Restructuring And Performing Operations With Fractions In The Classroom

1764 Words8 Pages

Truly understanding fractions and performing operations with fractions can often be difficult for many children and even adults. According to N. Krasa and S. Shunkwiler (2009), “Learning fractions is like stepping into the upside-down world beyond Alice’s looking glass. No wonder children are confused!” (p. 115). Discovering fractions in a way that enhances a student’s number sense is extremely important before the student begins operations with fractions. The Common Core State Standards for Mathematics in Oregon explain what a child in a certain grade must know concerning number sense and fractions. For example, standards 4.NF.1 and 4.NF.2 state that students in the fourth grade must be able to find, identify, and explain why two fractions …show more content…

The NCTM (2002) says that there are two phases of development when learning fractions: finding the meaning of fractions in regards to the link between division and divided quantities and discovering the strange properties of fractions (p. 7). Since developing a number sense of fractions is so important, teachers need to pick their students brains to decipher their thinking. According to the NCTM (2007), “Because getting the right answer is not always enough, teachers should implement classroom strategies to gather information on how students obtained the right answer (or wrong answer)” (p. 218). Problems that encourage students to explain their thinking can help the teacher discover how the students are processing the problem: either conceptually or procedurally. According to Krasa and Shunkwiler (2009), China’s education system implements the learning of fraction number sense in this specific order: the concept of fractions, decimals as special fractions with denominators of 10, decimal operations, multiples, factors, prime factors, improper fractions, mixed numbers, reducing fractions, common denominators, and finally, operations with fractions (p. 116). China’s approach is very logical and could be useful in the classroom. According to A. M. Klein (2003), the best learning environment for conceptual understanding is one that allows time for exploration, provides tools and models, and encourages children with a nurturing presence from the teacher (p.17). The authors of Helping children learn mathematics (2004) stress that teachers should “start with the simplest meaning and model” (p. 288). It is up to the teachers to create an environment where learning fractions is an exploration based on reasoning not a

Lesson 1, finding the area of different shapes, differed greatly in classifications assigned to the task outlined in the study. Consistent with all other lesson plans in the classifications A and E located in the lower-level demands, the students’ were assigned a task that required memorization of the formula used for calculating the area of a rectangle (p. 49). Unlike the previous nine lessons, the students task of “finding different ways to find the area of different rectangular-based shapes” (p. 50) involved problem-solving skills.

His parents could require him to work out five word problems, with a goal that he work out four out of five (80%) correctly before moving on to higher level problems. As his math and applied problem fluency increases, the problems could be harder and the number of problems per session can be increased (7, 8, 9, 10 word problems per sheet). The focus can still be on 80% of the problems correct even as the difficulty and quantity of problems increase. This is based on “Standard - CC.2.1.4.B.2 Using place value understanding and properties of operations to perform multi-digit arithmetic” and “Standard - CC.2.1.5.B.2 extending an understanding of operations with whole numbers to perform operations including

During the last 50 hours, Ashley has been working on learning the division facts and has learned to multiply 2 and 3 digit numbers by 1 digit with all combinations of regrouping. In both these areas she has built fluency. She moves through problems quickly with very few errors. The third grade standard is to be able to multiply and divide within 100. Ashley is currently multiplying within 1000.

o Mental math: 20 ÷ 2 (10) Step 2: Solve • Have students solve the division problem using long division for the 1st problem and mental math for the second problem on their chalkboards. Remind students to show all their work for the first problem. • Walk around and check for understanding, ask guiding questions to help students who might need further assistance. • When students have solved the problem, ask students to raise their chalk boards to show you their answers. If correct, students may erase their work.

“One thing is certain: The human brain has serious problems with calculations. Nothing in its evolution prepared it for the task of memorizing dozens of multiplication facts or for carrying out the multistep operations required for two-digit subtraction.” (Sousa, 2015, p. 35). It is amazing the things that our brain can do and how our brain adapt to perform these kind of calculations. As teachers, we need to take into account that our brain is not ready for calculations, but it can recognize patterns.

He begins by stating that many people assume that Asian students have an “innate proclivity for math” because Asian countries “have substantially outperformed their Western counterparts” in international mathematic exams (230). But in reality, Gladwell proved that Asian countries actually have a cultural advantage in the subject due to their number system. Most numbers in Chinese “can be uttered in less than a quarter of a second” while English numbers take a third. This difference allows Chinese children to memorize and count at an earlier age, leaving Western children a year behind at age five. Similarly, Gladwell cited Chinese culture of hardwork growing rice paddies as a reason for mathematic success.

Aly seems to have multiple misconceptions about fractions during the video. One misconception she has is that a whole number is bigger than an improper fraction. When comparing 1 and 4/3 she identified 1 as the bigger number. When Aly was asked for her reasoning she said, "1 group of one number". Aly here doesn't have the understanding that an improper fraction can be turned to a mix number which consist of a whole number and a fraction.

It also addresses procedural fluency in that students, with conceptual understanding, will “perform operations,” building on the arithmetic skills they already have with their procedural fluency of exponent laws. Students will use problem-solving skills when they must decipher context to find relevant information in order to perform operations in scientific notation. The lesson 1 learning objective, “given a very large or small number, scholars will be able to write an expression equal to it using a power of 10 and identify whether or not a number is written in scientific notation,” will address conceptual understanding and mathematical reasoning as students make a connection between powers of 10 and their prior knowledge of place value, understanding that the power of 10 has meaning. Students must then use mathematical reasoning to judge how large or small a power of 10 is.
