Fraction Addition and Subtraction with Like Denominators By Mr. Bales
Objective Be the end of the lesson, you will be able to add and subtract fractions. Standard 3NS3.2 - Students will add and subtract simple fractions(e.g., determine that 1/8 + 3/8 is the same as 1/2.)
Introduce Using the pattern blocks in the middle of your desk, answer the following questions: If the hexagon is the whole, what fraction is one trapezoid? One rhombus? Three triangles? Two trapezoids? Two rhombus?
Let’s Practice!! Using the pattern blocks, let’s see if we can add fractions. The hexagon is the whole: Show 2/6 and 1/6 How much of the hexagon do you have if you added them both together? 1/6 + 3/6 5/6 + 1/6 Using the rhombus show 1/3 + 1/3 How much of the hexagon do you have if you added them both together? 2/3 + 1/3
Like Fractions The fractions 2/6 and 1/6 have the same denominators. They are like fractions. You can add like fractions. To add fractions with like denominators, add the numerators and keep the same denominator.
Let’s practice a few together!! Yeah!!
Let Me Break It Down If the denominators are the same, then simple add the numerators and put that over the same denominator Same denominator Simply, just add =3 Place 3 over the denominator Let’S hear from Mrs. Benson!! Game!!
Bales Bucks Add/subtract and then reduce to simplest form!! 4/7 + 2/7 3/8 + 2/8 1/3 + 1/3 4/9 + 5/9 8/12 - 3/12 9/20 - 7/20 1/6 + 3/6 7/23 + 9/23 8/ /100 50/ /200 16/17 - 4/17 28/ /19
Thanks for Watching!! Hope You Learned A Lot!!!
