Math Conversions and Significant Digits Curriculum Overview

This document outlines the curriculum for the first four weeks of lessons focusing on math conversions and significant digits. Each week includes a "Big Idea," agendas for daily activities, journal prompts for student reflection, and summaries for key learning points. Specific topics addressed include safety procedures in laboratory settings, the importance of hypothesis formation, concepts of accuracy and precision, and practical applications of scientific notation. Students are engaged through labs, discussions, and reflections to deepen their understanding of mathematical concepts in science.
