Periodic table blocks are an ingredient list of the world around us. This 20 piece block set is an interactive way to learn the names of the elements, their two letter associations, and atomic number. Younger age groups will absorb the scientific vocabulary through the exposure of stacking and building with the 1.75" Michigan basswood cubes. Older children will utilize more advanced recall and recognition skills to commit the periodic table to memory! This durable block set from Uncle Goose will add value to your child's education as they grow. Suitable for ages 2+.
