Engage your students with this self checking decimals activity, where students look at a base ten model, and write the decimal, fraction, and written form. You get a self checking Google Sheets activity with 30 questions. Students will look at the base ten model and type their answers in the yellow boxes. The box changes green and a checkmark pops up to give IMMEDIATE feedback, so students know right away if they are correct. Incorrect answers will turn gray, prompting students to self correct.
