Apps used: Book creator, popplet lite Web resouces used: tot splash, glencoe manipulative site || Tot splash is free, but a free account only allows you to save one Totsplash. So if you were to want to embed the Totsplash indefinitely, you might not want to use this particular tool. If students were to use a screencasting tool to explain their totsplash and create a video, it could easily be made into a tutorial. ||
 * Possible Activity Types**:
 * **Title** || Number Modeling Mind Map ||
 * **Description** || Students will create a mind map to show how to model numbers in different ways. They will then begin a class number book to have a reference for numbers, and for students to reflect and comment on one another's models. ||
 * **Resources Needed** || Manipulatives, paper and pencil, iPads/iPods, computers
 * **Example** || media type="custom" key="24077500"[|Example TotSplash] ||
 * **Notes** || If students were to begin this process in earlier grades and use an electronic portfolio (using something like Google Docs or Evernote) they could continue to add to this as they move through the grades and add larger numbers.
