Zero as a Placeholder - Poster
The Zero as a Placeholder Poster helps students understand the critical role zero plays in our number system.
With simple explanations and illustrated examples like:
• 402 is not 42
• 507 is not 57
• 620 is not 62
…the poster clearly shows how zero holds the correct place in a number, ensuring that each digit has the correct value.
Perfect for your maths wall, number of the day lessons, or numeracy warm-ups.
Learning goals
- We are learning to read, write, name and order two-digit numbers to at least 120 using concrete materials, hundred charts and number lines.
- We are learning to read, write, name and order numbers to at least 1000 using concrete and virtual materials, numerals and number lines.
- We are learning to read, write, model and represent numbers to 100 in different ways and on number lines.
- We are learning to recognise, model, represent and order numbers to at least 1000.

Differentiation
Modifications
• Provide mini versions for student notebooks or maths folders.
• Use alongside hands-on base-ten blocks or place value charts.
• Create an interactive version where students insert digits and see what happens when zero is removed.
Extensions
• Ask students to invent number stories where forgetting the zero changes the meaning.
• Use as a warm-up prompt: “What happens if we take the 0 away from this number?”
• Have students build numbers with missing digits and fill in the placeholder.
