3.M.OA.A.01
Model the process of multiplication using repeated addition, arrays, a number line, and groups of.
I chose this standard as it is one of the first I will be teaching in the 2017-18 school year. Because I started teaching full-time in December 2016, the first half of next school year will be foreign to me. There is a huge emphasis on learning multiplication in 3rd grade, so I want to be as prepared as possible.
At the end of last school year, my school purchased 60 Chromebooks for use in classrooms. While I didn't have a chance to utilize them last year, I have every intention of putting them to use in 2017-18. My pre-assessment was made using Kahoot!, and it is conceivable that my students could use the Chromebooks for the purpose of taking the pre-assessment. Depending on availability, each student may be able to have his or her own Chromebook or, if resources are limited, students could work in pairs sharing one Chromebook. The pre-assessment contains ten questions, which was intentional because it's easier for me to grade 😀. The first three questions are related to multiplication terminology and symbols that students were exposed to at the end of 2nd grade. This will help me assess whether or not students are familiar with key concepts. The next four questions take things up a notch by asking students to choose the repeated addition and array answers that match the pictures shown. I created these questions after looking at the final summative assessment 2nd graders at my school should have taken. Responses to these questions will help me gauge if they did learn these concepts. Depending on how far a particular 2nd grade class progressed, it is possible they may not have covered this in great length. Other 2nd grade classes may have reached or surpassed these concepts. The results of the final three questions will be very interesting to analyze. Those having a solid understanding of multiplication terminology, repeated addition, and arrays, may have little difficulty solving multiplication problems using groups of and a number line. Those with a weak understanding may have more difficulty. The pre-assessment will give me a very good idea of where students stand. The results are not meant to penalize or pigeonhole anyone but, rather, help me plan lessons to best suit the needs of all of my students. To view my pre-assessment, please click on this link. Kahoot! Pre-Assessment
Once pre-assessment results have been analyzed, students will be grouped according to their abilities for activities. Students with a low level of understanding will spend time reviewing important multiplication terminology, symbols, and the different strategies of multiplication. Using Chromebooks, students will watch a Khan Academy video that introduces multiplication and provides practice problems. The practice problems will serve as a formative assessment. Problems for these students will contain smaller factors and, as time progresses, factors will become greater. Math manipulatives will be utilized in the building of multiplication models. Finally, students will be given pre-lessons to prepare them for the following day. They will be asked to share what they've learned to help teach others, and to build trust and confidence.
Using Chromebooks, students with an intermediate level of understanding will watch a series of Khan Academy videos to reinforce what they already know, plus provide a refresher of concepts they may have forgotten. Practice problems will be completed by students, which will serve as a formative assessment. I envision students in this group, which will most likely be the largest group, working with a partner. As students gain understanding, they will move on to more challenging activities, like the "Problem of the Week," which is explained in more detail in my mind map (click to open). Students will also create their own multiplication word problems that group members will solve using the various models of multiplication.
Students with a high level of understanding will begin work on the "Problem of the Week," which is explained in more detail in the above mind map. Students will create their own multiplication word problems and equations that will be shared and solved by the rest of the class. These students will be given an opportunity to help struggling students via peer tutoring. Lastly, when ready, they will be introduced to division and its relationship to multiplicaton via Khan Academy videos and practice problems.
