This 9 block set shows each of the 8 moon phases plus one bonus block devoted to the lunar eclipse. Two debossed sides feature a moon phase and its cycle location. Four printed sides reveal moon rise & set times, tidal effects, a phase illustration, and the moon's location in relation to the sun. Open-ended building tools such as blocks serve a variety of purposes in the classroom. Blocks encourage children to build, stack, and arrange in many ways. Kodo's curated collections of Uncle Goose Blocks also support language and literacy development through letter shapes, illustrations, words, and symbols.
