Number Line: What's wrong?

31 comments:

  1. In the first picture, the intervals are not equally segmented and there is no space to complete the number line.
    In the second picture, the number line is not completed.

  4. In the second picture, the number line is not completed by a ellipsis.

  5. 1 it is not a straight line and the spacing is different
    2 No because we cannot see many numbers. We should list all numbers.

  6. 1. It is not straight
    2. It is not equally divided
    3. on the second line there is an arrow which says the time line finished there but there is another timeline


    Question 2
    Yes we can

  8. They are not equally divided and the lines are not straight

  9. 1. The first number line is wrong as the drawer used and arrow to continue the number line in another location. We could improve by drawing a longer number line and plan our space. The space between the numbers are also not equal.
    2. No. We cannot represent the number lines like that as people would not understand the numbers in between.

  10. The errors are..
    The line is not straight, the differences between each interval are unequal, he should use multiples of two instead of one as there are many numbers and he has to draw a second line and the numbers are nearly mushed together.

    We should not represent it in this manner, instead he should use a larger number to represent each interval.

  11. 1. Line is not straight. Lines could be drawn straight. Spaces are not equal.
    2. The number line is incomplete.

  12. The number line is not straight. The gap between every number is also different. One of the number lines also does not have consecutive numbers.

    No. The number line is not complete and the dots makes it not a straight line. All the person needs to do is make the numbers at different intervals

  13. The number line is not straight and the intervals are not equal. It can be improved by using a ruler to straighten the line and mark out the equal intervals.

    We can represent a number line that way but if calculations are going to take place within the "..." then the calculations and the intervals it is on should be seen

  14. 1a. The number line is not straight and the intervals in between each number is not the same.
    1b. We could use a ruler to make the line straight and to measure the length of the intervals in between each number.
    2a. No, we cannot represent it in this manner.
    2b. We should draw it with bigger intervals of numbers instead of all the numbers.

  15. It is not a straight line and the intervals are not evenly paced out. Instead of making such a long number line he could put higher digits on it eg._2_4_6_8... instead of the usual _1_2_3_...
    No she can't she can write it in intervals like the above eg.

  16. 1)there is no degree sign and the line is messy and they are not equally segment, and too many arrows.

    2)he/she must have chose a multiple of 301

  17. 1. The number lines are not straight, the lines are not divided equally and the line is continued at the bottom.

    2. No, the number line should not be represented like this. Then the numbers should be divided into bigger parts so all the numbers can fit.

  19. We can use bigger number for the second interval

  20. 1.The number line spacing is not right thus, it was not consecutively done.
    2.This is wrong the number line should use larger numbers so the number line will not be suddenly separated.

  21. Qn1 : They lines are nt straight and the numbers are not equally divided.

    Qn2: The number line cannot be represented in this manner.We should make the numbers skip (e.g. 1, 5, 10).

  22. 1. The number line is not straight and the number of negative numbers is lesser than the number of positive numbers which makes the number line not equal.For the temperature number line, the positive numbers and the negative numbers are different not in the form of the negative signs.

    2. I don't think this is allowed cause as there are from small numbers to suddenly the last number of the number line.I think they should reduce the numbers at the end of the number line to smaller numbers so as not to leave out any numbers.

  23. Q1. The first number line is not equally divided and the line is not straight.
    Q2.No, it cannot be represented like that. We can use larger intervals like 100 per interval.

  24. First Picture:
    The number line is broken up into 2 parts when it should be just one straight line and it is all over the place. He could make consecutive numbers.

    Second Picture:
    No, he cannot leave it in this manner. We should consider about whether to use consecutive numbers in the multiple of a certain number for the 'big-ranged' number line. He could have used the method mentioned to make his number line.

  25. 1. The number line is NOT straight line. We should draw a straight number line with a ruler. The space between the numbers are not the same. We should use measurements on the ruler.
    2. NO. IF the number line is to long, we should instead have bigger numbers replacing these numbers so the number line would be complete. Example, if the number at the end is 100, we could put 0, 10 ,20, 30, 40, 50, 60,70,80,90,100.

  26. Q1: The number line is NOT a a straight line. The numbers are not equally divided. The number line is too long and the one end of the number line was cut halfway, and continued on the next line.
    Numbers and lines should be written more clearly.
    Q2: We could break up the numbers in larger intervals. And we can represent the number line in the manner shown in the second picture.
    Q3: We can represent a 'long' number line in THAT manner.
    Q4: We still have to consider the the equally divided part. The DOTS should be the same number at each sides.

    I'm naggy. :P

  27. And also in the first picture, the numbers are not equally divided

  28. 1)The number line is not straight.There is also no equal intervals in between each number. the line should be straightened and the intervals should be equal.

    2)We should not represent the number line in that way.If the number is to long then we should then skip equal amount of numbers.

  29. A1) it is not straight and the numbers are not equally divided. The number line was broken up and "joined" by arrows.

    A2) No. If the number is too big, then we should make the intervals bigger.

  30. Q1:
    1st:The number line is not straight.
    2nd:The intervals between the numbers are not equally segmented.
    3rd:The unit "Degrees Celsius" is not present.

    Q2: No, you cannot represent a long number line in that manner, this will result in unequal segmented intervals. We should first consider how long the number line would be, so you can make your number intervals bigger.
