Students link together the rods in this set to build simple, compound, and complex sentences in English. There are 123 colour-coded sentence building blocks which include adjectives, articles, adverbs, prepositions, punctuation symbols, verbs, nouns, pronouns, conjunctions and spaces. The rods are easy for little hands to snap together as they build short and long sentences. The 123 colour-coded rods are in a box with dividers for organisation and includes a Teacher’s Guide with free downloadable content.
