Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.

Activity 1

Decimal Pantry Shopping Spree

Students create a shopping list for their dish using simulated purchases from a virtual pantry, applying decimal addition for budgeting.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Introduce the concept of a virtual pantry where each item has a price in decimal form.

2. Have students choose a dish they want to make, based on a provided list of recipes that use decimals in measurements.

3. Ask students to 'purchase' ingredients using decimal prices from the pantry, writing the total cost using decimal addition.

4. Ensure students adjust their shopping list based on a set budget, practicing subtraction of decimals to stay within budget.

Final Product

What students will submit as the final product of the activityAn itemized shopping list with a calculated total cost using decimal addition and subtraction.

Alignment
