OUTCOME
A student:
MA2-8NA: generalises properties of odd and even numbers, generates number patterns, and completes simple number sentences by calculating missing values
TEACHING POINTS | In Stage 2, number patterns include additive patterns that increase or decrease from any starting point. |
LANGUAGE | Students should be able to communicate using the following language: pattern, goes up by, goes down by, even, odd, rows, digit, multiplication facts. |
Expectations of Attainment
Describe, continue and create number patterns resulting from performing addition or subtraction (ACMNA060) | identify and describe patterns when counting forwards or backwards by threes, fours, sixes, sevens, eights and nines from any starting point |
model, describe and then record number patterns using diagrams, words or symbols | |
– ask questions about how number patterns have been created and how they can be continued (Communicating) | |
create and continue a variety of number patterns that increase or decrease, and describe them in more than one way |
Investigate the conditions required for a number to be even or odd and identify even and odd numbers (ACMNA051) | model even and odd numbers of up to two digits using arrays with two rows |
– compare and describe the difference between models of even numbers and models of odd numbers (Communicating) | |
– recognise the connection between even numbers and the multiplication facts for two (Reasoning) | |
describe and generalise the conditions for a number to be even or odd | |
– recognise the significance of the final digit of a whole number in determining whether a given number is even or odd (Reasoning) | |
identify even or odd numbers of up to four digits |
