Five wooden activities in one compact cube — music, time, gears, shapes and a bead maze.

The Pentagonal Logic Hub is a 5-in-1 wooden activity cube: a xylophone, a learning clock, turning gears, a shape sorter and a bead maze on top. Each side asks for a different kind of thinking, so toddlers can move from one challenge to the next at their own pace.

The Iconic Standard

Made from wood with water-based paint and smooth, rounded edges. The manufacturer states the cube meets ASTM requirements. Every order ships free, with an estimated 4–12 business-day delivery to the US.

📐 FIVE ACTIVITIES

  • Xylophone: tapping out high and low notes.

  • Learning clock: turning the hands to explore numbers and time.

  • Gears: seeing how one turn moves another — early cause and effect.

  • Shape sorter: matching blocks to holes to practise shapes and the pincer grip.

  • Bead maze: guiding beads along the wires for hand–eye coordination.

📦 FLIP-TOP STORAGE

  • Lift the bead maze off, flip it and set it back on the cube: the top becomes a flat play surface and the inside stores the sorter blocks. Tidy-up becomes part of the game.

🌳 WOOD, NOT PLASTIC

  • Warm-to-the-touch wood, bright colours and a solid, weighty base that stays put during play.

🧠 INDEPENDENT PLAY

  • In the Montessori spirit, the Hub offers several self-directed challenges in one place, encouraging longer, focused play.

🚚 FREE SHIPPING & 30-DAY RETURNS

  • Every order ships free. Orders are processed within 1–2 business days, US delivery takes an estimated 4–12 business days, and tracking is emailed as soon as your Pentagonal Logic Hub ships. Not the right fit? You have 30 days from delivery to return it.

⚠️ SAFETY NOTE

  • Adult supervision recommended. Check the cube and blocks regularly and stop using any part that is loose or damaged.

Frequently Asked Questions

Q: Is the xylophone tuned?

A: It is a toy xylophone: each bar gives a clear, distinct note for exploring high and low sounds, but it is not a concert-tuned instrument.

Q: Does the storage hold all the shape-sorter blocks?

A: Yes. The inside of the cube holds all the included sorter blocks, so cleanup is one lid away.
