564, 600 to the nearest 10 000 is 560,000.

889, 455 to the nearest 100 000 is 900 000.

What is the nearest 1000 number to 64, 200?

What is the nearest 10 000 number to 363, 500?

Round 758, 100 to the nearest 100 000.

 

Identify common factors.

Identify common multiples

Common multiple: Multiples that are common to two or more numbers are said to be common multiples.

E.g. Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, …

Multiples of 3 are 3, 6, 9, 12, 15, 18, …

So, common multiples of 2 and 3 are 6, 12, 18, …

What are the common multiples of 4 and 8?

 

What are the common multiples of 6 and 12?

 

 

 

Identify prime numbers

A Prime Number can be divided evenly only by 1 or itself.

e.g. 7, 11, 13, 17, 19.

Explain why 22 is not a prime number.

What is the next prime number after 19?

 

Multiply and divide numbers by 10, 100 and 1000 giving answers up to three decimal places

 

903 ÷ 10 = 90.3

903 ÷ 100 = 9.03

903 ÷ 1000 = 0.903

 

Find the missing number:

903 x ? = 9030

903 x ? = 90300

903 ÷ ? = 0.903

 

Recall and use equivalences between simple fractions, decimals and percentages, including in different contexts.

 

1 = 1.0 = 100%

½ = 0.5 = 50%

¼ = 0.25 = 25%

¾ = 0.75 = 75%

= 0.1 = 10%

 

= 0.2 = 20%

 

What is the equivalent to ¾?

I got 50 out of 100in a test and my teacher said I scored 50%. Is she correct?
