He did even on the weekends on his own some more maths,so we're not in hurry.

Back home he went to the computer and asked for doing the Übfix grammar programm,hard to belive i know.:)
Then we started with "d or t".Danny readed the whole sentence and had to add the right letter by himself,by the keyboard.I helped him only with suggestions,like if the letter is the last one in the word put the word in plural,makes it easier and so on.
He needed 41 minutes for 10 tasks,which is imo acceptable for a first grader.
By the way,the programm is for the basic school,not particular for the first grade.
Here the result:
