Introduction
Before you start the lesson, watch these Recap Videos with your student.
Recap with your student on Lesson 3. We used fractions to count in small steps along the number line.
Say:
- Today we are going to use fractions for something a bit different – to help share out amounts of objects – we’ll soon get the hang of this!
Show the 📄 12 Bananas (or real bananas if you have them). Explain that you are going to have half of the bananas each.
Say:
- Look how the fraction tells us what to do with the amount:
\frac{1}{2}. The 2 tells us to share the whole amount between two; the 1 tells us that we just want to know what is in one of those groups. That’s really helpful!
Invite your student to share the bananas between the two of you. Explain that we can also use number facts to split them as we know that half of 12 is 6 (because double 6 is 12).
Write: \frac{1}{2} of 12 = 6 and read this aloud together. 
Ask:
- How we could find of the bananas?
Write: \frac{1}{4} of 12 = ?
Agree that we could halve each half (like folding our paper rectangles in half and half again). Model doing this with the actual bananas, reminding your student that half of 6 is 3.
Demonstrate that \frac{1}{4} of 12 is 3 and complete the number sentence: \frac{1}{4} of 12 = 3.
Write: \frac{3}{4} of 12 = ?
Ask:
- How could we work this out? Let’s see what the fraction tells us to do.
\frac{3}{4}: the 4 tells us to share the whole amount between four; the 3 tells us that we want to know what is in three of those groups.
Together, agree that 3 quarters is 3 lots of 3 bananas, which is 9 (recall counting in 3s a few days ago to help with this).
Complete a number sentence: \frac{3}{4} of 12 = 9.
Finally, write: \frac{1}{3} of 12 = ?
Point out that this fraction says ‘one third’ and explain that a third tells us that we share the whole lot of bananas three ways.
Demonstrate this, making 3 sets of 4 bananas.
Complete the sentence: \frac{1}{3} of 12 = 4.
Show 📄 18 Bananas and model finding of this number.
Write: \frac{1}{3} of 18 = 6.
Main Activity
Ask your student to complete 📄 Fractions of amounts, using the strategies they have been learning. Encourage the use of counters to support their thinking.
