To introduce the concept of order of operations to the students I would first write PEMDAS on the board which stands for Parentheses, Exponents, Multiplication, Division, Addition and Subtraction. I would put brackets around M and D, and A and S, to show that they are grouped together in the order of operations. “One misconception by students is that all multiplication should happen before all division because the multiplication comes before division in the acronym. In fact, multiplication and…

3. Focus Students: Description of Student A: Abby Prior Learning Abby’s prior knowledge of multiplication of fractions is limited because this is not introduced until the 4th grade. The student was able to get the first two problems on the pre-assessment correct which asked the students to find the missing value that would make the equation true when multiplying. The student does not understand the concept of unit fractions or the relationships between multiplying fractions and repeated…

Science defines the world that we live in. Anything from making a salad to constructing roller coasters requires the involvement of science. But we as humans have not created a way to completely eradicate the error of a measurement reading. Even with all of the advancements we have made in regard to technology and scientific resources, there is no way of getting an exact measurement. This is extremely apparent when looking at chemistry laboratories. When looking at a 50 mL graduated cylinder for…

Rationale: In creating the three SLO’s for this unit, the various needs of the students in this classroom were carefully considered. The three SLO’s are attainable and observable for these students in the timeframe provided for this unit. Accommodations will be provided to make the SLO attainable for each student in the class. Based on the students’ previous assessment data and their performance during previous units, these SLO’s can be achieved within this unit. The unit should take between…

Ryan- Hello and welcome to X+Y math news at 9:30!!!! Our top story - during a fight, 5 and 6 divided. The whole problem is negative 5/6k=12. to help find what k= our mathematicians have done the following steps. To solve this problem first they found the multiplicative inverse of -⅚ which is -6/5. next they changed 12 into a fraction which is 12/1 then finally they along with cross cancel. Finally they found the answer which is k=-72/5!!!!! As well as another problem has showed up in…

On Tuesday, October 20, 2015, I spent the day at Media Elementary School in the Rose Tree Media School District assisting 4th-grade teacher Mrs. Williamson. Mrs. Williamson is a teacher with 23 years of experience and she spent most her career with Media Elementary School. The school day for the students begins at 9:00 am and ends at 3:30 pm. I was supposed to report at 8:45 am as the teacher began preparing for the class few minutes before the students entered the classroom. I reached there at…

each person has a certain amount and that’s it. We call this fixed mindset, and, as you will see, students with this mindset worry about how much of this fixed intelligence they possess.”. When I started high school, my grades weren’t as well as in elementary school. When I learned about the different mindsets, I started to think about how my mindsets were back then and I realized that I have a fixed mindset. Even up to today, I’ve started to realize some of the actions a person with a fixed…

If people follow the instructions within the given chain letter, then numerous of wonderful things will happen to them; however, if they don’t they will be…

civilizations developed their ideas of mathematics and how they used mathematical concepts in their culture. Studying the evidence left behind by these people allow us to understand their number systems and their understanding and use of simple arithmetic concepts. Introduction Egyptians and Babylonians are groups of people who both developed mathematical concepts on their own societies. We can learn much from their ways of thinking by the evidence that was left from them. Egyptians are…

Subitizing is an important component to incorporate into an early childhood classroom. According to the Subitizing article, “Subitizing is “instantly seeing how many.” From a Latin word meaning suddenly, subitizing is the direct perceptual apprehension of the numerosity of a group” (p. 1). During the first and second half of the century, researchers believed in different idea on how subitizing impacts children. At first counting was believed to not imply a true understanding of number but that…
