Thank you for all that you do in developing new content and updating older content on Khan Academy! I look forward to this post every month so that I can keep track of new exercises and, now especially with the new dashboard design, new articles and videos in subjects which I have already completed.

In May/June 2018, three new exercises were added to 7th grade math. I was alerted to their presence because, in my subject list, instead of 100%, I now had a score in the high 90s. I found these three practices listed in my mission and got through them to raise my score to 100%.

Of these three new practices, one of them, Circumference of parts of circles, is listed in both the May 2018 and June 2018 content update posts. (Perhaps the one in June is a correction or other update of the one in May.) The other two appear to have slipped through the cracks because they're not listed in either the May 2018 or June 2018 content update post. (If they were in the April 2018 content update or earlier, I would have caught them then.) They are:

Dividing negative numbers

Equivalent expressions with negative numbers and variables

I know you are very busy here, and things can get overlooked. But I thought I'd bring these to your attention. Perhaps they can be made part of the July 2018 content update.

Content Update: June 2018 (Humanities, Science, and more!)
