• ## Essay On Rational Numbers

1023 Words  | 5 Pages

1.2.2 Rational numbers All the numbers that we use in our normal day-to-day activities are called Real Numbers. Real numbers are: Positive integers (1, 2, 3, 4, etc.) Fractions (1/2, 2/3, 1/4, etc). [The integers are really forms of fractions (1/1, 2/1, 3/1, etc.)] Negative numbers (-1, -3/4, etc.) Any numbers that can be written in the form a/b where a and b are whole numbers are called Rational Numbers. A rational number is a number that can be written as a ratio. That means it can be written

• ## Mixed Numbers And Subtracting Like And Unlike Denominators

467 Words  | 2 Pages

The third main idea is mixed numbers and adding and subtracting like and unlike denominators. When adding mixed numbered fractions with the same denominator you add the whole numbers like normal and add the fractions like normal remembering to keep the denominator. For example, 2 ⅔ + 1 ⅓ = 2 + 1 = 3 and then 2 +1 for the numerators keeping the denominator a 3 gives you 3 3/3 or 4. In the denominators are not the same you leave the whole number alone and adjust the fractions like you did before. For

• ## Key Ideas And Strategies Underpin The Use Of Fractions In Children

Fractions are often seen by teachers as difficult to teach in the classroom and in turn difficult for children to understand how and why we use them. Although this is the case, it should be noted that fractions underpin a child’s ability to develop proportional reasoning and helps promote further progress in future mathematical studies (Clarke, Roche & Mitchell, 2008). This highlights the need for a child to be proficient in fractions and for their teacher to also be able to progress a child’s learning

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. For example, 4/3 represents one full group and 1/3 of another
