MODULE 4
In Module 4, students learn to multiply fractions and decimal fractions and begin working with fraction division.
Topic A opens with an exploration of fractional measurement. Students construct line plots by measuring the same objects using three different rulers accurate to 1/2 , 1/4 , and 1/8 of an inch. Students compare the line plots and explain how changing the accuracy of the unit of measure affects the distribution of points. Students use their knowledge of fraction operations to explore questions that arise from the plotted data. Topic B focuses on interpreting fractions as division. Equal sharing with area models (both concrete and pictorial) provides students with an opportunity to understand division of whole numbers with answers in the form of fractions or mixed numbers (e.g., seven brownies shared by three girls, three pizzas shared by four people). Discussion also includes an interpretation of remainders as a fraction. Tape diagrams provide a linear model of these problems.
