Lesson 1I can estimate, compare and calculate different measures, including money in pounds and pence

Tell a friend or partner, what each coin is worth.

What is each amount of money worth?

.

In £2 there is 200 pence.

In £1 there is 100 pence.

How much money is shown?

How much money is shown?

£2. 33p

If you were asked how many pence that is, you would need to remember that in £1 there is 100 pence.

So £2.33, would turn into 233p.

Because in £2 thereis 200 pence.

How much money is shown in pounds and pence, and just pence?

How much money is shown in pounds and pence, and just pence?

Pounds and pence- £1.57

Just pence- 157p

In the savings jar, there is pence.

Lesson 3I can identify acute and obtuse angles

AnglesThis lesson is all about different angles and their size.

Right angles, obtuse angles and acute angles.

An angle is

Right Angles

A right angle is an internal angle which is equal to 90°.

These are all right angles.

See that special symbol like a box in the corner? That says it is a right angle. The 90° is rarely written in. If we see the box in the corner, we are being told it is a right angle.

A right angle can be in any orientation or rotation as long as the internal angle is 90°.

Obtuse Angles

An Obtuse Angle is more than 90° but less than 180°.

These are all obtuse angles.

Acute Angles

An Acute Angle is less than 90° (think of acute as small and cute, acute angles are smaller than right angles).

These are all acute angles.

Key points:

•A right angle is 90 degrees. •Acute angles are smaller than a right angle. •Obtuse angles are bigger than right angles.

Lesson 6I can identify lines of symmetry in 2-D shapes

presented in different orientations

What is symmetry?Symmetry is when a shape or object has two completely identical sides that are either facing each other or are around an axis. A line of symmetry is the line that divides the two identical parts, each part being a mirror reflection of the other.

https://www.bbc.co.uk/bitesize/topics/zrhp34j/articles/z8t72p3

Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it, to show that both sides of the shape are exactly the same.

Which shape has the correct line of symmetry drawn?

Which shape has the correct line of symmetry drawn?

B

Which shape has the correct line of symmetry drawn?

Which shape has the correct line of symmetry drawn?

B

We can also find the lines of symmetry of shapes by folding a shape.

Using a piece of paper, draw a shape and see how many lines of symmetry it has.

Lesson 7I can complete a simple symmetric figure with

respect to a specific line of symmetry.

Recap - What is symmetry?Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it, to show that both sides of the shape are exactly the same.

A symmetrical pattern on a grid always has a horizontal and vertical line of symmetry.

If the line of symmetry was vertical and in the centre of the grid, where would the shaded square be?

Did you get it right?

Tell a partner or peer, which squares would needed to be shaded to make this shape symmetrical?

Did you get it right?

Lesson 8I can read, write and convert time between analogue and digital 12 and 24-hour clocks

Time

Do you know many seconds are in a minute?

Do you know many seconds are in a minute?

60 seconds!

Do you know many seconds are in 2 minutes? If 1 minute has 60 seconds?

Do you know many seconds are in 2 minutes? If 1 minute has 60 seconds?

120 seconds! (Just double 60)

Do you know many minutes are in 1 hour?

There are 60 minutes in 1 hour.

If there are 60 minutes in 1 hour, how many minutes are in half an hour?

There are 30 minutes in half an hour.

If there are 60 minutes in 1 hour, how many minutes are in 2 hours?

There are 120 minutes in 2 hours.

60 minutes (1 hour) X 2

When we tell the time, we can tell it using either digital or analogue.https://www.bbc.co.uk/bitesize/topics/zkfycdm/articles/zcrmqty

DigitalA digital clock displays the time using exact numbers and is set to 24-hour time.

E.g 12:34 or 18:26

Analogue Analogue clocks represents the time using a hand that spins around a dial and is set to 12-hour time.

E.g 7:00pm or 3:34pm

When we use the 24-hour clock (digital) clock. We need recognise whether the time we are telling is in the morning (AM) or afternoon/night (PM).

There are 24 hours in one day, but the day can be measured by splitting it into two halves. The first 12 hours of the day - from midnight to midday - are called AM, and the next twelve hours are called PM.

half past 2 in the morning half past 2 in the afternoon

The 24-Hour DayA day has 24 hours. A clock has 12 hours.This means each time will happen twice every day.

We must use a way to write these times differently. One way is to use a.m. and p.m.

2:30 a.m. 2:30 p.m.

p.m. (post meridiem – after noon)a.m. (ante meridiem – before noon)

The 24-Hour Clock

2:30 14:30

Another way is to use a 24-hour clock.This means the hours after 12 noon are converted to 13:00 to 23:00.

A 4-digit format is used. 2 digits for the hour, a colon (:) and 2 for the minutes.

This clock and table show the corresponding hours on a 24- hour clock.

Midnight is referred to as 00:00.

We would represent the time like this:

0:00 = 12:00 AM 12:00 = 12:00 PM

01:00 = 1:00 AM 13:00 = 1:00 PM

02:00 = 2:00 AM 14:00 = 2:00 PM

03:00 = 3:00 AM 15:00 = 3:00 PM

04:00 = 4:00 AM 16:00 = 4:00 PM

05:00 = 5:00 AM 17:00 = 5:00 PM

06:00 = 6:00 AM 18:00 = 6:00 PM

07:00 = 7:00 AM 19:00 = 7:00 PM

08:00 = 8:00 AM 20:00 = 8:00 PM

09:00 = 9:00 AM 21:00 = 9:00 PM

10:00 = 10:00 AM 22:00 = 10:00 PM

11:00 = 11:00 AM 23:00 = 11:00 PM

One trick to remember when trying to find the time using the 24hour clock is to add 2 on to the time you are finding-

1pm = 13:00 (1+2 = 3)

4pm = 16:00 (4+2=6)

Recap yesterday’s lesson

What time is the clock showing?

01:40 or if it was PM, 13:40. We would say this as 20 to 1.

Using the knowledge learned yesterday, with a partner or friend, convert these times from digital to analogue.
