LO-Partition numbers in different ways

 

Yesterday we looked at how to partition numbers into their tens and ones. Today we are going to write calculations for partitioning the numbers in different ways. Look at the power point below to see how we can partition differently. 

We partition numbers in different ways by moving the tens each time. 

For example, 

43                                                             76

40 + 3 = 43                                               70 + 6 = 76

30 + 13 = 43                                             60 + 16 = 76

20 + 23 = 43                                             50 + 26 = 76

10 + 33 = 43                                             40 + 36 = 76

 

Look at the numbers below. Can you write 4 different ways to partition each number? Set out your learning in your book like the examples above. Remember to just move a ten each time. 

 

1.   51

2.   79

3.   47

4.   83

5.   65
