Cateam Montessori Brain Blocks for Kids - Wooden Stacking Puzzle with Numbered Tray 1-10, 42 Pieces in 9 Shapes, 10 Grid Cards with 20 Challenges - Russian Block Brain Teaser STEM Gift Ages 3-6

Cateam Montessori Brain Blocks for Kids - Wooden Stacking Puzzle with Numbered Tray 1-10, 42 Pieces in 9 Shapes, 10 Grid Cards with 20 Challenges - Russian Block Brain Teaser STEM Gift Ages 3-6

• GRID CARDS THAT MATCH THE BOARD: Every challenge card is printed on a 10-column grid numbered 1-10 that lines up with the engraved tray, so a child sees exactly where each piece goes and finishes a build without adult help.
• 20 CHALLENGES ON 10 DOUBLE-SIDED CARDS: Flip a card over for a harder build - beginner patterns on one side, expert on the other. Kids 3-6 move up at their own pace, so the set still gets played months later.
• 42 PIECES IN 9 SHAPES, DRAWN SQUARE BY SQUARE: Each shape on the card is split into visible cube squares, so a 4-year-old counts cubes and matches by size instead of guessing. Smooth edges and child-safe non-toxic paint.
• SCREEN-FREE FOCUS AT THE KITCHEN TABLE: This wooden brain teaser builds spatial reasoning, counting, patience and fine motor control - a quiet activity for homeschool, preschool, road trips, waiting rooms and therapy sessions.
• STANDS UPRIGHT, PACKS AWAY FLAT: The board rests on its own wooden stand and measures 12.3 x 7.8 x 0.5 inches, so it fits a shelf or a backpack. Everything returns to the printed gift box - ready to give, nothing lost.
