Strategies to Solve Addition and Subtraction Essay

In order to improve my instructional practices, I analyzed instructional data from district math diagnostic and proficiency assessments. The most recent assessment assessed student’s abilities to count, add and subtract, and their understanding of place value. My students scored below not only the other first grade students at the school, but also all first grade students in the district. 81.6% of my students could count, read, and write numbers to 120. This was an improvement from their diagnostic assessment. However, only 66.7% could relate counting to addition and subtraction, and only 45% demonstrated understanding of place value in two digit numbers.

The aims and importance of learning provision for numeracy development are to ensure all students understand that maths is a vital part of everyday life and will continue to be used throughout their life. Primary schools will teach students to learn various methods and techniques to be able to reach the correct answer. The end goal means more students will be able to solve a mathematical problem, independently, using a method that suits them. They can then develop their learning to improve their knowledge and apply it to real life situations; such as counting in groups of numbers such as 5’s or 10’s, which in turn can be applied when paying for

The math concepts taught in this lesson are teaching the students how to use certain math formulas, and practice addition and multiplication. It is beneficial for students to know what tools to use for capturing and displaying information that is important to them (Davis, 2011). The science concepts taught in this

The pre-assessment used to establish students’ baseline knowledge and skills for this lesson is first to watch the video https://www.youtube.com/watch?v=9Z2gpbYiEXo. After the video engages the students to bring back prior knowledge, they will be given a white board. The students will work out a subtraction problem on the board for me to see what they already understand about solving subtraction word problems. I will use the data to know what parts of the instruction on how to solve subtraction word problems need to be more emphasized to the students.

1 Using addition and substation within 20 to solve word problems involving situations of adding, taking from putting together, taking apart and comparing, with unknowns in all positions, e.g., by using objects, drawing, and equation with a symbol for unknown number to represent the problem.

Jazmine was introduced to two digit addition. My first lesson focused on drawing tens and ones to solve two digit addition. This strategy would provide Jazmine with the visuals she needs to solve the problem. First, I did a quick review on how to draw tens and ones to represent a number. She was given three examples ranging from easy to hard. Jazmine showed no signs of difficulty and was able to complete the task. Then, I demonstrated how to use the drawings to add two digit numbers. I explained how she must draw the picture for each addend. Then, I explained that she must count the tens first and then the ones. She smiled and said “that's easy”. We went through a couple of problems together and Jazmine displayed that she understood the strategy of drawing tens and ones to solve two digit

[As a result of the step by step direction in the reengagement lesson, I want students to be able fully grasp the concept of addition; and how the knowledge of addition can be used to provide answers to expressions that require the decomposition of numbers totaling 8, 9, 10. The state standard that I am addressing in this reengagement lesson is 1.OA.1 Common Core State standards; use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together,

At: Students at grade level will be expected to complete 6-8 of the three digit addition problems during the provided activity time. At grade level students will be expected to use at least one of the provided strategies to solve for the sum. Students who finish early will be asked to draw a picture or write and explanation of the strategy/strategies they used to find the sum. The teacher will direct students who are early finishers to complete this task individually. Slow finishes will be provided with three, two-digit addition problems

As a student, I always enjoyed math. In high school I took all of the offered math classes, including Calculus. The first math class I took in college was a breeze, and I thought that this one would be no different. What could I learn about elementary school math that I did not already know? Contrary to my expectation, the first day of class, I learned things about math that had never been brought to my attention. This paper will discuss what I have learned about subtraction, about students, about the Common Core State Standards, and how my concept map has changed since my first draft.

Bridge to Prior Knowledge: Recite the numbers 0-10 from number chart as a class. Than have each student count independently on the number chart or tell you how many counting manipulatives they have.

In Section D, Daniel demonstrated a primary understanding of the multiplication and division concepts. Daniel can count group items by ones. He also counts one by one to find the solution for involving multiple groups when all objects are modeled. Daniel was able to use different strategies to count the cars in the boxes as he said, “I can count them by twos because there are two cars in each box,”

First, I disagree with the statement made in the last paragraph that said “one could easily argue that this exchange simply represented Danny’s misunderstanding of the task, we believe that if we look at this response as further explication of his conceptions of combining tasks and place value, we gain a more textured and multidimensional view of Danny’s understanding of number concepts” (p. 53). The student did not understand the task which caused confusion from the beginning. The student thought this was a place value task instead of a missing-addend task. The student asked for clarification over and over and then asked the teacher for confirmation when he said there was eleven chips. He did not receive confirmation so he changes his answer

The author explains how many students, especially those in the focused-upon second grade class, have difficulty explaining their “mathematical thinking process”. While they may provide correct answers using memorized calculations, they are unable to demonstrate their conceptual understandings or explain how they achieved the right results. As stated by the researcher, “it is important for students to be able to demonstrate their mathematical thinking as well as their method of solving a problem” (Kostos & Shin, 2010, p.223).

Teacher Instructions: During large group math, students will act out addition problems at “the bus stop”. Students will take turns being the actors, get a number and sit on the bus with another number. Class will solve the problem of how many the numbers will make before getting off the bus. Next student will write the new number (answer) on the dry erase board.

The lack of adopted curriculum also means that most, if not all, teachers are supplementing both materials and instructional routines. These students need to pass the state-mandated Smarter Balanced Assessment (SBA) which requires completion of a problem-solving performance task. Students need to know which operation(s) to use (addition, subtraction, multiplication, and/or division) and how to apply them appropriately. This problem has
