Aim: How can we multiply positive and negative fractions and decimals?
Homework: Multiplying Fractions and Decimals worksheet, both sides (found below)
1. Based on what we did on Tuesday, can you describe the algorithm for multiplying two integers?
2. What does 8 x (-6) mean?
3. What value will a negative divided by a negative divided by a negative have? Explain.
Classwork: As a reminder:
positive x positive = positive
positive x negative = negative
negative x positive = negative
negative x negative = positive
We expanded our rational numbers computational understanding to include multiplying positive and negative fractions. We then applied our understanding to multiply positive and negative decimals. As we discovered, the previous algorithms applied to all rational numbers.
