Students use virtual algebra tiles on their smartphones/computers to represent and manipulate algebraic expressions. They can model expressions like 3x + 2, x² + 2x + 1, etc. This helps visualize the relationship between geometric representations and algebraic expressions.

Website suggestion: Use platforms like Math Learning Center's virtual manipulatives.

Create a digital scavenger hunt where students solve clues that involve simplifying algebraic expressions. Each correct solution leads to the next clue. Students work in pairs using their devices to solve and verify answers.

Time: 20-25 minutes
Setup: Create a series of 5-7 connected algebraic puzzles

Use Desmos to create an interactive activity where students match equivalent expressions, complete card sorts, or create visual patterns using algebraic expressions. Students can work individually on their devices while teachers monitor progress in real-time.

Suggested activities:
- Matching equivalent expressions
- Creating visual patterns using functions
- Identifying errors in expressions

Organize students into virtual teams using breakout rooms or group chats. Each team member simplifies one part of a complex expression and passes it to the next teammate. The final student submits the completely simplified expression. First team to correctly complete the relay wins.

Time: 15-20 minutes
Group size: 4-5 students per team

Students use a simple coding platform or spreadsheet to create their own algebraic expression calculator. They must write formulas that evaluate expressions for different input values. This helps them understand how expressions work and variables change.

Tools needed: Spreadsheet software or basic programming platform
Duration: 30-40 minutes

# data[].attributes.body
Students create short videos (2-3 minutes) explaining how algebraic expressions are used in real-world situations. They can use their smartphones to record and include visual examples of the application.

Project components:
- Identify a real situation
- Write the algebraic expression
- Explain each term's meaning
- Demonstrate calculations

Using a digital classroom response system, create a competition where students simplify expressions against time. Points are awarded for both speed and accuracy. Include increasingly complex expressions as levels progress.

Platform suggestions: Kahoot, Quizizz, or Google Forms
Duration: 15-20 minutes

# data[].attributes.body
Students create digital posters showing step-by-step solutions to complex algebraic expressions. They then conduct a virtual gallery walk, commenting on their peers' work and identifying alternative solution methods.

Tools: Digital whiteboard or presentation software
Duration: 45 minutes (including creation and review)

# data[].attributes.body
Students use digital tools to create and illustrate stories where algebraic expressions play a central role. For example, a story about a shopping trip where items have variable prices, or planning a party with unknown numbers of guests.

Deliverables:
- Digital story with illustrations
- At least 3 algebraic expressions integrated into the story
- Solutions and explanations

Using digital spreadsheets, students investigate patterns in sequences of algebraic expressions. They must identify the pattern, write the general term as an expression, and predict future terms.

Activities include:
- Geometric sequences
- Number patterns
- Visual pattern sequences

Time: 30 minutes

Present students with incorrectly simplified algebraic expressions. They must identify the errors, explain why they're wrong, and provide the correct solution. Submit answers through a digital form or classroom platform.

Format: Individual or pair work
Number of problems: 5-8 expressions with common mistakes
