This week, we started our first unit of place value which involved us adventuring into numbers in the thousands for the first time. We have been brilliant at counting in thousands and representing these numbers in multiple ways including using counters, dienes, using a part-part- whole and partitioning.
10 hundreds = 1 thousand
100 tens = 1 thousand
1000 ones = 1 thousand
This week, we have been focusing on placing and identifying numbers to 10,000 on a numberline and also finding 10, 100 and 1000 more or less than a given number.
This week, we have learned a new skill of rounding to the nearest multiple of 10, 100 and 1000 using a numberline to help us. We have had to draw on lots of skills including counting in 10s, 100s and 1000s for any given number.
Our key stem sentences below have been very helpful!
Rounding to the nearest 10:
If the digit in the ones column is 4 or less, you round down.
If the digit in the ones column is 5 or more, you round up.
Rounding to the nearest 100:
If the digit in the tens column is 4 or less, you round down.
If the digit in the tens column is 5 or more, you round up.
Rounding to the nearest 1000:
If the digit in the hundreds column is 4 or less, you round down.
If the digit in the hundreds column is 5 or more, you round up.
We have now moved onto our first block of addition and subtraction in which we have been focusing on recapping both our mental and written methods from Year 3 before moving onto applying these skills to solve word problems. We have been working on our reading skills to support us in interpreting both 1 and 2 step written problems.
