KS2 English Writing Buster - Handwriting by CGP Books
This book is an excellent source of joined-up handwriting practice for Key Stage Two pupils (ages 7-11). For each letter of the alphabet, there's a big selection of sentences to copy out - all packed with practice at joining that letter to others. There's an example at the top of each page to remind children how to make the join, plus fun pictures and rhymes to help keep them motivated.
