ParticipantNovember 16, 2022 at 9:21 pm #2424The videos that resonated with me the most, since I (student) teach in a third grade classroom, were the videos on multiplication and division, since that’s essentially all we’ve been working on since the beginning of the school year. An “ah-ha” that I had with regards to multiplication was that multiplication learning really starts in second grade, when students are taught to partition a rectangle into no more than 5 rows/columns. This is interesting to me as I reflect on my own students’ knowledge when it came to arrays and finding the area of rectangles, both things we’ve covered this year, and I notice that there are a good chunk of my students who gravitate toward array when it comes to solving multiplication and division problems. A second “ah-ha” when it comes to multiplication and division is to let the context of the problem explain the equation. Lately, I’ve noticed that my students are able to look at an equation and come up with a strategy to solve, but when it comes to interpreting and tackling a word problem, they have a hard time creating a model and therefore an equation that aligns with the context of the problem. A final “ah-ha” that I had with regards to division, specifically, was that students should experience the difference between efficient and inefficient thinking. That way, they can recognize the need for a faster strategy for dividing with larger numbers and hopefully come up with some ways to mitigate that through their own exploration. A “wonder” I had with regards to third grade and the progression of multiplication and division, it how to get students to see the value of each and the difference between repeated subtraction strategies in which the groups are unknown and the fair share or partitioning strategy in which to objects are unknown. In my experience, too often the students get stuck on one of these and have a hard time differentiating which one makes the most sense in the context of the word problem they might be solving.

ParticipantNovember 18, 2022 at 10:47 am #2436In my experience working with different levels, the one I will focus on will be first grade, so the Early numbers and counting progression and the addition and subtraction progression are the areas I should go over and start working with students. I like to remember the content they were able to learn in kindergarten and connect it to the new knowledge. Applying new strategies for addition and subtraction shows me that students have different ways of solving and connecting content. There are students who need to draw pictures to find results, others use their fingers and others simply do a mental process. But if everyone likes to work with concrete material; grouping, putting or removing different objects, helps them to be able to visualize a result through the manipulation of different objects stimulates them to create a conceptual understanding of what is addition and subtraction.
By grouping different objects, students may be able to figure out that one number plus another equals another number plus another number. Sometimes children tend to think that, for example, 5 + 5 = 10, and that there is no other way to find the number 10. But when we show them another option, for example, 6 + 4 =10; they begin to understand that if we put different numbers together we can find the same results.
Now, when we start to use numbers greater than 10, we have the challenge that some students find it difficult to understand how to operate with them, so the decomposition of numbers is a strategy that allows them to simplify the largest number and be able to develop the exercises. more easily. -

ParticipantMarch 25, 2023 at 2:12 pm #3171All the videos resonated with me.It was good to see that the arrays and area models I stress in multiplication instruction. Also how important the understanding early numbers and counting are… hierarchal inclusion … did I stress that. Was very glad to se that use of ten fram3s were good practice for subtraction. After watching this, I understand why not to use “butterfly” but ugh…. Was the way I was taught and I have used it!
