## Welcome to Quantitative Literacy 1

The Quantitative Literacy I course is a course designed to introduce students to basic and some intermediate concepts of number sense and quantitative analysis. The course is also designed to help students conceptualize abstract quantitative concepts as they relate to real-world problems and everyday life. The course provides extensive examples and practice to help students explain and apply the concepts. It also covers basic number sense, algebraic concepts, Geometry and visual modeling, and probability.

This is a self-paced online course. It contains 10 modules, each with multiple lessons that support varied approaches to help a student learn and engage with the topic, including readings, video, and a knowledge-check quiz. This is a graded course, each student will receive a course transcript that reflects a final grade based on 10 module quizzes, 10 module evidence activities, a mid-term exam, and a final exam.
