Clearly explained, Crighton.You are a good teacher for others to learn from. Your voice sounds great and you go through each step at an easy to follow pace. I think you should share more examples of strategies for solving problems on your blog. You should also give examples with bigger numbers because you work well with them too.
Great job!I'm sure you would be able to teach younger children how to do place value!Amazing!Sincerely, Teva Tait.
