Knowing a student’s name allows you to better connect with them. However, it is normal to learn some students’ names more quickly than others. Make an effort to learn students’ names to avoid unequal connections to your students. It can be helpful to video students saying their names so that you can practice the correct pronunciation. Checking that you are pronouncing their name correctly is an important way to show you value them as a person.
Example: "That's a great question ___!"
