Recap – adding 10 more or 10 less

Remember:

If the number of tens in total is 9 or less, the only

column that will change is the tens column.

If the total number of tens is over 9, 10 of the

tens will need to be regrouped into one hundred.

Recap – using the inequality signs

Practising Number – Example 1

Tuesday 30.6.20Recapping different ways to represent multiplication

Using arrays for multiplicationhttps://www.bbc.co.uk/teach/class-clips-video/maths-ks1--ks2-how-to-use-

arrays-to-multiply/zrks382

Arrays are a good way to represent multiples of a times table.

For example

1 x 5 = 5 2 x 5 = 10 3 x 5 = 15 4 x 5 = 20 5 x 5 = 25

Wednesday 1.7.20

Today, you are going to collect data about how many items around your house are red,

blue, green or yellow.

You will be recording your data in a tally chart before presenting it in a bar chart.

What Is A Tally Chart?

A tally chart is a table used for counting and comparing the numbers of multiple classes of a data set. The initial data is recorded using 'hashes' or tally marks, organised into

groups of five. This makes keeping track of the total number much easier as you can

simply count the groups of tally marks by five.

Bar charts – recap

What is a bar chart?

A bar chart (or graph) organises information into a graphic using bars of

different lengths. The length of these bars is proportional to the size of the

information they represent. For example, here is a vertical bar graph showing the

popularity of different colours among a group of children.

Favourite

colour

Number of

children

Red 8

Blue

Green 5

Yellow 9

Pink

Questions

1. How many children said pink was their favourite colour?

2. How many children said blue was their favourite colour?

3. How many more children said yellow was their favourite colour compared to green?

4. Which colour was the most popular?

5. Which colour was the least popular?

6. How many children we asked altogether?

Colour of item Number of

Green

Yellow

Over to you

You are going to explore around your

home/school for as many different items

you can find that are blue, red, yellow and

green.

You should record your data in a tally

chart and then try drawing a bar chart to

represent the data.

Watch this link for help with your bar

chart.

What your tally chart should look like

What your bar chart needs

• A horizontal axis (going across)

• A vertical axis (going up)

• The different colour of items

along the horizontal axis

• The number of items up the

vertical axis

Telling the TimeWe use clocks to help us to tell the time.

The small hand tells us what hour it is.

We call this the hour hand.

The big hand tells us how many minutes

past or to each hour it is. We call this the

minute hand.

When the minute hand points straight up to

the number 12, it is an o'clock time. This is

when a new hour starts.

When the minute hand points down to the

number 6, it is a half past time. This is

halfway to the next hour.

Telling the TimeA clock face is a circle.

In one hour, the minute hand travels all the way around the circle

and back to the beginning.

Telling the TimeA clock face is a circle.

In half an hour, the minute hand travels halfway around the circle.

Telling the Time

In quarter of an hour, the minute hand travels a quarter of the way around the circle.

Where do you think the minute hand would travel to in quarter of an hour??

Telling the Time

When the minute hand points to the

number 3, it is a quarter past time.

When the minute hand points to the

number 9, it is a quarter to time.

Telling the TimeCan you tell these times? Which clocks have a quarter past time and which clocks

have a quarter to time??

Remember, each interval on the clock

equals 5 minutes. 1 = 5 minutes, 2 =

After 6 (30 minutes past/half past

the hour), it then becomes minutes to

the next hour. For example 7 = 25

minutes to the next hour.
