More alphabet work! To increase understanding in using a dictionary why not try the following?
Ask the children to write the letters of the alphabet down the page and find a word starting with each letter in the dictionary and write it on their page. Encourage them to look for new words. Once they are finished, move the lists between children so they can check the spellings in the dictionary. Get children to read out the meanings of the words they find interesting. Take a vote on which is the most interesting new word that has been found.
This idea is from Sentence Level Work in the Brilliant Support Activities series. The book contains 42 photocopiable worksheets for Key Stage 2 (KS2) pupils who are working at levels consistent with the first four years of the National Literacy Strategy document. They introduce one concept per sheet, and provide additional practice and support for those children who are struggling to learn concepts and skills first introduced at Key Stage 1.
