Integers
Integers give students the full number line — positive and negative, with zero at the centre. Adding a negative number is the same as subtracting its opposite. Students who understand why −3 + (−5) = −8 have genuinely extended their number sense, not just memorized a rule.

Key ideas
Represent integers on a number line. Compare and order positive and negative integers. Add and subtract integers using concrete materials and number lines. Apply integer operations to real-world situations: temperature, elevation, finance.
Putting it together
Apply these ideas through hands-on activities, guided practice, and real-world problems.
