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
9. Count the objects in a set, 0 -20

Comparing and ordering

10. Compare equivalent and non-equivalent sets 1 –5 by matching without using symbols – more than, less than, the same as
11. Compare equivalent and non-equivalent sets 0- 10 by matching
12. Name the inequality: I have 2 more than you; 3 is less than 5
13. Order sets of objects by number, 1-5
14. Order sets of objects by number 0 -10
15. Use the language of ordinal number: first, last
16. Use the language of ordinal number: first, second, third, last

Analysis of number

Combining

17. 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
18. Explore the components o number, 1 -10
19. Combine sets of objects, totals to 5
20. Combine sets of objects, totals to 10

Partitioning

21. Partition sets of objects, 1-5
  1. partition sets of objects with a pencil or straw to show component parts
  2. record pictorially
22. Partition sets of objects, 0 –10
23. Use the symbols + and = to construct word sentences involving addition

Numeration

24. Develop an understanding of the conservation of numbers, 1 –5
25. Develop an understanding of the conservation of numbers 0 -10
26. Read, write and order numerals, 1 –5
27. Read, write and order numerals, 0 -10
28. Identify the empty set and the numeral 0
29. Tell at a glance the number of objects in a set, 1-5
30. Tell at a glance the number of objects in a set 2-10
31. Solve simple oral problems, 0 –5
32. Solve simple oral and pictorial problems, 0 -10

Extending patterns

33. Identify, copy and extend patterns in colour, shape and size
34. Identify, copy and extend patterns in colour, shape, size and number (3 – 4 elements)
35. Discover different arrays of the same number – how many different patterns of 10 can you make?
36. Recognise patterns and predict subsequent numbers – 2,3,4,___, 6, 7; 10, 9, __, __, 6.

Spatial awareness

37. Explore, discuss, develop and use the vocabulary of spatial awareness – over, under, up, down, on, beside, in
