Quick Error Analysis Practice

I am always in the process of changing up my lesson plans last minute. If my principal were to walk in my classroom on Wednesday, my agenda and activities would not match up with my lesson plans for the week. For example, I did not like the way my lesson was going with some of my classes during my quadrilaterals unit. I decided to rig something up last minute during my conference period and try it out with my remaining classes.

This activity was easy to make since all I had to do was solve the problems either correctly (truth) or incorrect (lie). Students had to separate the cards and justify their reasoning on the card stock. I thought that students would easily catch my errors but, students took their time and slowly examined each card.

I had a total of 7 "truths" and 5 "lies" and this threw some students for a loop because students automatically assumed that there would be an even amount of "truths" and "lies."






If you haven't already tried some error analysis practice, I highly recommend it! It is easy to create since you could use an anonymous student's work or you can write it out yourself.

Here are the blank cards that I used for this activity:

  2. Love this stuff! Thanks so much.
    And good for you for changing things up on the fly! You must be a great teacher because great teachers are skilled at gauging the needs of their kiddos and adapting in the moment.
