Engaging Introduction to Decimals and Place Value

Lesson Title: Decimals Unplugged!

Grade Level: Year 7
Subject: Mathematics
Topic: Decimals and Place Value, Adding and Subtracting Decimals

---

Lesson Hook: "The Great Shopping Challenge"

Objective

To engage students in understanding decimals and place value through a fun and relatable scenario.

What You Need

• Items for Sale: A selection of “virtual” shopping items with prices written in decimals (e.g., $3.75, $12.50, $0.99).
• Play Money: Stack of paper notes or fake banknotes.
• Whiteboard or Smartboard: To track group findings.

Introduction Activity

1. Setting Up the Scenario: Begin the lesson by telling students they are part of a "Grocery Store" where they will be responsible for purchasing items for their team. Showcase exciting images of a grocery store filled with various products (or if possible, set up a mini store in the classroom).

   Example Explanation:

   “Today, we are going to delve into the world of decimals! Imagine you are in a supermarket where soft drinks are $1.20, snacks are $2.99, and fruits are $3.75. Your challenge is to buy as many items as you can with a budget of $15.00. But there's a twist – you must keep track of the total you spend using addition and subtraction of decimals!”

2. Group Formation: Divide students into small groups of 3-4. Distribute fake money and a list of items with associated prices.

3. Challenge Instructions: Each group will have 10 minutes to decide which items to "purchase" while keeping track of their spending in a simple budget calculator they will create. Ask them to practice adding and subtracting decimals from their total budget.

4. Tracking Total: Have groups write down their items and calculate the total spent, ensuring they practice decimal addition and subtraction. If they go over their budget, they will need to adjust by removing items and subtracting their costs.

Post-Activity Discussion

Once the challenge is completed, gather the class for a discussion. Ask:

• "What strategies did you use to make sure you stayed within budget?"
• "How did you add and subtract the decimal amounts?"
• "What did you find easy or challenging about using decimals?"

Transition to Lesson Content
