In this lesson students will practice computing the average or mean of 3 or more menu prices or numbers with decimals.

In Module 1, student's understandings of the patterns in the base ten system are extended from Grade 4's work with place value to include decimals to the thousandths place. In Grade 5, students deepen their knowledge through a more generalized understanding of the relationships between and among adjacent places on the place value chart, e.g., 1 tenth times any digit on the place value chart moves the digit one place value to the right. Toward the module's end, students apply these new understandings as they reason about and perform decimal operations through the hundredths place.

In Module 4, students learn to multiply fractions and decimal fractions, and begin working with fraction division. Topic A opens the 38-day module with an exploration of fractional measurement. Students construct line plots by measuring the same objects using three different rulers accurate to 12 , 14 , and 18 of an inch.

In this activity, students will visit six stores by clicking on each store name. Each store will have a different scenario in which students will have to calculate an amount based on the question. Students will first estimate the answer, then give the actual solution. Students are to round answers to the nearest cent.  

Solving practical problems involving decimals Mathematics Instructional Plans (MIPs) help teachers align instruction with the Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.
