These houses are great for helping students recognise hundreds to thousands in Place Value. I've used these multiple ways.
1. In centres, I laminate them and students roll a dice to create largest number and then have to write in word form.
2. I have also used as a display. Students write numbers into the places, write in word form, glue onto A3 card and display around the room as a visual reference.
3. Target Number Template (similar to centre)
4. Have houses with numbers pre-written into for students to work on saying the number in word form and then sort.
