The Number Chart block creates a customizable number grid (like a hundreds chart) with options for hidden cells, highlighted cells, and custom coloring. Use it to explore number patterns, skip counting, and place value. This is a display block for teaching and demonstration. Learners can view the chart but aren’t assessed on it.
For assessable activities where learners fill in missing numbers or identify patterns, use the Number Chart Question block instead.

​
When to use Number Chart blocks

Number Chart blocks work well for:
  • Displaying a hundreds chart (or any number range)
  • Highlighting skip counting patterns (2s, 5s, 10s)
  • Showing odd and even number patterns
  • Hiding specific numbers for discussion and prediction
  • Teaching place value and number relationships
  • Exploring number sequences with custom step values

  • Highlighting cells: Add a highlight color to draw attention to specific numbers
  • Coloring cells: Apply custom colors to individual cells to show patterns

Tips for teachers and parents

Best practices:
  • Use a standard 10x10 grid starting at 1 for a classic hundreds chart
  • Highlight multiples of a number (e.g., every 3rd cell) to show skip counting patterns
  • Hide cells to create prediction activities (“What number should go here?”)
  • Change the start number and step to create charts for different number ranges
  • Use Snake direction for number line-style displays
  • Try a 1x10 grid for a simple number line layout
  • Color-code groups of numbers to show patterns like odd/even
