Do your students lose track of the signs? This 38-slide interactive lesson takes KS3 students from representing directed numbers on a number line to calculating with them confidently.
Students learn that a directed number is written with a positive or negative sign, and that 5 is really +5. They use a number line to add and subtract, for example −2 + 5 = 3 and 5 − 8 = −3, then move to the rules for like and unlike signs so they can calculate without the line. The lesson goes on to multiplication and division, evaluating algebraic expressions and solving two-step equations.
A dependable addition to a KS3 number and algebra topic, giving students a clear route from the number line to written rules. Confidence with directed numbers is one of the biggest predictors of success in later algebra.
