Fractions FRACTIONS Learning Outcome I can… * explain what a fraction is. * explain what the denominator of a fraction is and find the denominator of a fraction. * explain what the numerator of a fraction is and find the numerator of a fraction. * write a fraction. WHAT IS A FRACTION? ▪ When an object is divided into a number of equal parts then each part is called a fraction numerator 2 denominator 3 Denominator The denominator says how many equal parts in the whole object 1 2 equal parts 2 How many equal parts are there in this shape? What is the denominator of this fraction? 1 How many equal parts are there in this shape? What is the denominator of this fraction? 1 4 Find the denominators of these fractions 1 1 1 1 Find the denominators of these fractions 1 1 4 3 1 1 2 8 Draw what you think these fractions look like. 1 1 1 1 6 3 4 10 Draw what you think these fractions look like. 1 1 6 4 1 1 3 10 So, the denominator (on the bottom of a fraction) tells us… 1 Denominator 2 How many there are in the whole object numerator The numerator says how many parts in the fraction 1 part is 1 coloured in 2 How many equal parts are coloured in in this shape? What is the numerator of this fraction? 4 How many equal parts are coloured in in this shape? What is the numerator of this fraction? 3 4 Find the numerator for these fractions 4 3 8 8 Find the numerator for these fractions 3 2 4 3 1 5 8 8 Draw what you think these fractions look like. 2 1 3 9 6 3 4 10 Draw what you think these fractions look like. 2 3 6 4 1 9 3 10 So, the number on the top of a fraction tells us… numerator 1 2 How many we are counting or how many we have shaded. Find the fraction of these shapes Find the fraction of these shapes 4 1 6 4 2 6 3 9
