Wooden Montessori Puzzle Blocks Colorful Tangrams Sorting and Stacking Jigsaw STEM Early Learning Travel Game Educational Gift for Kid Toddlers Boys Girls Age 3+(120 Pieces and 60 Cards in Iron Box)

How the pieces all interlock perfectly with one another. Putting them on a pattern sheet. The shapes are designed perfectly sized so that two trapezoids are the same size as the hexagon and you can put the triangle together to make a trapezoid or a hexagon. Children learn what shapes can be combined to make the bigger shapes, so they also work well to teach fractions. Let them sort them by shape and color and make patterns (repeating shapes and colors). In small groups, I model fitting the shapes together for them and let them experiment with covering a surface with shapes. The box comes with a few example pattern cards for ideas. Made of real wood and the paint on all of mine were great, not chipped. The paint did not chip off during play either. You can stack them to make shapes or lay them down. Endless possibilities to make beautiful patterns and works of art. Helps teach children three and older matching and sorting skills, color recognition, geometric shapes, counting, and beginning math skills. Fitting the pieces helps develop fine motor skills, problem-solving skills, concentration, and memory. Wooden pattern blocks Lots of fun building patterns with different levels of skill. Wooden pieces and plenty of variety for 2-3 kids to be building at the same time. After done using the cards for patterns, children can use their imaginations and create a whole array of things. A great value. It makes fascinating designs. With older students, invite them to try to figure out which shapes will fit together. After that introduction, have them make tessellations.
