What's inside (36 pages)

• 30 Target puzzles: reach the number with + − × ÷ using six numbers (10 easy, 10 medium, 10 hard)
• 60 Cage Grids: 20 each of 4×4, 5×5 and 6×6. Fill the grid so every row and column has each number once and every cage makes its clue. Each one has exactly one solution, checked by a solver program.
• 30 Brick Pyramids: each brick is the sum of the two below it; hard ones need algebra-style thinking
• Full answer key, a how-to-play page with worked examples, and page numbers for easy assigning
• US Letter and A4 PDFs, crisp vector pages that print well in black and white
• puzzles.json: every puzzle and solution as data

Made for morning work, early finishers, math centres, sub plans and enrichment (about grades 3–8 and up), homeschool, tutoring, travel and puzzle lovers of any age.

Pricing: $5 one-time, about 4 cents a puzzle, with classroom copies included. Need it for a whole school? The School Licence is $19.

FAQ

• Can I print it for my class? Yes. One teacher may print and photocopy unlimited copies for their own students, every year.
• Why not free worksheets? Free sheets are fine for a one-off. This book is three puzzle kinds in one consistent, levelled, print-ready design with every answer and a licence that covers your classroom, so there's nothing to assemble.
• Why not a 400-puzzle book? Big single-kind books repeat one skill. This one mixes arithmetic, logic and early algebra, levelled easy to hard.
• Are the puzzles original? Yes, every one was generated and checked by our own puzzle programs, the same family as Sumbloom, the free daily number puzzle.
