Help students make sense of place value with our Expanded Form Look & Write PowerPoint. This interactive activity supports learners in recognising how numbers are built by combining hundreds, tens and ones - a key skill for understanding number structure and value.

Each slide presents a number in expanded form. Students read the expression (e.g. 300 + 40 + 2), then write the matching numeral using a whiteboard, paper or book. The next slide reveals the correct answer, allowing students to check their thinking and refine their strategies.

Expanded Form Look & Write PowerPoint is ideal for warm-ups, small group instruction, or whole-class modelling during your place value unit.

Key Learning Outcomes:

• ✅ Read and interpret numbers written in expanded form
• ✅ Convert expanded form to standard numerals
• ✅ Strengthen understanding of place value and number composition

What’s Included:

• Interactive PowerPoint with 20 expanded form slides
• Each sequence follows the LOOK - WRITE - CHECK format
• WRITE slides can be removed to run the activity orally

Materials Needed:

• Interactive whiteboard or device capable of running PowerPoint
• Optional: small whiteboards to use for extra hands-on learning

How to Use:

1. Open the PowerPoint on your interactive whiteboard or device.
2. Display each expanded form and give students time to read it.
3. Students write the corresponding numeral on a whiteboard, paper or in their book.
4. Click to reveal the correct number and discuss the place value components.
5. Repeat to reinforce fluency in reading and writing numbers in different forms.

Ideas for Classroom Use:

• 💡 Use during your place value unit as a warm-up or review task
• 💡 Include in maths rotations for independent or small group practise
• 💡 Pair with base ten blocks or place value charts for hands-on support
• 💡 Use orally with partners or small groups by removing the WRITE slide
• 💡 Extend by asking students to write the expanded form for the answer as well

Top Teacher Tips:

• 💛 Use small whiteboards so students can quickly record and adjust their answers
• 💛 Reinforce the place value vocabulary (hundreds, tens, ones) throughout the activity
• 💛 Use the slides as exit tickets or mini-assessments to check student understanding

Expanded Form Look & Write PowerPoint is a practical, engaging tool for deepening students’ understanding of number structure - helping them build strong place value foundations through hands-on, interactive practise.
