Year 2 Task Homework 27.2.20 Focus area: Topic Due to such wonderful feedback from the previous LEARN IT, KNOW IT, NOW USE IT document last half term we have decided to continue with the hope as the same effect the last one caused. This document contains the essential knowledge that children will need to know as part of the new topic they will be studying in class. These LEARN IT KNOW IT are designed to be used at home by parents to help children learn the information contained within. We want every pupil to be able to recall the information on these sheets off by heart by the end of the topic in other words LEARN IT KNOW IT USE IT. This knowledge will be tested in class at the end of every half term in the form of a quiz. We will also be learning the same information in class. The best way to use the LEARN IT KNOW IT USE IT at home is as follows – • Children read the information from the section to be learned (possibly with an adult) • They then try and recall the information (this can be written down or verbally) • An adult test (quiz) them on the information • The key to success is to repeat this regularly each week • It is also important to keep revising the information that has already been learned in previous weeks to keep it fresh in the memory. We are confident that these LEARN IT KNOW IT USE IT will help our children to develop knowledge on a wide range of topics and will significantly improve their vocabulary. We hope that you are able to support us in your child’s development. Yours faithfully, .
