Place Value in Year 4

Year 4 have been continuing to develop their place value understanding this term by using concrete resources such as place value counters and dienes to support them. 

This week we have been exploring what happens when you subtract or add 1, 10, 100 and 1000 from any given number. The children have made sure to follow their steps to success by identifying the column that they need to focus on and then adding or subtracting from that column. 

In Larch class, the children challenged each other with a fun place value game. Partner A covered their eyes as partner B removed one counter from a column. It was then up to partner A to spot which column had changed and what the new number was! 

" When I was subtracting 1000, I got confused to start with because I wasn't looking at the right column. Now I know that the hundreds, tens and ones stay the same, it's only the 1000s that change." Ella, Larch

"I know that I need to only add or take away one thousand place value counter or diene in the thousands column. The other digits in the place value columns stay the same." Keira, Ash

In Birch class, the children were asked to make the number 490 and then add another 10. Daisy and Ruby realised that both the hundreds and tens column changed as the answer was 500! We will definitely explore this some more as the year goes on.

Excellent work year 4, as always!
