Early Homework aims to make homework a positive learning experience, reinforcing core subjects (English, maths and science) and cross-curricular thinking skills, through enjoyable practice activities. Pull-out answers make marking quick and easy and give children the chance to evaluate their own progress. Book 4 supports the Primary National Strategy for literacy and mathematics and the National Curriculum for science at KS1, including: literacy - reading comprehension/verbs and adverbs/rhyme/descriptive language, maths - using a hundred square/tens & units/vertical addition & subtraction of 2-digit numbers (with carrying & borrowing)/addition with one number hidden/rounding/multiples, science - electricity/forces and movement/light and sound/seasonal changes.
