Place Value
This week we have been learning all about how to partition a 2 digit number into tens and units using dienes apparatus. We split the numbers and added the tens then added the units, showing our working out like this:
46 = 4 tens and 6 units which is 40 + 6.
We also had a go at using arrow cards so we could see how Mr 0 gets squashed every time a bigger units number comes along! We have played lots of fun games such as place value bingo and 'guess my number' where each child has a different number card and says for example, 'I have 4 tens and 3 units...what am I?'
Here are some great interactive websites we have been using in class to help us with our understanding:

We have also been ordering numbers on a number line from 0 - 100. We learnt the importance of looking at the tens number to help us order the numbers from smallest to largest. If there are two numbers which have the same tens number, then we must look at the units number! We used the symbols < and > to show which number is bigger and which number is smaller. Here is another great game you can play at home:
