How generation works

  • Each pyramid is built from random bottom numbers, then summed upward row by row.
  • Difficulty controls how many values are blanked while keeping each row solvable.
  • Large cells mode limits to four puzzles per page for bigger handwriting space.

What you’ll get

The preview matches the PDF layout, so you can check spacing and readability before you print or download.

About number pyramids

Number pyramids (also called addition pyramids) build arithmetic fluency by reinforcing sums and number patterns. Students solve from the base upward, filling each block with the sum of the two blocks below.

Use easy mode for quick warm-ups, medium for guided practice, or hard for deeper reasoning. The printable layout keeps spacing consistent for clean handwriting and quick grading.

A quick note

Worksheets are generated in your browser and can vary slightly based on settings. Printing results depend on your printer and margins.

How it works

Each puzzle starts with random bottom numbers, then sums upward to create the full pyramid. Difficulty controls how many values are removed before printing.

Rules summary

  • Each block equals the sum of the two blocks beneath it.
  • The bottom row has N numbers (4 to 8).
  • Blank cells are left for students to solve.

PDF layout

  • A4 portrait with clean margins.
  • Two columns per page for consistent spacing.
  • Optional solutions page mirrors the puzzle layout.

Try this quick example

  1. Set rows to 4 or 5 for a short warm‑up.
  2. Choose Easy difficulty for more given numbers.
  3. Generate 6–8 puzzles for one class set.
  4. Enable solutions if you want an answer key.

Tips for better pyramids

  • Start with fewer rows for new learners.
  • Use medium difficulty to balance practice and confidence.
  • Print at 100% scale for consistent cell sizes.

Limits to keep in mind

Larger row counts can make cells smaller on paper. If handwriting feels cramped, reduce the row count or enable large cells mode for more writing space.

FAQs

Quick answers

What is a number pyramid?

A number (addition) pyramid is a triangle where each block equals the sum of the two blocks beneath it.

How does difficulty work?

Easy keeps more givens, medium removes more values, and hard blanks the most while keeping every row solvable.

Can I include solutions?

Yes. Turn on the solutions toggle to add a second page with all values filled in.

What does large cells mode do?

Large cells mode increases writing space and automatically limits the PDF to four puzzles per page.
