For parents and teachers

Measuring means counting the spaces between marks, not reading the number at the end. The Not from zero level shows why: a pencil from 3 to 11 is 8 centimetres long, not 11. Use a real ruler at home with pencils and crayons, and ask your child to say both the start and end marks before giving the length.
