This series hasn't been published yet, but I found at least 3 typos (missing words, from what I can tell) in the first 3 paragraphs of the first column on page 11/11 as shown in preview section at the bottom of the page. Someone really needs to fine-tooth comb this before it gets sent out. I started reading on that page because I like to see what the meat of the resource has to say.
My Snipping Tool isn't working so I can't post examples, but anyone who reads English should be able to find the parts that don't make sense.
