2.OA.B Add and Subtract within 20 2.
Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
Students will use M&M 's to determine how many members are coming to their family reunion and if there will be enough seats for everyone.
(Utah Education Network, 2014)
My favorite elementary grade was 2nd grade so I chose a lesson and activity for this grade off of UEN.ORG Website. The standard is that students should be able to add and subtract within 20 using mental strategies by the end of 2nd grade. Students should also know from memory all sums of two one-digit numbers.
I will start out the activity by reading The M&M Counting Book written by Barbara Barbieri McGrath. After the book has been read, I will place my students in pairs of two. I will than provide my students each a small cup of 40 M&M’s instructing them not to eat the candy, because we are using it for our Math lesson I will also provide my students each with a Math journal, sticky notes, and a copy of the M&M family reunion task:
The Family Reunion Task:
(Use your M&M’s to follow the five steps in this task)
1. I come from a large family of eight kids. Don’t forget to add mom and dad!
2. We are having a family reunion soon. Let’s figure out how many people will be there. My Aunt and Uncle have eight kids also. How many do we have now?
3. My Grandma and Grandpa are coming; they are bringing my Aunt Betty Lou.
4. Three of my cousins decided not to come. They are going to camp instead. How many are coming to the reunion now? (count your M&M’s and write your answer on the sticky note)
5. We’re setting up five tables that seat four peop...

...low me to assess whether or not they understand how to add, subtract, double, follow a story problem, and extend thru multiplication. Lastly, my students will be instructed to turn in their journals and if they haven’t already eaten them I will give my students permission to split the MNM’s and eat them.
When I am grading my student’s journals I will be looking to see if my students were able to meet the intended learning outcomes:
1. Students will make sense of problems and persevere in solving them MP1
2. Students will model with mathematics MP4
3. Students will reason abstractly and quantitatively MP3
4. Students will attend to precision MP6
This is a fun activity that I know I will enjoy teaching. I hope that my students are able to follow my instruction and be able to demonstrate on their own what they have learned and processed through this teaching style.

- Stan Gudder, an American mathematician once wrote, "The essence of Mathematics is not to make simple things complicated, but to make complicated things simple," A few year ago I would have strongly disagreed with Gudder’s statement. “Trigonometry, Geometry and Algebra. Oh No”. These Mathematics topics were my most feared enemies. They were not partial when punishing me. I knew within myself that if I wanted to conquer the IB math exam then I had to understand the esoteric, yet required content, of each class.... [tags: Mathematics, Question, Understanding, Help]

- Mathematics is a subject that many people fear and complain is too difficult to learn. The truth, however, is everyone is capable of learning mathematics, even complicated mathematics. They simply need to know the proper method of learning. Mathematics is different from other subjects. It is more than rote memorization. Developing learning skills is vital to learning mathematics. Study skills specific to the subject are required, as is developing problem solving skills and learning to properly deal with learning stresses.... [tags: Mathematics]

- Mathematics is possibly one of the most underappreciated sciences. It everywhere in our lives, mathematics runs our computers, flies our aircraft, and protects our information. But for such a major part of our lives, very few people can say that they know how it is done, how the RSA encryption protects their e-mail, or even that 21 squared is 441 without going into tedious mental calculations or reaching for their calculator. Contrary to popular belief, mathematics has a wide range of useful applications.... [tags: Mathematics]

- Tens go With Only Tens and Ones go With Only Ones: Common Core Standards for Mathematics is Beneficial for the Education System Imagine the math problem 24+68=?; this is a typical question that could possibly be given to students in second grade to solve. Below are two different methods for solving this problem. The first way is considered to be the more “traditional” way. In this method, one would use a two-column setup and then add. The first step is to add four and eight together to get twelve, so drop the two and carry the one.... [tags: Education, Mathematics, Teacher, School]

- Abstract. This paper presents a result of preliminary study conducted to measure Mathematics students' perceptions towards programming, and the activities of programming in general. Sample group were students who were currently pursuing their second year degree in Mathematics with Computer Graphics (MCG) programme, who took Computer Interface Programming (CIP) course during their first semester in their current academic year. The study was conducted after a realisation that the students were reluctant in attempting programming problems in their coursework that caused a large drop in their assessments marks....

- An ontological theorist generally begins his discussion with a preconceived notion of what kind of thing an object will turn out to be. Instead, we will here begin with a Thomassonian approach to the ontology of mathematics. First, let us consider what happens when we rst come to determine a mathematical proposition (which I will use synonymously with 'mathematical entitty'). A mathematician does not feel as though he creates mathematical theories. Pythagoras can hardly be thought to have created the claim that a2 + b2 = c2.... [tags: Mathematics]

- “Neuropsychology is a specialty that applies the principles of assessment and intervention based upon the scientific study of human behavior as it relates to normal and abnormal functioning of the central nervous system.” (The American Psychological Association) In more basic terms, the field of neuropsychology relies heavily on the study of the central nervous system combined with the study of the behavior of an individual. A type of psychology career, it involves using computational methods and mathematics, “particularly statistics, as a professional tool to quantify and analyze their scientific findings.” Neuropsychologists also work towards diagnosing any potential mental impairments...

- Correlation between 8th grade mathematic CMT scores and mathematic CAPT scores Introduction: Standardized testing, specifically “high-stakes testing”, has become a topic of debate for many years. “High-stakes testing” is associated with states that require successful performance on a standardized test for graduation, an “exit exam”. Is this the trend in public education. As an educator in Connecticut, should I expect “high-stakes testing” in the future. The State of Connecticut Legislature created a statue (Section 10-14n) that mandates statewide standardized testing for students in 4th, 6th, 8th and 10th grade....

- The Egyptians are one of the earliest known and most well documented people to inhabit the Earth. They were one of the first people to respond to practical needs within agriculture, business, and industry. Moreover, archaeological and historical artifacts suggest that the Egyptians were among the first to develop the study of mathematics. This paper will discuss the development of mathematics in ancient Egypt, focusing on the use of hieroglyphs, the decimal system, and hieratic writing and numerals to demonstrate that the Egyptians made notable contributions to modern day understandings of mathematics....
