📹 Video Lesson Tips

Watch the video and get the most out of it:

• 👉 Use real objects like small water bottles, milk cartons, and measuring jugs
• 👉 Encourage students to predict first, then measure with a jug or container
• 👉 Ask children to compare capacities using phrases like:
  • 🧴 “This bottle is about half a litre”
  • 🐟 “The fish tank is about 3 times the milk carton”

• 👉 Add simple visual labels on containers (“500 mL”, “1 L”) to reinforce learning 🏷️
