Hi! I really appreciated the Flippy Do Pro that Code.org shared. I remixed and then revised to create a Flippy Do original app at https://studio.code.org/projects/applab/z6iQr137KHDvkIaz5UNCviWLVkkRnhyteDqWhWBJ56o
I added a text area so students could see the place value addends as a numerical expression.
I think I will first ask students to create physical flippy do from home (we’re online first 6 weeks) and then share the app.
