WC:12/11/18

Our maths objective this week is to round numbers to 1,000.

We will be reasoning and problem solving, rounding 4 digit numbers to the nearest 10, 100 or 1,000.  

Examples at expected level include:

 

Which multiples of 1,00 doe these numbers sit between?

 

      ...3,000....     3,200      ...4,000......

 

Which numbers round to 4,500 to the nearest 100?

 

                      4,534                4,590

 

                      4,495                4,525

 

 

Word problems such as: "My number rounds to 1,000 and has 2 ones" What's my number?

                          1,332    or     1,502         

 

Sinead is rounding numbers to the nearest 1,000. She says, "I think that 7,523 rounded to the nearest 1,000 is 7,000. Is Sinead correct? Explain, giving reasons for your answer.

Sinead is incorrect.Her number rounds to 8,000 because the digit in  the hundreds column is 5 so it rounds up to the next thousand.

Our maths objectives this week are related to Number/Place Value

  • To order numbers beyond 1000
  • To compare numbers beyond 1000
  • To find 1000 more, 1000 less than 1000.

 

We will be using the mathematical symbols < less than and > greater than to compare numbers.

Children will also be still using the thousands frame to concrete model examples.

Children will also be looking at reasoning and problem solving with these objectives.

An example at expected level is as follows;

 comparing       1515>1155

ordering  from the smallest to the greatest      272, 722, 727, 2277, 2727

Reasoning and problem solving                  10 less than my number is 1,000 more than 5,300, What is my number?    (6,310)     Children may then take this further by creating their own word problems for others to solve.

Our maths objectives this week are related to Number/Place Value

  • To order and compare numbers beyond 1000

 

You can use the Th,H,T and U frame to help your children understand this.

We will also be comparing numbers, using the signs < less than and >greater than

Knowledge of where numbers are on a 1,000 and a 10,000 number line will help children begin to understand where numbers are placed when using blank number lines and numbers that are posted at the beginning and end.

I have shown some models for the children to begin to understand this concept.

 

 

WC: 15/10/18

Our maths objectives this week are related to Number/Place Value

  • To count in 1000's
  • To understand place value in 4 digit numbers; 1000's, 100's, 10's and 1's
  • To partition numbers

To help your children understand and break down numbers to partition, a frame is a really good visual cue...

 

I have sent home a paper copy of a TH,H,T,O frame for you to use. You can place it in a plastic wallet and use a dry marker on the front to write numbers or alternatively use counters/lego bricks to help children understand what each number/amount is representing.

Children have then partitioned up to 5/6 digit numbers in their expanded form. For example, 

4,689   can be partitioned as: 4,000+600+80+9.

WC: 1/10/18

Our maths objectives this week are related to Number/Place Value

  • To round numbers to the nearest 100
  • To round numbers to the nearest 1000

WC: 23/9/18

Our maths objectives this week are related to Number/Place Value

  • To know and learn Roman Numerals to 100
  • To explore what is the same and what is different between the number systems, for example there is no zero.
  • To round numbers to the nearest 10.

WC: 17/9/18

Our maths objective this week is related to Number/Place Value.

  • To find 1000 more or less than a given number.

WC: 10/9/18

Our maths objective this week is related to Number/Place Value.

  • To count in multiples of 6, 7, 9, 25 and 1000.
  • To find 1000 more or less than a given number.
