The children should be able to represent, read and interpret data on pictograms and block graphs.
You can download a pdf of the work below if you would like to print it out. Just click here.
Monday: Mental Maths: What number comes next after each of the following numbers? 65 ? 29 ? 70 ? 99 ? 109 ? 44 ? 132 ?
1. Let us look back at a few things you learned last year. Do you remember what data means? The word data means facts or a collection of information. Sometimes we want to show data on a chart or a table. This makes it easier for us to read and interpret or understand.
We are going to look at pictograms and block graphs. In both pictograms and block graphs the data is shown in columns or in rows.
In the chart above there are 5 columns. They are A, B, C, D and E. They go down.
In the chart below there are 5 rows. They go across.
Remember: columns go down and rows go across.
2. A pictogram is a chart or a graph which uses pictures to represent data. Let’s have a look. Here is a pictogram of the games the second class children like to play on the yard. I want you to look carefully and answer some questions.
Which game is the most popular?
Which game is the least popular?
How many children like football best? How many children like skipping/ hula hoops/yo-yos/marbles best?
How many more children prefer football to yo-yos?
How many more children prefer yo-yos to hula hoops?
Which 2 games are preferred by the same number of children?
How many children altogether like skipping and hula hoops?
How many children altogether like football and marbles?
How many children are there in this second class?
Which of these games would you like to play on the yard?
Is the data shown in columns or in rows?
By answering all those questions you are reading and interpreting data.
2. Do page 1 in your Problem Solving Maths Booklet. Write the sums in your Rough Work column.
3. Go to Planet Maths 2nd Class Resources. Click on Strand and then click on data. Do the Data Squares activity.
Tuesday: Mental Maths: What number comes just before each of the following numbers? 77 ? 50 ? 110 ? 98 ? 33 ? 81 ? 112 ?
1. Yesterday you looked at data on a pictogram. You were able to read and interpret the data. Today you are going to represent data on a pictogram.
In your 2D shapes box you have 5 circles, 7 squares, 2 ovals, 3 rectangles and 6 triangles. Can you represent that data on a chart?
Draw the correct number of shapes in each column. This is how you represent data.
2. The teacher asked all the children in Second Class what was their favourite treat. The picture graph below shows each child’s favourite treat.
How many children like crisps best?
How many children like cupcakes/ popcorn/ chocolate/ice-pops best?
Which was the most popular treat?
Which was the least popular treat?
How many more children preferred cupcakes to popcorn?
How many more children preferred ice-pops to crisps?
How many more children preferred cupcakes to chocolate?
How many children were in the class altogether?
3. Do page 2 in your Problem Solving Maths Booklet. Write the sums in your Rough Work column.
Wednesday: Mental Maths: Start counting at 63 and count up to 90. Start counting at 38 and count up to 62. Start counting at 84 and count up to 116. Start counting at 96 and count up to 127. Start counting at 101 and count up to 132.
1. As well as showing data on pictograms we can show data on block graphs. In block graphs instead of drawing a picture of each item, you can colour 1 block or 1 bar to represent each item or each preference. This is easier and quicker than putting in pictures or drawing pictures. Let’s have a look.
When I asked all the children in Second Class to name their favourite Premier League team, this is what they said. 5 children liked Manchester United best. 2 children preferred Spurs. 6 children preferred Liverpool. 4 children preferred Arsenal. 3 children liked Chelsea best.
Block graph A above shows the data about the children’s favourite football teams.
a. Can you tell from the block graph which is the favourite football team? Was it easy to see which one is the favourite team? b. Which of the 5 teams is the least favourite? Did it take you long to figure that out? c. How many children are in this Second Class? d. How many more children prefer Liverpool to Spurs? e. How many fewer children prefer Chelsea to Liverpool? f. Do you have a favourite team? If so, which is your favourite?
Block graph A is a vertical graph. It shows the data in columns. We can also show the data on a horizontal graph. It shows the data in rows. Block graph B below is a horizontal graph. It shows the data in rows.
Both block graph A and block graph B represent the exact same data. Can you see that they both show the same information? Sometimes we show the data in columns and sometimes we show the data in rows.
2. Do page 3 in your Problem Solving Maths Booklet. Write the sums in your Rough Work column. 3. Go to Planet Maths 2nd Class Resources. Click on Strand and then click on data. Do the Alien Sports Day activity.
Thursday: Mental Maths: Start counting at 53 and count back to 30. Start counting at 76 and count back to 55. Start counting at 92 and count back to 69. Start counting at 100 and count back to 87. Start counting at 119 and count back to 99.
1. Here is another block graph for you to interpret. The children in Second Class all picked their favourite zoo animal.
Which is the most popular animal?
Which animal is the least popular?
How many children said that the elephant is their favourite animal?
How many children said that the tiger is their favourite animal?
How many children are in the class altogether?
2. Here is some change Max found in his schoolbag. Would you be able to show the data on a block graph? Show how many 1c coins he found, how many 2c, 5c, 10c and 20c coins. Colour one block for each coin in the appropriate column.
How many coins in the 1c column?
How many coins in the 5c column?
Which column has the fewest coins?
How much money is there altogether in the 2c column?
How much money is there altogether in the 5c column?
How much money is there altogether in the 10c column?
How much money does Max have altogether?
3. Do page 4 in your Problem Solving Maths Booklet. Write the sums in your Rough Work column.
Friday: Mental Maths: What number comes after? 49, 87, 105, 111, 166, 170, 129? What number comes before? 71, 38, 101, 150, 188, 193, 141
1. Let’s do a recap on what you have learned so far. Do you know what the word data means? Do you know the difference between a pictogram and a block graph? Do you know what a column and a row are? Do you know the difference between a horizontal graph and a vertical graph?
2. Could you fill in this graph with your family?
Ask everyone in your house what was their favourite subject in school. If there aren’t enough people in your house, you could ask your granny, grandad, cousins, aunties and uncles too when you talk to them on the phone. Colour one block for everyone’s favourite subject.
3. Do page 5 in your Problem Solving Maths Booklet. Write the sums in your Rough Work column.
4. Go to Planet Maths 2nd Class Resources. Click on Strand and then click on data. Do Desmond’s Necklace activity.
Your teacher has more Mental Maths, Word Problems and lots of other activities on your class page, so if you want to do more, you can try th em too. Do whatever you can.
