The activity seems good. I would have the students listen and try to write the words on their own first, maybe listening twice. Then, I would write the words on the board for them to try fill in any they couldn't get or to check their spelling. That gives the better students a challenge to do it on their own, but also helps struggling students at the end.

On a website front, you're trying to send users to your site and then from your site to TpT. From a user standpoint, it would be better to just send them to the TpT post with the information and the downloads all together, or have the file also available on your blog.

From a Google standpoint, I think your blog will be logged as duplicate content. TpT ranks higher and since you have the same information in 2 places, they are more than likely to take the first and view your blog post as scraping or a duplicate.

You never really know with Google or other search engines, but I would concentrate on one or the other. Do you want to promote your blog, or do you want to promote your TpT profile?
