Teacher's field guide

What Students Need to Do: Students calculate with positive and negative whole numbers in mixed problems. They choose the correct sign and find an accurate value for each result.
What Mastery Looks Like: Students solve mixed integer calculations quickly and accurately. They apply sign rules correctly and can check multiplication with division or addition with subtraction.
Common Misconceptions: Students may treat every pair of negative signs as positive, even in addition or subtraction. They may also confuse subtracting a negative with adding a negative or ignore the sign when dividing.
How to Assess It: Give this exit ticket: solve −8 + 13, 6 − 15, (−4)(−7), and −36 ÷ 9, then explain one answer's sign.

Lesson moves

Use two-color counters to model −4 + 7 and 3 − 8, then write an equation for each model.
Ask students to explain why (−6)(−3) is positive while −18 ÷ 3 is negative, using a pattern or number line.
Play integer operation bingo by calling expressions while students cover matching answers and justify disputed signs.
Give students a bank ledger with deposits, withdrawals, repeated fees, and equal repayments, then have them calculate each balance change.
