Unit 3b- exploring ratios and proportional relationships
In this unit students are expected to
7.PAR.4.6 Solve everyday problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at different scale.
7.PAR.4.8 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. 7.PAR.4.9 Use proportional relationships to solve multi-step ratio and percent problems presented in applicable situations.
7.PAR.4.11 Analyze sampling methods and conclude that random sampling produces and supports valid inferences. 7.PAR.4.12 Use data from repeated random samples to evaluate how much a sample mean is expected to vary from a population mean. Simulate multiple samples of the same size.
