Thursday 26th March 2020 – Year 5: (Representing Fractions)

Day 8 Crew! Happy Thursday! Today we are recapping how we can represent fractions using a bar model.

Remember a bar model is a pictorial diagrams showing both the numerator and denominator as equal parts. The Denominator is the number of equal parts in total (Do not forget the denominator does not change). The numerator is the number of equal parts shaded in.

Examples of Bar Models

Do not forget to SIMPLIFY if possible for some answers. For example, 25/45 you do not need to do a bar model of 45 boxes! you can simplify 25/45 to 5/9 because 5 goes into both 25 and 45, so a bar model of 5/9 is perfect!

Answer all the questions below, draw the bar models and identify each fraction.

    • Hi Marvin, hope you’re well. If you have another note book at home to use feel free to use that. Otherwise there are 2 options I can think of:
      1) do your written work on paper and keep it in a box/folder/one safe space.
      2) do your written work on a word document and keep track of it. You can either save a new one each day, or keep one document and put in a date and title. Then you only have to do handwriting on paper (and your handwriting is excellent!)

    • Good work Sarina, but these need to be done as bar models in your book too, if you can. You will need to use a ruler and measure the blocks. Remember the vars always need to be the same size.

  4. Hello I did the silver challenge. Mr Inman video really helped me understand. My mum helped me with the first one and then I did it by myself. 30/70= 3/7 they are both a multiple of 10 so I divided by 10. I find dividing a bit tricky so I counted on.

    • Great work Keisha .Please explain how did you represent question no 14 from silver . How many bars did you have to draw? How many parts you shaded?
