WALT: read scales to find increments.


Yesterday, you learned about volume and capacity as well learning how to read scales accurately and effectively.


Today will be about applying what you learned to confirm your understanding.  We will also look at how you can adapt the ingredients required in recipes for a different amount of people.


First of all, it is important to remember the number of millilitres in a litre and grams in a kilogram.  As you were shown in the video yesterday, it will also be beneficial to know the number in parts of a litre and parts of a kilogram.  Can you remember?


There are:

1000 millilitres (mls) in 1 litre (l)                                 1000 grams (gs) in 1 kilogram (kg)

500 millilitres in 1/2 a litre                                           500 grams in 1/2 a kilogram

250 millilitres in 1/4 of a litre                                       250 grams in 1/4 of a kilogram.


Your first task is to have a look at the file in Resources called 'Increments on a Scale'.  Choose your challenge (1, 2 or 3) and see if you can work out what each own the increments are.  Try to remember how you work this out.  Look at the numbers on the line and divide the number or smaller lines to give you your answer.


Once you have completed this activity, look through the powerpoint in Resources and then choose the relevant challenge in the Activity Sheet to complete.  The challenges are differentiated by the number of stars at the bottom of the page.
