 uses patterns to extend number facts
eg 5  2 = 3, so 500  200 is 300
 explains and records methods for adding and subtracting
 uses a split strategy for addition or subtraction
 uses an empty number line and jump strategies to represent
solutions to addition and subtraction problems involving
three- or four-digit numbers
using concrete materials
 uses the formal written algorithm to solve addition or
subtraction problems
 uses a calculator to solve addition and subtraction problems
that include larger numbers contained in a problem context
Foundation Statements
Count, order, read and record numbers up to 9999 and use mental
and written strategies, including the formal written algorithm, to
solve addition and subtraction problems involving numbers of up
to 4 digits.
Ask questions and undertake investigations, selecting appropriate
technological applications and problem-solving strategies.
Use mathematical terminology, and some conventions and give valid
reasons when comparing and selecting from possible solutions, making
connections with existing knowledge and understanding.
