Strand Unit: Classifying

The child should be enabled to:

1.

Classify objects on the basis of one attribute such as colour, shape, texture or size

  1. sort collections of objects
  2. add similar objects to a clearly defined set
2.

Identify the complement of a set (elements not in a set)

  1. categorise objects such as things I like /don’t like
  2. red things / things that are not red

Matching

3. Match equivalent and non-equivalent sets using one to one correspondence
  1. match pairs of identical objects
  2. match pairs of related objects
  3. match equivalent and non-equivalent sets to establish the concepts of more than, less than, enough, as many as

Comparing

4. Compare objects according to length, width, height, quantity, thickness or size
  1. introduce concepts long, short, longer, shorter
5. Compare sets without counting

Ordering

6. Order objects according to length or height
7. Order sets without counting

Counting

8. Count the numbers of objects in a set, 1 – 10

Comparing and ordering

9. Compare equivalent and non-equivalent sets 1 –5 by matching without using symbols – more than, less than, the same as
10. Order sets of objects by number, 1-5
11. Use the language of ordinal number: first, last

Analysis of number

Combining

12. Explore the components of number, 1-5
  1. identify the ways in which the numbers can be modelled using concrete objects: 4 and 1
  2. identify pairs of related facts: 1 and 2 is the same as 2 and 1
13. Combine sets of objects, totals to 5

Partitioning

14. Partition sets of objects, 1-5
  1. partition sets of objects with a pencil or straw to show component parts
  2. record pictorially

Numeration

15. Develop an understanding of the conservation of numbers, 1 –5
16. Read, write and order numerals, 1 –5
17. Identify the empty set and the numeral 0
18. Tell at a glance the number of objects in a set, 1-5
19. Solve simple oral problems, 0 –5

Extending patterns

20. Identify, copy and extend patterns in colour, shape and size

Spatial awareness

21. Explore, discuss, develop and use the vocabulary of spatial awareness – over, under, up, down, on, beside, in
22. Moving in straight / curved lines, in a circle, finding own space

3-D shapes

23. Sort 3-D shapes, regular and irregular
24. Solve tasks and problems involving shape

2-D shapes

25. Sort and name 2-D shapes: circle, square, triangle, rectangle
26. Directed sorting of 2-D shapes on the basis of different criteria – round /not round; thick / thin
27. Use suitable structured materials to create pictures
28. Solve problems involving shape

Length

29.

Develop an understanding of the concept of length

30.

Discuss objects in the environment: long/short / tall / wide / narrow / longer / shorter / wider than

31.

Compare and order objects according to length or height

Weight

32.

Develop an understanding of the concept of weight through exploration and use of appropriate vocabulary: heavy /light ; heavier /lighter ; balance /weigh

33.

Compare objects according to weight

Capacity

34.

Develop an understanding of the concept of capacity through exploration and the use of appropriate language: full / nearly full; empty/ holds more /holds less/ holds as much as

35.

Compare containers according to capacity

Time

36.

Develop an understanding of the concept of time through exploration and the use of appropriate language: morning/evening/night / day / lunchtime /bedtime / early /late/ days of the week /school days /weekends

37.

Sequence daily events or stages in a story

Money

38.

Recognise and use coins up to 5c

39.

Solve practical tasks and problems using money

Data

40.

Sort and classify sets of objects by one criterion – shape, colour, size, texture and function

41.

Match sets, equal and unequal – enough / more / as many as / less

42.

Represent and interpret a set of simple mathematical data using real objects, models and pictures
