The concept that I chose to explore is long division. Using the T-Gem method, I\u2019m hoping that integrating technology into the process will help students grasp the concept a little more easily. I will start with a bit of information about my class dynamics and what I have done before re-introducing these students to long division. In my math class, even though, I have a grade 7 class, I have only 8 students who are actually at a grade 7 level. This has caused our school to take a closer look at how we can best support our struggling learners, since the majority of them have not been tested and therefore, are not on an IEP. As teachers, we are not able to modify the curriculum, but rather, we must do our best to adapt it in a way that makes it accessible for these learners. As part of our PLC (professional learning community), we have created small groups that focus on mastering one or two concepts before moving on. Our goal is to try and fill some of the gaps that these students have so that they can feel a sense of success. At the beginning of the year, we administered an assessment to all the grade 7s so that we could see what concepts they had mastered and what concepts they needed to spend more time on. After working with our students and looking at this assessment, we discovered that there are quite a few students who do not understand how to do long division. <\/span><\/p>\n

I believe the first problem with long division is that many of the students do not have a solid understanding of basic division. With these intervention groups at my school, this is where we began our lessons. We started with having the students use manipulatives and moving (dividing) these manipulatives into groups. The students were shown some videos to help explain the process (BrainPop, Khan Academy). \u00a0We also related division to multiplication and showed how they are related (fact families, etc.). Phet<\/a> has a division simulation that helps show this relationship.<\/span> The students played \u201cgames,\u201d worked with partners, and used whiteboards to practice. Throughout the process, the teachers in the room observed the students and created formative assessments to make sure all of the students were grasping the concept successfully.<\/span><\/p>\n

Once this small group of students had a deeper understanding of what division is, they moved onto long division (this is the stage they are at now). One strategy that was used had the students using post-it notes to show the relationship between the numbers.\u00a0<\/span><\/p>\n

http:\/\/middleschoolocd.blogspot.ca\/2013\/09\/throwdown-linky-post-it-note-division.html<\/a> – Sorry, I couldn’t figure out how to get the visual in this document.<\/span><\/p>\n

This helped students see where the numbers go, the relationship between the numbers and the importance of lining up columns (this was an issue for many of these learners). One colour is used for the divisor and one for the dividend. The quotient and product are the same colour as the divisor so students can see that they are related. The difference is a third colour (yellow). I am trying to figure out how I can make this digital. Does anyone have any suggestions? Once students have mastered the PROCESS of long division (I find this takes longer than expected), there a tons of games, programs, videos and apps that help students practice this skill to create a solid understanding of how to complete long division questions. \u00a0<\/span><\/p>\n

One app that is great for getting students to show their understanding and thinking is Explain Everything. In the past, I have had students create a \u201chow to\u201d book so that they can teach others how to do long division. I find this to be a very helpful strategy.<\/span><\/p>\n

What strategies, resources or technology do you use to teach your students long division?<\/span><\/p>\n

On a side note, I absolutely loved the interactive Periodic Table in the Chemland Interactive website and wish I was able to use this during my chemistry course. Even though many of the concepts within this website are beyond what my grade 7 students are learning, some students might like to explore it if they have an interest in this subject area. In grade 7, students are learning a very basic level of chemistry, but this does not mean that some would not like to extend their learning and use Chemland to do that. They can click on any of the elements to learn more (density, boiling point, melting point, etc.). I also like that the descriptions are clear and written in a way that students can understand.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
