Review on Coogam Wooden Pattern Blocks - Tangram Shape Puzzle Set for Kids - Color Sorting Stacking Game - Montessori Brain Teaser - STEM Gift for 3 4 5 Year Old Toddler - Includes 60 Pattern Cards by Matthew Gonzales

I bought these as a gift but checked before giving as a gift. This is such a fun concept for kids ages 3 and up. They can be used for their intended purpose, with cards as a guide, or in free play. All parts were included in our kit - no quality defects. My main complaint is that the forms come from one bank and the cards come from another bank. I wish it was designed to hold the two together. Two separate cans are more risky to lose/separate and also make work/storage/travel more difficult.
