"Shape Worksheet Maker" automatically generates printable shape worksheets for Japanese elementary school entrance exam prep (小学校受験) and early-grade learners. With a single tap, create fresh problem sets in the topics where children most often struggle—and never run out of practice. Six problem types are included: dot-grid line symmetry, dot copying, 90° rotation, find-the-same-shape, top-down views of stacked blocks, and paper-folding hole problems. Every print is freshly generated, so children can repeat the same topic without seeing the same questions twice. Designed for home study, classroom prep, tutoring centers, mock-exam practice, and private elementary school entrance exam (小学校受験) paper-test preparation. Preview each worksheet in the app, then save as PDF, print, or share—no manual layout work or hand-drawn problems required. Ideal for parents whose children need more drill practice than commercial workbooks provide, and for teachers who want to cut prep time without sacrificing quality. [Problem Types] • Line symmetry on a dot grid: mirror the sample figure across the center line • Dot copying: trace and reproduce a figure on a fresh dot grid • Rotation: pick the figure rotated 90° clockwise • Find-same: spot the identical figure among carefully designed lookalike distractors • Top-down view of stacked blocks: choose the correct overhead pattern • Paper-folding holes: predict the unfolded pattern after punching holes More problem types are planned in future updates. [Main Features] • Auto-generate worksheets (always fresh problems) • Configurable layout (1–3 columns) and problem count • A4 portrait auto-layout • In-app preview before printing • Save as PDF, print, or share • Auto-fill date • Custom header: school name, class name, name field • One-tap reprint from history [Free Trial] After downloading, the first 3 worksheets are free to create, save, and print (lifetime trial, not a daily reset). If you find it useful, upgrade to Pro for unlimited use and the full feature set. [Pro Subscription] Upgrade to Pro for unrestricted access to every feature: • Unlimited worksheet creation and printing • Advanced problem types unlocked (top-down blocks, paper folding) • Answer-sheet generation • Ad-free experience • Header printing of school and class name • Unlimited history with one-tap reprinting • Early access to upcoming Pro-only features Recommended for teachers who use the app continuously in class or tutoring, and for families seriously preparing for entrance exams.
