# Monday Must Reads: Volume 100

**Post Contents**hide

I can’t believe that this is the 100th volume of Monday Must Reads! It seems like just yesterday that I had the idea to start highlighting the awesome math ideas I saw being shared on twitter here on my blog.

Of course, it feels like just yesterday that I decided to even start writing a math teaching blog. This is currently year 11 in the classroom for me, and I started blogging while I was still studying education at university.

I hope you find an idea or two worth trying out in your own classroom from this 100th edition of Monday Must Reads!
