Subtraction

Number and number processes

I can use addition, subtraction, multiplication and division when solving problems, making best use of the mental strategies and written skills I have developed.
MNU 1-03a

Expressions and equations
I can compare, describe and show number relationships, using appropriate vocabulary and the symbols for equals,

not equal to, less than and greater than.

MTH 1-15a

When a picture or symbol is used to replace a number in a number statement, I can find its value using my knowledge of number facts and explain my thinking to others.
