Adding Fractions
Aim • I can add fractions with the same denominator. Success Criteria • I can use a fraction bar to represent a fraction. • I can show two fractions on a fraction bar. • I can use a fraction bar to find the total of two fractions. • I can use a fraction number line to find the total of two fractions.

Fraction Wall On your fraction wall, show …
Fraction Wall On your fraction wall, colour in . On your fraction wall, mark another with lines. How many sixths have been coloured in altogether?
Fraction Wall On your fraction wall, colour in . On your fraction wall, mark another with lines. How many twelfths have been coloured in altogether?
Fraction Wall On your fraction wall, colour in . On your fraction wall, mark another with lines. On your fraction wall, mark another with dots. How many tenths have been coloured in altogether?
Fraction Bars How could this bar be used to show ? The bar needs to be split into 5 equal sections to represent fifths. 2 of the 5 sections need to be coloured in to represent the 2 fifths. Draw fraction bars to show each of these fractions:
Fraction Bars Draw a fraction bar to represent . Add so that your fraction bar shows + . so + = . Draw fraction bars to solve each of these calculations: or 1 What do you notice about the numerators and denominators when you add the fractions?
Beyond the Whole Solve these calculations:
Using Fraction Number Lines Fraction number lines can also be used to add fractions with the same denominator. 7 5 3 + 2 or 2 1 = 3 3 3 1 1 1 2 2 1 2 2 3 1 3 2 2 3 4 3 3 3 3 3 3 4 5 6 7 8 9 10 11 12 3 3 3 3 3 3 3 3 3
Using Fraction Number Lines Use the number line to solve this calculation. 11 3 + 4 6 + 1 or 3 2 = 3 3 3 3 1 1 1 2 2 1 2 2 3 1 3 2 2 3 4 3 3 3 3 3 3 4 5 6 7 8 9 10 11 12 3 3 3 3 3 3 3 3 3
