Scale factors: Ratios and Proportions
Learners create building and models using scale factors. In this geometry activity, students apply the properties of ratio and proportion to solve problems. They identify the means and extremes property of cross multiplication.
Curated OER
Ratio Relationships
Students solve for the different ratio and proportion of a problem. In this geometry lesson, students show their knowledge of how to solve proportional relationships. They convert between percent, decimals and fractions.
