Have students work with a group to write a script and use iMovie or Flipgrid to explain a concept or strategy. Use Google Classroom or Seesaw to share the videos with the whole class or grade level for review.
Get students up and moving with a Task Card Review. Students can work individually or in pairs. Put your review questions/concepts/vocabulary on cards around the room. Students put their answers on a recording sheet or in a Google Form as they move to the different cards. Have more task cards than you have groups to avoid pile-ups and give clear expectations of procedures (show/explain work, stay with partner, etc.). Review answers in small groups or put the answers on QR codes for students to self-check. Check out Teachers Pay Teachers for some free premade task cards or make your own. Find more task card ideas here.
Use a Google Form with validation for students to enter answers to questions from a reading passage or group of math problems. They'll need to enter the correct answers in the correct order to move on. This 3 minute video explains the process.
