Module 8  Math 4B  Course Guide
Module Overview:
In this module, students will learn about comparing decimals using area models, decimal circles, and number lines. They will learn about comparing decimals and deciding if a comparison is reasonable. Students will learn about equivalent measurements of length and measuring with customary units of length. Students will measure with inches, feet and yards and learn how to convert between the different types of measurements. Students will estimate length measurements. Students will learn about measuring weight and mass. They will learn about using tables to represent equivalent measurements of weight. Students will learn about converting units of weight. They will learn about problem solving and estimating weight.
