# NA1-2: Know the forward and backward counting sequences of whole numbers to 100.

This means students will know the forward number word sequence to 100 is the counting pattern of words and symbols, 0, 1, 2, 3, 4... while the backward sequence is the pattern 100, 99, 98, 97... Students will also be able to name the number before and after a given number since this relates to taking an item off or putting an item onto an existing set.

- Students will be able to identify the sets within sets, especially the groups within 100 and within 10.
- Students will be able to use skip counting to count large sets.

- Putting numbers in order.
- Counting in different ways.
- Using number words.

- State when their birthday is and locate this on a calendar.
- Skip counting in 2s, 3s, 10s.
- Make groups of five using different combinations.
- Identify the diverse ways people celebrate birthdays in New Zealand.

- Understand that the number of objects in a set stays the same as changes are made to:
- spatial layout
- size
- colour

- Understand that the count of a collection of objects can be trusted and worked from as:
- objects are added or taken away
- the set is rearranged into parts 300

use a number line to order numbers to 100

Students will be able to identify pairs of features for counting by 2s.

Students will be able to create equal sized groups and count the total set either by counting all or by skip counting.

Students will be able to create models of equal sized groups using materials to represent features in a book300

explore attributes of numbers between 1 and 100

- Understand that the number of objects in a set stays the same as changes are made to spatial layout, size, or colour.
- Understand that the count of a collection of objects can be trusted and worked from as objects are added or taken away, or the set is rearranged into parts.

- Use counting to find the number when two different collections are compared (difference).
- Use counting to find the number when two or more collections are joined (addition).
- Use counting to find the number when objects are removed from a collection (subtraction).
