2018年10月8日 · UPDATED Digital Flippy Do! Now the Digital Flippy Do is easier to use with only a mouse. Clicking on the check boxes changes the binary number from a 0 to a 1 and back again. Also added a feature to help with creating binary notation from decimal notation numbers. The right panel of the Flippy Do allows a decimal number to be entered. As binary notation …

2019年9月20日 · I created a digital version of the Flippy Do that I can project for students to see. It also does the math for me in case I’m not paying enough attention to the addition while teaching. This updated version is easier to use with only a mouse. Clicking on the check boxes toggles 0 to 1. The reset button clears the number. This updated version includes a guide to …

2017年8月20日 · I made a new Flippy Do. This is my first year teaching CSP so I’m not sure if the Flippy Do needed an update, but this is what made sense for me. I wasn’t able to upload the file, here is a link to my Dropbox file.

2020年8月4日 · 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.

2020年8月25日 · Using the examples from the lesson, your students know they can any number they want on the Flippy Do. They should also recognize that they cannot represent all decimal numbers on the Flippy Do Pro. This isn’t possible because of how those numbers are stored in binary. On the Flippy Do Pro, you can represent .25, .50, and, .75.

2016年7月21日 · The Flippy Do is usually super helpful in teaching students binary numbers. If you come upon any other resources that you think work well with your students please share them here

2020年8月26日 · My District is going virtual for a while, so instead of making students manually create the Flippy Do at home, I reprogrammed the Flippy Do Pro in Lesson 5 for student use in Lesson 4.

2022年8月22日 · If we use the flippy do, we can see that we cannot represent decimal numbers. So we have to decide whether to round up or down. If the price of candy is $1.76, you can either represent it as $1 (round down) or $2 (round up). In binary this corresponds to 00000001 or 00000010. Who loses in either case? In the first case, the customer is paying less, so the shop …

2020年9月8日 · So, the wrap up discussion states: Ultimately, regardless of the size of our odometer or Flippy Do Pro, and how many bits we add to them, there’s going to be numbers that are too large, too small, or “in-between” the val…
