Number Fluency Module Overview Title

Introduction

Suppose you were having to raise money for your club at school, so you and your friends decided to have a bake sale. Some students brought brownies, some bought cookies, and a few brought chips. Is there a way to figure out how to make baggies containing brownies, cookies, and chips with all bags being equal and without having any left-overs? The answer is YES! In this module you will find out how to divide groups (numbers) into equal partitions. You will also be reminded how to multiply and divide decimal numbers. You can use this when you are asked to do a job at home you can calculate how much you are owed!
