This week in Maths we been looking at our doubling facts. Using our knowledge of doubles from 1-10 and our ability to partition or break down larger numbers into tens and units we practised doubling each part of the number before combining them to work out the final answer. In the pictures below we used tens and units equipment to visualise what we were doing.
e.g. double 34:
34 is partitioned into 30 and 4.
Double 30 is 60
Double 4 is 8
Altogether the total is 68
Double 34 is 68.
Have a look at this website for some more doubling by partitioning practise:
