A lot of students are afraid of algebra. Whenever I introduce algebra as a language and tell them that all we are doing is a change of language, I find them open and accepting to it. Then throughout the lesson I keep reminding them about the change of language. And voila! They get it.
The aspect of self-check is to move students towards independent learning and give the teacher’s correction work a break. Hope you and your class likes it!
Do leave a review and feedback if you use it. What is good and what is missing? How did the students fare in it?
