Hello Jack! ^^

                I am glad that you still do your homework though you have a lot of things to do. I am happy as well that you are getting more knowledgeable in many areas. Keep it up!
            Last Wednesday, we discussed what is a Present Progressive Tense and we had an activity. I also assigned you to answer write questions in Present Progressive.

1. Robin / to ride / his bike
2. where/ she/ to go
3. what your mother/ to do/ now

Here are you answers and with corresponding corrections:

is robin going to ride his bike?
> This sentence is correct. But we have Capitalization Rule.
(The first letter of every sentence should be capitalize.)

what are your mother going to do
> What (is) your mother doing now? 
(First letter of the question word should be capitalize and remember,we are referring to one person which is the mother so we will use the verb is plus the -ing form. )
> Don't forget to put the correct punctuation mark.  Appropriate use of punctuation mark shows that a  person has a good knowledge of grammar.

where is she going
>The same with this asking sentence.

Take good care of yourself, Jack and always stay motivated.  I will always be your backbone. ^^
