Week 10 - 11 Fractions

National curriculum content

Recognise, find, name and write fractions 1/3, ¼, 2/4 and ¾ of a length, shape, set of objects or quantity
Write simple fractions for example, ½ of 6 = 3 and recognise the equivalence of 2/4 and ½

Lesson objectives

What we want children to know

Explore making and recognising equal and unequal parts
Understand the concept of a whole as being one object or one quantity
Understand halving is splitting a whole into two equal parts
Introduce the language numerator and denominator
Extend knowledge of the whole and halves to recognising quarters of shapes, objects and quantities
Explain what each of the digits represents in a fractional notation
Understand of a third and three equal parts to find a third of a quantity
Understand the concept of a unit fraction by recognising it as one equal part of a whole
Understand that the denominator represents the number of parts that a shape or quantity is split into
Explore the equivalence of two quarters and one half of the same whole and understand they are the same
Begin to understand that fractions can be larger than one whole

What skills we want children to develop

Use knowledge to solve reasoning and problem solving questions such as:

What comes next?

5 ½, 6 ½, 7 ½, ….., …..

9 ½, 9, 8 ½, …., ….

What do you notice?

¼ of 4 = 1

¼ of 8 = 2

¼ of 12 = 3

Continue the pattern. What do you notice?

Odd one out

Which is the odd one out in this trio:

1/2 2/4 1/4

Why?

Mathematical talk

How many equal parts has the shape/object/length been split into?
What is the value of the whole? What is the value of the whole? What to do you notice?
How many quarters make a whole?
Can you shade 1/3 in a different way? How do you know that you have shaded a 1/3?
Why do we call them a unit fraction? Where can we see the unit?
Give me an example of a unit fraction and a non-unit fraction.
