## The Geddes School Store Lesson Plan Library

Welcome to the Geddes library of school store lesson plans. Here you will find our collection of math-based lesson plans educators can use to extend student learning beyond the classroom and into the interactive environment of a school store.

Each lesson is tailored to a specific learning activity appropriate for 3rd to 5th grade level mathematics. Teachers are guided through lesson materials that have been modeled around established curriculum standards of the National Council of Teachers of Mathematics (NCTM), as well as employing learning methodologies outlined in Bloom's Taxonomy of Educational Objectives.

### What's on Sale?

Lesson Length: Approximately 2 days

Learning Objectives

• The student will calculate sale prices based on 10%, 25%, 50%, and 75% price reductions.
• The student will demonstrate proficiency using a calculator to calculate new sale prices.
• The student will recognize that percentages can also be stated as decimals and fractions.

### Charting and Graphing Sales

Lesson Length: Approximately 2 days

Learning Objectives

• The student will analyze and represent weekly sales figures using tables, bar graphs, and pie charts.
• The student will draw conclusions using bar graphs and pie charts.

### Measuring Angles

Lesson Length: Approximately 2 days

Learning Objectives

• The student will analyze and measure angles using a protractor.
• The student will identify angles as right angle, acute angles, and obtuse angles.
• The student will build and draw right, acute, and obtuse angles.

### Estimating School Store Purchases

Lesson Length: Approximately 2 days

Learning Objectives

• The student will identify appropriate uses for estimation.
• The student will round purchase prices to estimate total purchases in a school store setting.
• The student will practice estimating by using rounding and mental computations to arrive at estimates.

### Paying with Coins

Lesson Length: Approximately 2 days

Learning Objectives

• The student will identify various ways to represent the same dollar amount using coins.
• The student will pay for items using coins of various denominations and in multiple combinations to arrive at the same total amount.
• The student will propose purchase options given an allotted amount of money (budget) to make those purchases.

#### R.G.'s Literary Connection

Geddes lesson plans help introduce mathematics as they relate to a school supply store scenario. Expand on the lesson by visiting R.G.'s bookshelf. In each lesson plan, R.G. refers students and teachers to related reading material and links to where the book can be purchased.

#### Sniffer's Vocabulary List

Who knew dogs could have such an extensive vocabulary? (Or add and subtract, for that matter!)

Each lesson brings up words and terms that students might not have heard before. Sniffer helps readers expand their vocabulary by introducing new words and connecting the meaning to their application within the mathematics lesson.

#### Word Origins by Hannie

We use words like percent and estimate all of the time. But where do these words come from? Turns out that math has a lot of history in it too. Hannie takes words introduced in each lesson plan and shines a light on their basic roots so students can see where it all began.

#### Bloom's Taxonomy

We start out each lesson plan by showing exactly how the lesson ties in with established teaching methods detailed in Bloom's Taxonomy of Educational Objectives.
