• Use place value charts or grids for visual support

• Break numbers into expanded form (e.g., 45,678 = 40,000 + 5,000 + 600 + 70 + 8)

• Provide number lines for rounding support

• Create your own 7-digit numbers and challenge a partner

• Investigate negative numbers and decimal place value

• Research how place value works in other number bases (binary, base 5)

• Design a place value game using playing cards

• Use coloured overlays or different coloured pens for each place value column

• Break large numbers into chunks of three digits

• Provide audio recordings of number names for reference
