Equivalant Fractions with Unlike Denominators
In elementary math there are several concepts about fractions. One concept students in fourth grade will need to master is learning how to tell if fractions are equivalent with unlike denominators. There are a few prerequisite skills that are necessary in order for the students to understand this concept. The first thing students need to know is what fractions are. Fractions are a way of counting parts of a whole. Secondly, the students need to know how to identify parts of a fraction. The top number in a fraction is the numerator. The numerator is the number of parts in a whole (Eather). The bottom number in a fraction is the denominator. The denominator is the number of parts the whole is divided into (Eather). Lastly, the student will need to have a basic knowledge of their multiplication and division facts. This will help the students in deciding whether or not the fraction is indeed equivalent or not. The first step in teaching students about equivalent fractions is to have a whole class conversation using manipulatives or visual aides. I would start the lesson with an overhead projection or use of a mimeo board in order to show the students what equivalent fractions look like. I would start with two circles on the board, one divided into two pieces and one divided into four. You can show the students by coloring in one of the two pieces and two of the four pieces they are equivalent. Then write 1/2 and 2/4 side by side, in order to make 2/4 look like 1/2 you have to divide both sides by the same number. Both the numerator and the denominator in 2/4 are divisible by 2. Divide both the top and the bottom by 2 and then 2/4 becomes 1/2. Show the students again with a square. One divided into 4 sections and the other divided into 8 sections. The square with four sections color in one of the blocks to represent 1 of the 4 or 1/4 of the square is shaded. Have the students then figure out how many sections of the 8 need to be shaded to mirror or be equivalent to

    First of all the concepts in this course were based on the guidelines of the National Council of Teachers of Mathematics Standards for k-8 instruction. The council encourages teachers to encourage students by having fun while being taught for example fractions. Another way the concepts learned in this course are relevant to the characteristic of a professional mathematics teacher is the No Child Left behind Act. This course showed us ways to help the struggling child catch up with the class without making the child feel bad about…

    The numeracy curriculum gives pupils a solid grounding in all aspects of numeracy. In early years numeracy skills are developed practically in shape, pattern, counting, sorting and measuring. It is important that children and young people are avle to realise the important og maths and the impact it has on our everyday lives outside of school. The secondary provision related maths to a more real life situation, and as the children become more advanced more technical machanics are used.…

    Solving proportions

    • 868 Words
    • 4 Pages

    A comparison of two numbers is referred to as a ratio, similar to fractions that can be reduced to lowest terms and then converted into a ratio of integers. Ratios allow one to compare sizes of two quantities and unit measurements. Any statement expressing the equality of two ratios is known as a proportion, which is used in numerous formulas in today’s real world settings and applications. Using proportions is an effective way to find solutions by using the extreme means property or cross-multiplying. Extreme means property is simply the end result of the product of the extremes equaling the products of the means. Cross-multiplying is a short cut in proportions providing it is a faster way to solutions rather than multiplying each side of the rational expression equation by the LCD. Applications of rational expressions involving formulas include finding the equation of a line, distance, rate, time, uniform motion, and work problems. Proportions are used on a daily basis without even one realizing it by comparing measurements, unit pricing, driving distances, and calculating populations and wildlife on a daily basis to find a solution.…

    I currently teach a second grade class, but I have learned valuable information that I can use to help prepare my students mathematically for third grade. In second grade, my class completes tasks focusing on arrays and repeated addition toward the end of the school year. Creating equal groups is another concept taught more toward the end of the year. This course has provided insight on the importance making connections between mathematical operations: addition, subtraction, multiplication, and division. Another skill taught in second grade is decomposing numbers into hundreds, tens, and ones as students write numbers in expanded form or use base ten blocks to create a visual representation of a number. Students will continue to decompose numbers as they transition from addition and subtraction to multiplication and division (Beckman, 2014a, p.316). Completing assignments for grades higher than…
