Plus-Plus Hearts Block puzzle 250 pieces — plus plus — Shapes set for ages 7–12

Plus-Plus Hearts Block puzzle 250 pieces is a Shapes construction set from plus plus designed for children aged 7–12. The kit contains 250 interlocking heart-shaped blocks that click together to form flat mosaics and basic three-dimensional shapes. This set combines guided pattern work with open-ended construction: follow the included Puzzle By Number® pattern to place colored hearts according to numbered positions and create a finished design, or use the pieces freely to build original mosaics and simple models. No glue or ironing is required, and finished works can be displayed on a table or hung as room décor.

Advantages

The heart-shaped blocks are uniform in size and compatible with other plus plus pieces, allowing smooth connections and easy assembly for children. The Puzzle By Number® format offers a clear step-by-step activity that supports concentration and visual matching skills while the unstructured play option encourages creativity and problem solving. The 250-piece count provides enough variety to build recognizable patterns or multiple small projects, suitable for solo play or small group activities in home or classroom settings.

Suitable for

• Guided craft activities and step-by-step creative projects
• Freeform mosaic art and simple 3D constructions
• Developing fine motor skills and hand-eye coordination
• Classroom lessons on pattern recognition and spatial reasoning

Key specifications

How to use

Open the kit and sort pieces by color if desired. Follow the enclosed numbered pattern to place each colored heart block into the correct position for the Puzzle By Number® design, or assemble pieces freely to create custom mosaics and models. Press pieces together firmly until they click; for flat mosaics work on a stable surface and for simple 3D builds start with a solid base. Finished pieces can be set on display or hung on a wall without glue or heat treatment.

Usage recommendations

Supervise younger children during play and store pieces in a secure container after use to prevent loss. Combine this set with other plus plus kits for expanded color and construction possibilities. Use a flat, well-lit workspace for pattern work and encourage gradual progression from following the Puzzle By Number® design to independent creative building.
