Build it with materials first
Use bundles of ten straws, base-ten blocks or coins so 'ten ones make one ten' is something a child physically does, not just hears. Group ten, swap for a ten, and write the number alongside.
Name the columns
Introduce ones, tens, hundreds as columns on a place-value chart. Show that 247 is 2 hundreds, 4 tens and 7 ones, and have children build numbers you call out and read back numbers you build.
Common mistakes
- Reading 207 as 'twenty-seven' (ignoring the zero placeholder).
- Thinking the bigger digit is always worth more, regardless of column.
- Lining numbers up by the left instead of the ones column when adding.
