    I’m not 100% certain I used the Stages of Expertise accurately. I feel like the 3rd and 4th stages threw me off a little bit because they are so similar. I gave it a shot though. I focused on adding decimal numbers. I started with the idea that so many students usually just use their prior knowledge of adding whole numbers and don’t think to use place value and line up the decimals. In stage 5, I ended with students being able to use place value (maybe even mentally) and estimation to assess reasonableness. There might be some visual/manipulative representations that I could add in stages 2 or 3. I have had some difficulty using manipulatives, such as base ten blocks, with decimals. It always seems to confused the kids because they are used to using base ten blocks for whole numbers. I would welcome any feedback on these stages. This did help me really think through the stages that kids go through when learning a new concept.
