Tuesday 5th May: Year 5 – Decimals up to 2 dp (Decimal place)

When we say the phrase ‘decimal place’ (dp) we are looking at the digits that appears in the place value chart after the decimal point.

if we are looking at ‘2 decimal places’ this means decimals that appear in the ‘tenths’ and the ‘hundredths’ columns.

    • Dexter is wrong you can have many ways to partition 0.62 like you could do

      0.32=+0.30
      0.02+0.60
      0.20+0.32
      0.01+0.61
      0.10+0.52
      0.42+0.20
      0.60+0.2

  1. 1) there are 0 ones there are 2 tens and 3 hundreds the number is 0.23

  6. 4.234 is a decimal up to 2 Decimal points because the decimals are placed in the tenths and hundredths There is an extra column but the decimal point is still placed in the tenths and hundredths columns.

    Im going to finish the writing part in my book so i can email it. :}

    • Starter Challenge-
      Is 4.234 a decimal up to 2dp?
      4.234 is not a decimal up to 2dp because it has 3 digits that are below the decimal point. Instead this is a decimal up to 3dp.

    Mrs i didn’t know how number 3 or 1

    • Sarina “is 4.234” a 2dp? You are correct it does have a tenths and hundredths column. But look, it has another digit, ‘4’, which would go into the ‘thousandths’ column – this would make it 3dp!

    • Well done for trying your best Sarina. Check your answer for number 1 again it is not quite right. Draw a grid like I have shown you in class. Example 2.458 would have a ones column then a decimal point then a tenths column and a hundreths column. Draw it out and put the 2.458 under those columns in the correct places. Then try question number 1 again. Let me know if this helped you get the right answer.

    • Well done Sarina.

      For question 1) think about how many counters are in each column – so in the ones there are 0… so the decimal is 0. (? ?) – Can you finish the last two columns? Count the counters in each column.

      3) What is the value of 4 in each column, so put each decimal into the place value chart. Is the 4 in the ones, tenths, etc? It will be different for each number.

      Thank you!

  8. Starter challenge:
    Is 4.234 a decimal up to 2dp? Explain how you know
    This is not a 2dp because it is over the hundreths and does not fit o the grid. It is actually a 3dp. We would need a thousandths.
    I have done the other activities in my book.

  10. 4.234 is is not a number with 2dp it has 3dp because it has 3 numbers beyond the decimal point,2,3 and 4 and the sentence says “up to” so maximum 2dp and if I’m correct,2 is smaller than 3. I’ve done the rest but i couldn’t do the challenges of religious priorities

  11. There are 0 ones, 2 tenths, and 3 hundreths. The number is 0.23. 3 0.62 = 0.5 add 0 .12
    0.62= 0.4 add 0. 22
    0.62= 0.3 add 0.32.
    234 isn’t a decimal up to 2 dp . The reason why that is because if it was a decimal up to 2 dp it would be part of tenths and the hundredths column but this is a 3 dp decimal because it is both is in the tenths , hundredths and thousandths column. There are 0 ones, 5 tenths and 6 hundredths.
    0.08
    There are 0 ones, 0 tenths and 8 hundredths.
    1.48
    There are 1 ones, 4 tenths and 8 hundredths.
    2.07
    There are 2 ones, 0 tenths and 7 hundredths.
    14.8
    The 4 in this decimal point number is in
    the ones column.
    13.74
    The 4 in this decimal point number is in the hundredths hundredths column.
    8.04
    The 4 in this decimal point number is in the hundredths column.
    42.03
    The 4 in this decimal point number is in the tens column.
    106.48
    The 4 in this decimal point number is in the tenths column.

  12. Decimal up to 2d.p

    Starter challenge

    No, 4.234 is not a decimal place of 2d.p, this is because the number 4 on the right hand side of the sum is in the column that represent the thousandth.

    Decimal up to 2d.p

    1) 0.23 – there are 0 ones, 2 tenths and 3 hundredths. The number is 0.23

    2)
    a – 0.56 – there are 0 ones, 5 tenths and 6 hundredths.
    b – 0.08 – there are 0 ones, 0 tenths and 8 hundredths.
    c – 1.48 – there are 1 ones, 4 tenths and 8 hundredths.
    d – 2.07 – there are 2 ones, 0 tenths and 7 hundredths.

    3
    a – 14.8 the value of 4 is ones.
    b – 13.74 the value of 4 is hundredth.
    c – 8.04 the value of 4 is hundredth.
    d – 42.03 the value of 4 is tens
    e – 106.48 the value of 4 is tenth.
    f – 176.4 the value of 4 is tenth.

    4
    a – the number that has 5 in the tenth is 0.53.
    b – 0.53, 1.53, 7.53.

    5
    a – 0.64 = 0.6 + 0.04
    b – 0.53 = 0.5 + 0.03
    c – 0.3 + 0.05 = 0.35
    d – 0.06 + 0.8 = 0.86

    6 – here is couple of ways to get 0.73.

    0.07 + 0.3 = 0.73
    0.7 + 0.03 = 0.73

    7
    a – I think it could be 0.35.
    b – 0.31, 0.32, 0.33
    c – my number has 3 digits, is greater 1, but less than 5, but has 3 tenths and 4 hundredth.

