Latin American Subtraction Algorithm The Latin American subtraction algorithm is based on the fact that the difference between the two numbers does not change while adding the same amount to the minuend and subtrahend (Indiana University Southeast, n.d.). This algorithm appears to be one that requires precision to detail as it is different from the traditional subtraction algorithm the majority of students have been taught. Regardless of teacher preference, providing students with various strategies allows them to experience the diversity in problem

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 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.

## The Common Core State Standards Essay

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.

Multiplication by ten gives students opportunity to explore larger numbers, and can also be extended on(Reys et al. ch. 11.4). In addition, multiples of 10 give students the knowledge that all digits move left one place and an additional place hundreths. This concept can be used to introduce the decimal place which is also moving place each time something is multiplied by tens. Exposing students to a range of examples which displays patterns that occur when multiplying by tens and hundreths will generate meaning of digits moving place (Reys et al., ch. 11.4).
