JAIN VIDYA MANDIR SR. SEC. SCHOOLHOLIDAYS HOMEWORK

CLASS –IX

Dear ParentsIt is summer vacation time again, a time to relax as well as fruitfully occupy the children in various scholastic and co-scholastic areas. Keeping this in mind, our teachers have painstakingly designed interesting Projects/ Assignments for children to be completed during the summer vacation. This would encourage in- depth learning, strengthen concepts and prepare ground for improved academic output.As Parents, kindly motivate and lend support to your children and ensure that they will complete the given work well in time and to the best of their ability. Your encouragement can actually make a huge difference to the ultimate learning outcome of these projects.Happy Holidays!
