Weighing is a practical topic so if you can manage at home to get some practical experience of using and reading scales this would be a great! Talk about words such as heavier and lighter, and grams (g) and kilograms (kg). Discuss how there are 1000g in 1kg. Have a go at the investigation to estimate and weigh objects heavier or lighter than 1kg. There are also some videos, PowerPoints, games and worksheets to get you thinking about measuring weight. Why not have some fun baking cakes or buns and weighing out all the ingredients!!!
