Week Commencing: 25th September 2017

 

This week we have used our knowledge of place value to put numbers on a numberline.  For example, if the start of the numberline is 600 and the end of the numberline is 700, where might 660 be?  We have talked about how it is easier to find the middle number, in this case 650 and then work backwards or forwards from there.  Sounds easy but it is quite challenging for the children.  This is what the homework is based on.

 

We have also started the process of teaching the children how to add and subtract using the formal written method.  Below are two posters explaining how we teach it.  Please note that we have only done this using the dienes equipment so we are not expecting them to be able to record it like this yet!

Week Ending: 23rd September 2017

 

This week we have been adding ones, tens and hundreds to a 3 digit number.  They have found this quite difficult.  We have used the dienes equipment to try and demonstrate what happens to each number, especially when crossing the boundaries.  For example, when working out 357 + 4, we not only have to change the units but also the tens to.  We will be continuing work on this during our mental starters as it is a very important skill.

 

As well as this we have been counting in 50s and recognising how it is similar to counting in 5s.  For example, 0, 50, 100, 150, 200 is similar to 0, 5, 10, 15, 20.  We have also looked at numbers and compared them, putting them in order from smallest to largest using our knowledge of place value.

Week Ending: 15th September 2017

 

In Maths, we have been looking a lot at place value, for example, in 458 we have focussed on what each number represents, in this case 400, 50 and 8. We have used this knowledge to add and take away 10 and 100 from a number, write numbers in words and numerals and we have partitioned numbers.  They are getting there but can find it difficult to reason using these skills.  We have also practised counting in 4s and 8s.

 

See below for a number generator where you can put in the starting number and the steps you want to jump and it generates numbers.  You can hide or show the numbers so it is nice to get the children to work out which one comes next!  In year 3, one of the targets is to count forwards and backwards in 4s, 8s, 50s and 100s.

 

The homework this week should be self explanatory!
