Number Chart

The mathies interactive Number Chart tool includes two number charts (0-99 and 1-100), an addition chart (to 12 + 12), and a multiplication chart (to 12 x 12). Flip individual cards, rows, columns or all cards at once.

Number Chart Considerations

Mathematical Concepts:

Number charts offer versatile ways to explore numerous math skills such as:

Addition and multiplication charts provide opportunities for immediate feedback as students practise addition and multiplication facts. These charts can also be used to support students in developing and understanding various strategies for adding and multiplying.

Students’ learning can be scaffolded in different ways providing support for diverse learning needs (e.g., hide rows and columns to consider fewer cards).

Connecting Fundamental Math Concepts with the mathies Number Chart

Fundamental Concepts and Skills (Link #6) Number Chart Connections
Working with numbers:
Understanding and using numbers (e.g., being able to read, represent, count, order, estimate, compare, compose, decompose, and recompose numbers).
Number charts can be used to:
  • support students in numeral recognition
  • practise counting and skip counting
  • compare numbers by considering their relative position in the chart
Recognizing and applying understanding of number properties:
Understanding how numbers behave in operations and drawing on that understanding to master math facts and perform calculations.
Number and Operation charts can be used to:
Mastering math facts:
Understanding and recalling math facts, using a variety of strategies.
Operation charts are good tools to use to practise addition and multiplication facts.
Developing mental math skills:
Doing calculations in the mind, with little or no use of paper and pencil or calculator.
Using visual tools when learning to perform mathematical operations allows students to draw on these mental models and visualizations to perform mental calculations.
The Number Chart can be used to practise a variety of strategies including:
  • decomposing numbers into friendly numbers to make calculations easier
  • compensating by adding then subtracting the same amount
Developing proficiency with operations:
Performing calculations with ease, precision, and consistency and with a general understanding of number and operations, number properties, and their appropriate application in problem solving.
Students might use the operations charts to recognize the inverse relationship between addition and subtraction (e.g., since 4 + 5 = 9, then 9 - 5 = 4) as well as the inverse relationship between multiplication and division (e.g., since 7 x 8 = 56, then 56 ÷ 7 = 8).

Counting and Numeral Recognition

Number charts can be used to support students in developing counting and numeral recognition skills.

Activities Using the Number Chart from 1-100



Number charts can be used to create a range of patterns from simple AB patterns to growing or shrinking patterns as well as to really delve into multiples. Students can use the charts to help identify, extend, and create patterns.
