I call my warm-up Trabajo Del Timbre- it's what my Spanish teacher always referred to as 'Bell Work'. Students fill out side 1 during the first week and side 2 during the second week. At the end of the second week I'll collect the papers and choose two warm-ups to grade. (I go over the answers in class... so I'm really just checking for completion and participation). Students can lose their bellwork point if they are not participating during the activity!
This straightforward template is a visually appealing way to start class off right. I use it for 5 minute warm-ups that review previous material or introduce a new lesson.
I hope it works for you too!
