• Adding & Subtracting Fractions

    Posted by Bronwyn Chen on 11/5/2018

    Essential Questions:

    • How do adding and subtracting fractions help me in everyday life?
    • How can I join fractions with like denominators?
    • How can I separate fractions with like denominators?
    • How can I convert a fraction greater than 1 into a mixed number?
    • How can I add and subtract mixed numbers with like denominators?
    • How can I represent unit fractions in a line plot?
    • How can I add and subtract fractions found in a line plot?

    In this unit, students will be able to:

    • Join (compose) fractions of the same whole
    • Separate (decompose) fractions of the same whole in various ways (e.g.
    • Justify decompositions (e.g., by using a visual fraction model).
    • Convert a fraction greater than one (formerly referred to as an improper fraction) into a sum of a whole number and a number less than one
    • Add and subtract mixed numbers with like denominators using various strategies (e.g., replacing each number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction).
    • Solve word problems involving addition and subtraction of fractions with like denominators (e.g., by using visual
      fraction models and equations to represent the problem.

  • Common Denominators

    Posted by Bronwyn Chen on 11/1/2018

    Finding common denominators is very important when working with fractions. It helps us compare, add, and subtract fractions.

  • Comparing Fractions

    Posted by Bronwyn Chen on 10/29/2018

    Essential Questions:

    • How can fractions be compared?
    • How can models help me find equivalent fractions?
    • How can understanding numerators and denominators help me compare fractions?

    In this unit, students will be able to:

    • Use models to justify why fractions are equivalent
    • Generate equivalent frations by using models
    • Compare two fractions with different numberators and denominators using various strategies and recognize that comparisons are valid only when two fractions refer to the same whole.

    Vocabulary

    • Benchmark Fraction - a known reference fraction by which other fractions can be measured, e.g. 0, ½, ¼, ¾, 1
    • Common denominator - when two or more fractions have the same denominator
    • Denominator - bottom number in a fraction
    • Line plot - display of data on a number line, using an x or another mark to show frequency
    • Mixed number - number made up of a whole number and a fraction
    • Numerator - top number in a fraction
    • Equivalent Fractions – Two or more fractions that name the same amount.
    • Simplest Form – A fraction is in simplest form when the numerator and denominator have only 1 as a common factor.
    • Unit Fraction –  A fraction that has a numerator of 1. (such as ½ and ¼…etc)

  • Fraction Strips

    Posted by Bronwyn Chen on 10/23/2018

    Here is a printable fraction strip set for you to use at home.  Students will make their own set to use in class. This is a great tool to use when comparing fractions and identifying equivalent fractions.

     

    I also found a video that shows you how to make your own set of fractions strips to use at home. This is a fun way to develop a concrete understanding of fractions, and is a lot of fun to do. These are great to use with homework!