    8
    0.56 – 5 tenths and 6 hundredths.
    60.05 – 6 tens and 5 hundredths.
    5.56 – 5 ones, 5 tenths and 6 hundredths.
    5.65 – 5 ones, 6 tenths and 5 hundredths.

    9
    a – no, she can make 5.20 the largest number.
    b – yes, she can make 0.25 the smallest number.
    c – 0.52, 5.20, 2.05, 0.25, 5.02 and 2.50

    Teddy number is 40.46
    Amir number is 46.2
    Rosie number is 46.02
    Eva number is 2.64

  13. 4.234 is a decimal up to 2dp because it has the number 2 after the decimal point I figured the answer because it has dp after it

    challenge 2
    eva 46.02
    amir 46.2
    rosie 2.64
    teddy 40.46

  14. 4.234 is a decimal up to 2dp because if you pretend 234 was a number, you have to round it to the nearest 10 so, 234 rounded to the nearest 10 is 230. That makes the answer for 4.234 be 4.23.

    There are 0 ones, 2 tenths, and 3 hundredths. The number is 0.23.

    I have done the place value chart and my Mum will send all work I have done.
    There are 0 ones, 5 tenths, and 6 hundredths. There are 0 ones, 0 tenths, and 8 hundredths. There are 1 one, 4 tenths, and 8 hundredths. There are 2 ones, 0 tenths, and 7 hundredths.

    The 4 in 14.8 is in the ones. The 4 in 13.74 is in the hundredths. The 4 in 8.04 is in the hundredths. The 4 in 42.03 is in the 10’s. The 4 in 106.48 is in the tenths. The 4 in 176.4 is in the tenths.

    53 5.3 (0.53) 0.35
    0.53 has 3 in the hundredths. 12.73 has 3 in the hundredths. 0.13 has 3 in the hundredths.

    Alex could be thinking of 10 numbers.
    1.3
    1.31
    1.32
    1.33
    1.34
    1.35
    1.36
    1.37
    1.38
    1.39

    These are the numbers that I matched.

    5 ones, 6 tenths and 5 hundredths | 5.56
    5 tenths and 6 hundredths | 0.56
    5 ones, 5 tenths and 6 hundredths | 5.56
    6 tens and 5 hundredths | 60.05

    5.02 is not the largest number you can make because if you swap the tenths with the hundredths it changes the number to 5.2 which makes the answer false.
    It is true that the smallest number you can make is 0.25 because 2 is the smallest number other than 0 so it has to go before 5.
    Annie can make more than six numbers.

    Dexter is wrong because I found 61 other ways but I am only going to do 3.
    0.62 = 0.3 + 0.32
    0.62 = 0.15 + 0.47
    0.62 = 0.5 + 0.12
    Teddy’s number is 40.46. Amir’s number is 46.2. Rosie’s number is 46.02. And Eva’s number is 2.64.

    • Do you think this statement is correct: “5.02 is not the largest number you can make because if you swap the tenths with the hundredths it changes the number to 5.2 which makes the answer false.”
      If you have to use all 3 of the cards, and there is no need for a 0 after the 2 in 5.2, then is there an argument that 5.02 could be the largest number they can make with all 3 cards?

    • Ahmad, good to see you on the blogs. Can you look at this again and use the place value grid to help you. Please complete the rest of the challenges and blogs.

  16. 4.234 is a decimal up to 2dp because the decimals are appearing in the tenths and hundredths even though it has an extra column the decimal point still appears in the tenths and hundredths columns.
    I did the rest in my homework book and am going to send the work.

    • Hi Anis, its good to see you have done the work! Just be careful! 4.234 it not 2dp. Yes it has a tenths and hundredths column, but do not ignore the extra last column, which would be thousandths. This would make it 3dp. :)

  17. 4.234 isn’t a decimal up to 2 dp . The reason why is because that if it was a decimal up to 2 dp it would be part of tenths and the hundredths column but this is a 3 dp decimal because it is both is in the tenths , hundredths and thousandths column.

    • Ebraheem please check this again. One decimal place would mean just a ‘tenths’ column, so 2.64 would not work as this has a tenths and a hundredths column, therefore showing 2 decimal places. I would in put these numbers into your place value chart above and have another go :)

    • Adela, please watch the video and answer the questions in your homework book.
      Learning tip: Take your time to watch the video, so that you understand it well. Then, have a go at answering the questions, writing it out the way it is shown and presented well. I would like you to try your best and have a go please. Once you have completed the task, please email your work to us. Thank you.

    • Nehemia please check this again. One decimal place would mean just a ‘tenths’ column, so 2.64 would not work as this has a tenths and a hundredths column, therefore showing 2 decimal places. I would in put these numbers into your place value chart above and have another go :)

  18. Starter: it is isn’t a decimal up to 2 because there is not a decimal in the tenths and hundredths !

    Challenge!
    Dexter is wrong!
    Here are my thoughts!
    0.62
    0.00. 0.62

    0.62
    0.31. 0.31

    0.62
    0.04. 0.58

    Match them up!
    Teddy =
    40.46
    Amir=46.2
    Rosie=46.02
    Eva=2.64

    • Good effort Lexi
      For starter your reasoning is not correct . look at the number again (hint : how many digits are there after decimal).
      Well done for the rest :-)
