Identifying Triangles

Logo for Identifying Triangles
This Stand Alone Instructional Resource (StAIR) is designed as part of a 5th grade geometry unit.  The StAIR teaches students how to identify triangles by their angle sizes and side lengths.  In addition, the StAIR reviews how to identify triangles as congruent.  The StAIR ends with a self-correcting practice session.

This is a great resource for understanding and identifying triangles.  The use of quality graphics, and thoughtful design neither detracted from the learning process, nor confused the learner on what to do next.  The creator did a great job of setting clear objectives for the student, and giving them direction on how to navigate during the lesson.  I do think there was an opportunity missed to outline the State Guidelines in which this resource covers.  Not for the student, but so that any teacher, in state or out of state, can relate it to the guidelines I which they are held accountable.  The menu system provided excellent opportunity for the student to go back and review previous lessons, and allowed them to explore at their own path at their own pace.

The quiz was a great opportunity for the student to review what they have learned, and I really enjoyed how when giving an incorrect answer you provide instant feedback, and timely questions to get the student thinking about the correct answer.  I was a bit startled by the sound at first, and had I not had my speakers on, I wouldn’t have known there was any feedback at all.  That is something to consider when looking at UDL.  Just informing the student early that audio is present would likely be enough.  One last thing, and this is minor, on slide 7 you ask the student to point to the two obtuse angles.  The one that points to the envelope, is actually pointing to an area where there are 3 different angles, and your arrow appears to point to the flap of the envelope, not the outside corner of the envelope.  It took me a bit to realize I was looking at the wrong angle.

Overall, this is a great resource that I would suggest using in classrooms.  Both Virtually and Face-to-Face.

Wow! This is a great STAIR designed for 5th graders. Ruth, you took a difficult concept for students to learn by allowing them to visualize by using many examples, including real life examples and providing immediate feedback. Not only were they told right or wrong, you gave an explanation to why they got an answer wrong if and when they chose the wrong answer. I student taught in 5th grade and think that many of the students would have had no trouble going through this STAIR and getting something out of it. However, I do think that there may be that handful that would have had a hard time reading the content. I created my STAIR for 3rd grade and think I have the same problem with mine. I actually am going to be teaching 3rd and 4th grade this upcoming school year and may utilize the core of your presentation during a geometry unit. I think this would look great on the smartboard for the whole class to do together as well as individually.

I love the layout that you used with the menu homepage. The students knew exactly what they had to do and where they were at, at all times. The navigation was great, the sound was great, and the topic was great. You hit a lot of different learning styles but could be difficult for the lower math students to do on their own.

This is a great interactive tool for 5th graders.  It provides varied ways to interact as well as helps to illustrate key concepts.  I also like that there is a short assessment at the end that gives instant feedback for students.

The objective is clearly stated in on the first slide and the menu of options is easy to understand. I think this will be a great visual review for studets as they work independtly.

Technical Remarks:

I found some of the "special effects" did not work unless you hit the object in just the right spot. I also felt like it was hard to figure out how to get out of certain pages if you decided you did not want to practice that content anymore. I was also confused as to whether or not I got some of the answers right on the practice.  It was not self-correcting, nor did it make a sound to tell me it was wrong.

I thought it was a good topic to choose.  It is a topic where it is easy to have visual (and can be very helpful) and and you did a good job using them to explain the different angles and triangles.  I like the real world examples.

Technical Remarks:

I had a hard time navigating.  The navigating buttons didn't seem to work for me.  Also when I tried to do the quiz I didn't always know if the answer I gave was correct.  There was overlap in the writing on some of the pages.

This was a great Stair for teaching triangles. I'd like to use it this year in my Grade 3 class. I like the use of different teaching strategies such as students trying their own knowledge and also testing themselves without a wrong answer page that makes them feel unsuccessful. The parts where students read to understand and other parts where they learn by exploring what they think are both great for different learners. The UDL strategies having some visual movements and audio explanations also really benefit all types of learners. The colors were bright and inviting and there was a nice color theme throughout. The Stair was easy to navigate always having the "home" button as an option.

Technical Remarks:

Having so many sounds for right or wrong answers on the check your work pages was a bit confusing. Perhaps you could choose two for each so that students would know if they are making a correct selction, although, for the most part it was obvious. I also felt that students could easily skip parts as nothing stopped them from just going on. This may be a good thing or may allow some students to skp the whole thing.

Though this StAIR module is designed for 5th graders, I think some of the slides had too many words.  If I were to remember how I was as a fifth grader, I could picture myself getting overwhelmed when I see a ton of words.  (i.e. when reading about the definition of an acute angle…maybe make that into 2 slides).  However, I do think this StAIR executes its goal in explaining to the students the 3 different types of angels and 3 different  types of triangles by their angle size and side length, as well as reviewing congruency triangles.  This lesson provides lots of vital vocabulary that will be repeated throughout their math career.  This presentation hits and drills these terms, which is very beneficial to not only them, but the teacher so he/she won’t have to repeat themselves and will know that his/her students understand the word.  Being a math teacher myself, (I teach high school Algebra) I think understanding the vocabulary is one of the most important parts.  If you don’t understand the “lingo” in math, you will get nowhere.  It is a must! One thing that I really adored about this module is  the visuals. Having the students click on image that displayed examples of certain types of angles and listening  for  whether they got it correct by a ‘ding’ or incorrect by a ‘boom.’ I really enjoyed that  partake and I know fifth graders would really find it engaging and entertaining.  Plus, it reinforces the fact that math surrounds us and students can recognize these different types of angles anywhere they go.   

Technical Remarks:

On the technical aspect, I think this StAIR did a fine job with sounds.  But when it came to the practice portion I enjoyed the sound, but I also think there needs to be some sort of slide letting the students know if they got it correct or not.  The sounds were kind of hard to hear.  I also think some explanations could be good. Especially because it is for elementary students.  I think to spurse it up a video would be an excellent idea. Overall though, I think you did an excellent job and recommend you using this for your students this coming fall. Good job!
