What Are We Learning Today? L.O. To read and write Proper Fractions
Take 12 cubes • 12 cubes joined together makes one whole stick. • If I divide the stick into 2 equal parts I will have 2 halves. • ½ + ½ = 1 whole • If I now divide my stick into 4 equal parts I will have 4 quarters. • ¼ + ¼ + ¼ + ¼ = 1 whole
How many cubes were in each half? • How many cubes were in each quarter? • If I take just one quarter, how many quarters are left? • So I could write ¼ + ¾ = 1 • What would that be in cubes? • What number sentence could I write to show this? 3 + 9 = 12
10 Squares • How many squares are shaded? • How many squares are there altogether? • How can we write this as a fraction? • 3 10 • How many squares are not shaded?
What are these 2 numbers? 3 10 Numerator How many sections are shaded Denominator How many sections the whole has been divided into
How many squares are shaded? How many squares are there altogether? How can we write this as a fraction?
