| Counting Stick or Spider Diagram as in Sparks 3, Sparks 4 or Sparks 5 Fractions, Decimals, %ages
review concept that F, D and % are all parts of a total (unlike ratio), and so are all linked.
|
Use equivalence of F, D and % in describing proportions
(Proportion compares part with whole and is usually expressed as a F, D or %).
Proportion and notation 3:2,
in addition to:
Numerator, denominator,
mixed number,
improper fraction,
unit fraction,
cancel, simplify,
equivalent, convert,
decimal fraction,
recurring decimal,
percentage.
|
Introduce language of proportion, eg: with OHS N4/1: School Dinners
(focusing on F, D, % and P).
Eg: 6 in 8 like school stew ...
6 out of 8 like school stew ..
6/8 ...0.75 ...75%
|
Learning activities which require a focus on comparing part with total.
Develop introductory task so that pupils can apply language of proportion interchangeably with that of F, D and %.
Eg:
Pupils could complete a series of statements from OHS N4/1: School Dinners, such as:
2 in 8 dislike stew ... 1/4 dislike it ... 3/4 like it ... 75% like it ...
