A Gattegno chart is a table of numbers with columns representing a different power of 10 and rows representing multiples of powers of 10. These charts are a fantastic tool to use with learners to build understanding of our base 10 number system and in teaching maths for mastery. The visual nature of these charts aids in the comprehension of abstract mathematical concepts, making them more concrete and understandable. Gattegno charts can be adapted for learners of all ages and for various mathematical concepts, including place value, multiplication and division, fraction and decimal operations, and finding percentages of amounts.

Introduce pupils in Key Stage 1 to Gattegno charts by using them to count including skip counting. This approach helps build awareness of number patterns and relationships. As learners progress, Gattegno charts facilitate the construction and partitioning of large numbers. Related facts can be derived, such as understanding that if 2 + 7 = 9, then 200 + 700 = 900.

At Key Stage 2 we at Cazoom have used Gattegno charts to multiply and divide integers and decimals by powers of 10 and our range is ever growing. Below is our range of KS1 and 2 resources utilising Gattegno charts.

### What are Gattegno charts in maths?

Gattegno charts are visual tables that illustrate our base-10 number system. They have columns representing ones, tens, hundreds, and so on, with rows showing multiples of ten. These charts help students grasp place value, identify number patterns, and understand how to multiply and divide by powers of ten. Gattegno charts make abstract maths concepts more concrete, aiding comprehension and building a strong foundation for mathematical thinking.

### importance of gattegno charts

Gattegno charts are vital tools in maths education because they turn abstract numerical concepts into clear visual representations. These charts illuminate place value by organizing numbers in columns (ones, tens, hundreds, etc.) and rows (multiples of ten). This structure reveals patterns and makes operations like multiplication and division by powers of ten easier to understand.

For example, students can visually see that 300 is ten times larger than 30. Gattegno charts build a strong foundation for mathematical thinking and more advanced skills.

### uses of Gattegno CHarts

Although primarily an educational tool, the principles of Gattegno charts can find subtle uses in daily life. For instance, converting between metric units (like kilometers to meters) mirrors the decimal place shifts emphasized on the chart. Budgeting might be easier when thinking in multiples of ten, a habit Gattegno charts promote. Time calculations can also benefit – figuring how many minutes are in three hours might be aided by a mental model of the chart. Even scaling recipes up or down, which involves multiplication and division, aligns with skills practiced with Gattegno charts.
