KNOWLEDGE IN EVERYDAY LIFEACCURACY AND SPEEDMENTAL MATH
A FEW IMPORTANT REMINDERS : - 1. Homework and correction work needs to be done on a regular basis. 2. Children must bring the materials for class activities (eg. straws, cut-outs etc.) when informed by the teacher. 3. A neat folder should be maintained for keeping the worksheets. 4. Notebook work must be followed up. 5. Regular revision of classwork must be encouraged in children.
