Download PDFTo read the chart, find one factor in the column on the left and the other in the row across the top. The cell where that row and column meet is the product. For 27 × 23, go to row 27 and move across to column 23: 621.
A chart to 30 goes past the 12 × 12 facts students memorize. It is a reference for two-digit multiplication, for checking long multiplication and division, and for finding factors: every place a number appears in the grid is a pair of factors for it. A heavier line every five rows and columns helps the eye stay on the right row.
The chart also covers the facts behind everyday conversions: 24 hours in a day, 30 days in a month, 12 inches in a foot. Squares up to 30 × 30 = 900 run down the diagonal and are shaded yellow on the color chart.
For the standard sizes (10 × 10, 12 × 12, 15 × 15, 20 × 20) and single times tables, see the main multiplication chart page, or the slightly smaller 1-25 chart.
