Patterns in the hundreds chart
Down a column every number grows by ten; along a row, by one. Filling in missing numbers makes children use those patterns instead of counting from 1 every time.More counting

- Primary 1Numbers up to 100, place value in tens and ones, and patterns in number sequences.
- Primary 2Counting in tens and hundreds, numbers up to 1000, and odd and even numbers.
- K1–K2The NEL Framework expects counting to at least 20, so the first two rows are enough for most preschoolers.
Singapore’s Primary 1 syllabus stops at 100, so the 1 to 100 chart covers the whole P1 number range. The 1 to 120 option goes further than the syllabus asks and suits children who are ready for more.
P1 children also add and take away tens mentally, which is one step down or up a column. In Primary 2, use the chart for odd and even numbers: colour every even number and talk about the columns that appear.
