Grade 9
Number
demonstrate an understanding of powers with integral bases (excluding base 0) and whole number exponents
determine the square root of positive rational numbers that are perfect squares
determine an approximate square root of positive rational numbers that are non-perfect squares
Patterns and Relations
generalize a pattern arising from a problem-solving context using linear equations and verify by substitution
demonstrate an understanding of polynomials (limited to polynomials of degree less than or equal to 2)
Shape and Space
solve problems and justify the solution strategy using circle properties
Statistics and Probability
describe the effect of bias, use of language, ethics, cost, time and timing, privacy, and cultural sensitivity on the collection of data
demonstrate an understanding of powers with integral bases (excluding base 0) and whole number exponents
