Task: WALT: Use appropriate scales, devices, and metric units for length, area, volume and capacity, weight

Measuring is about making a comparison between what is being measured and a suitable measurement unit. Central to the development of measuring skills is lots of practical measuring experience. Also important is the reality that measurement is never exact.
Required Resource Materials:
  • Oranges
  • Measuring equipment including; rulers, scales, measuring jugs.
Activity: Complete the questions below:
  1. How can you measure an orange? (there will be multiple answers for this, list as many as you can think of). Weight,Length,Width,Capacity.Think of the attributes of an orange eg juice. Juice and inside
  2. Choose two of these attributes of an orange to measure and carry out the task. Write up a proposal for your investigation, including details on:
    • Attribute being measured
    Juice and inside
    • Equipment required
    Knife, chopping board, cup and spoon
Method (step by step)
Cut orange
Squeeze the juice out of the orange  220 weight of insides  50 mls juice
Measure the juice
Peel out the inside of the orange
Measure the inside of the orange     
      How will you present your results?
    Google doc
    • Write up your results
  1. What were successful/unsuccessful approaches to measuring each of your chosen Attributes? Why? I think that squeezing all of the juice out of the orange was a bit of both as it made a mess but we got most of the juice in a container.
  2. With the inside of the orange I think it didn’t go very well because first using a spoon didn’t work but then we tried a knife and it kinda worked.   220 weight of insides  50 mls juice
  3. Choose 4 other objects to measure in the class - use 4 different measurements eg measure the length of something and the weight of something else. Write up your results in a table.  Pencil-length=17cm  book-width=20.5cm  scissors-weight compare with 4 highlighter= highlighter are just heavier  drink bottle- capacity= 760mls

My next step is to have a teacher conference and find a new goal

In Maths we have been learning to use a range of multiplicative strategies when operating with whole numbers.

The strategies we have been learning are:

- Estimate the reasonableness of large problems like 1 788 – 891. Could 497 be right?
- Use multiplication to solve addition and subtraction problems eg.
  64 – 48 = as (8 x 8) – (6 x 8) = 2 x 8= 16
- Use doubling / halving, trebling/ thirding and adjusting to solve multiplication problems,
 eg.  12 x 50 solved as 4 x 150= 600
- Use an algorithm to solve multiplication problems.
- Solve problems using simple cube numbers .
- Use an algorithm to solve division problems.

Here is a link to my Multiplicative Strategies Assessment which shows that I know why and how I use particular strategies. This doc also has screenshots to show which IXL activities I have completed as part of my learning.

My next step in my Maths Learning is…… long division
