# Level Two: Number and Algebra

#### New Zealand Curriculum Level 2

In a range of meaningful contexts, students will be engaged in thinking mathematically and statistically. They will solve problems and model situations that require them to:

#### National Standards

In contexts that require them to solve problems or model situations, students will be able to:

#### Year 4

Number strategies
• use simple additive strategies with whole numbers and fractions
Number knowledge
• know forward and backward counting sequences with whole numbers to at least 1000
• know the basic addition and subtraction facts
• know how many ones, tens, and hundreds are in whole numbers to at least 1000
• know simple fractions in everyday use
Equations and expressions
• communicate and interpret simple additive strategies, using words, diagrams (pictures), and symbols
Patterns and relationships
• generalise that whole numbers can be partitioned in many ways
• find rules for the next member in a sequential pattern.
• apply basic addition facts and knowledge of place value and symmetry to:
- combine or partition whole numbers
- find fractions of sets, shapes, and quantities
• create and continue sequential patterns with one or two variables by identifying the unit of repeat
• continue spatial patterns and number patterns based on simple addition or subtraction.
• apply basic addition and subtraction facts, simple multiplication facts, and knowledge of place value and symmetry to:
- combine or partition whole numbers
- find fractions of sets, shapes, and quantities
• create, continue, and give the rule for sequential patterns with two variables
• create and continue spatial patterns and number patterns based on repeated addition or subtraction.
