Questions about the Subtracting Integers poster

What’s on the Subtracting Integers poster?

The rule, 4 worked examples, and the mistake everyone makes. Subtracting is the same as adding the opposite. Change the sign of the second number,…; a − b = a + (−b); 5 − (−3) = 5 + 3 = 8; (−5) − 3 = (−5) + (−3) = −8; (−5) − (−3) = (−5) + 3 = −2; 3 − 8 = 3 + (−8) = −5; Common mistake: 5 − (−3) = 2 → 5 − (−3) = 8. Keep, change, change: keep the first, change the operation, change the second's sign.

Who is the Subtracting Integers poster for?

Subtracting Integers is filed under 6th Grade (ages 11–12), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.

When should you use the Subtracting Integers poster?

Rewrite it as an addition first, then use the addition rules. Two steps, no exceptions. A wall chart earns its place by being glanceable from where the work is happening, so Subtracting Integers belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.

What other posters go with Subtracting Integers?
