Fractions: Counting Equal Parts
Year 3 Mathematics Exploring how fractions represent equal parts of a whole Learning about numerators and denominators
WALT (We Are Learning To)
Identify and explain what the numerator and denominator are Explain how a fraction shows a quantity of equal parts Use area models to represent fractions Recognize that fractions represent parts of a whole
Activate Prior Knowledge: What Do You Remember?
Look at these shapes Which ones show equal parts? What do we call each equal part? Write your answer on your whiteboard
Understanding Fractions: The Rectangle Example
The whole is the complete rectangle The rectangle is split into 2 equal parts Each part is called 'one half' We write this as ½
Meet the Fraction Family: Numerator and Denominator
The bottom number is the DENOMINATOR It tells us how many equal parts the whole is divided into The top number is the NUMERATOR It tells us how many parts we are focusing on
Exploring Different Fractions
{"left":"One half (½): 1 part out of 2 equal parts\nOne third (⅓): 1 part out of 3 equal parts","right":"One quarter (¼): 1 part out of 4 equal parts\nOne fifth (⅕): 1 part out of 5 equal parts"}
Paper Folding Investigation
Work with your partner Fold your paper shapes into equal parts Label each part with the correct fraction Each shape must be folded differently
Critical Thinking: Same Fraction, Different Shapes
If this circle shows ½ and this triangle shows ½... Why do they look different? Are they still the same fraction? What makes them both 'one half'?
Examples and Non-Examples Challenge
Look at each shape carefully Decide: Equal parts or unequal parts? Complete the sentence explaining your thinking Remember: Fractions need EQUAL parts!
Reflection: What Have We Learned?
When we split a shape into equal parts, the denominator tells us how many equal parts the shape has been split into When we split a shape into equal parts, the numerator tells us how many of those equal parts we are focusing on Fractions help us describe parts of a whole The same fraction can look different in different shapes
