This is a type "B" Set. " Beginner A" Sets and "Beginner B" sets are the same size (Weight/Volume). The "B" sets are chunkier, have fewer small pieces and more big pieces. They lack the detail possible with the "A" sets, but are good in a setting where fewer shapes are helpful (for putting away) or where the age of the child (younger) suggests simpler designs. You can always add additional pieces later.
