Mathematical Definitions 2

Today we looked at abundant numbers, we came up with some new definitions:

Abundant numbers: Where the factors of the number except itself, add up to higher than the number itself. For example: 24, because 1+2+3+4+6+8+12 = 36, which is greater than 24. However, 9 is not an abundant number because 1+3 = 4 (less than 9). Evie Gribben. 

Common factor: Is if you have two or more numbers that have the same factors. For example, 6 and 12 have the common factors: 1, 2, 3 and 6. Kevin Guan.

Highest common factor: The factors of 6 are 1, 2, 3 and 6. The factors of 12 are 1, 2, 3, 4, 6 and 12. Therefore, the highest common factor here is… 6. Kasey Wright.

 

Key Skills Half Term

Literacy:

Everyone was given their writing targets today. With these targets you must write a short story which includes a focus on that. For example if one of the targets was to structure all writing into appropriate paragraphs, the story would then contain appropriate and clearly structured paragraphs.

 

Numeracy:

(Apologies for the lengthy explanation)

So far in Maths this term we have looked at the following topics:

  • Place value (tenths, hundredths, etc.).
  • Grid method (multiplication in general).
  • Sequences.
  • Rounding whole numbers.
  • Multiplying by  10/100/1000 and dividing by the same numbers.
  • Adding and subtracting decimal numbers.
  • Different types of numbers; prime, square, factors and multiples.
  • 2d shapes.
  • 3d shapes.
  • Short division/bus stop method.

That is a short run-down, within those we have explored them a lot deeper. Hopefully those titles will allow you to remember. You have 3 tasks to complete:

1. Set 10 (or more) questions for a person at home to complete, then mark these. If they are wrong – can you explain why?

2. Set yourself some questions for 3 topics from above (any of them). Complete and check them so they are all correct.

3. Practise a times table which you are not perfect on. Move on to the next number and practise these.

 

These tasks are open-ended, therefore you can challenge yourself as much as you feel necessary.

Key Skills 18/10/13

Numeracy: 

Using the short division (bus stop) method, can you complete twenty questions of your own choice. These should be at least dividing hundreds, by any number apart from 1,2 or a multiple of 10.

Literacy:

Research Michael Morpurgo. Your research could, for example, answer the following questions:

Who was he? What does he do? What style of writing does he do? Have you read any of his books before?

 

 

Key Skills 11/10/13

Literacy/Creative curriculum Key Skills:

Research something (anything) about World War 2 that you don’t know already.

Present it however you like, in the form of a poem, powerpoint, key skills book, meccano… It’s entirely up to you.

 

Numeracy: 

This was 4 sheets of questions (only 12) looking at the different things we have been doing this term. 

Mathematical Definitions

This week we have learnt about number facts and shape facts!

Here are some definitions:

Prime number = Only divisible by itself and 1 (to make a whole number). The only even one is 2, and 1 is not a prime number as it only has one factor (1). (Evie Gribben)

Squared number = A number which has two factors which are the same. For example, 16 (4 x 4) (Tyla Pritchard).

Circle = Infinite amount of lines of symmetry, only has one side. (Jasleen Kauruppal).

Squared Root = The number that you times by to reach the squared number. (Rohan Sehmi).

Right Angle = 90 degrees, looks like an L, there’s four in a square and a rectangle (Julia Januszewska).

Here are a few definitions, please comment with more 🙂
