This is a Powerpoint activity for practicing choosing between ser and estar. Each student receives a pinch card with the letters A, B, C, and D. As you display the multiple choice questions, students pinch next to the letter of their choice and hold up their cards. This is an excellent formative assessment activity and a lot more engaging than a worksheet. After students have indicated their answers, the correct choice turns red so they can assess their own answers. Directions and a photocopiable pinch card are included in the Powerpoint.
