Objective

By the end of this lesson, Steph will understand the relationship between litres and millilitres, and will be able to convert between the two measurements confidently. Steph will also engage in fun activities that reinforce these concepts through hands-on practice.

Materials and Prep

• Measuring cup (preferably with both litre and millilitre markings)
• Water (or any liquid for measuring)
• Empty bottles or containers
• Paper and pencil for notes
• A timer (optional for timed activities)

Before the lesson, ensure that the measuring cup is clean and that Steph understands the basic concept of volume.

Activities

• Measuring Challenge: Steph will fill the measuring cup with water to see how many millilitres are in one litre. This hands-on activity will help her visualize the difference in volume.
• Container Comparisons: Using various containers, Steph will estimate and then measure how many millilitres they can hold, comparing them to a litre.
• Conversion Game: Create a fun game where Steph converts litres to millilitres and vice versa. For example, if she has 2 litres, how many millilitres is that? (Hint: 1 litre = 1000 millilitres!)
• Water Art: Using the water from the measuring cup, Steph can create art by pouring different amounts into various containers, labeling them with their measurements in litres and millilitres.

Talking Points

• "Did you know that 1 litre is the same as 1000 millilitres? That means if we have 2 litres, we have 2000 millilitres!"
• "When we measure liquids, we often use litres for bigger amounts and millilitres for smaller amounts. Can you think of something that might be measured in millilitres?"
• "Let’s see how many millilitres are in this container together! Remember, we can always use the measuring cup to find out!"
• "If I say I have 500 millilitres of juice, how many litres is that? That’s right, it’s half a litre!"
• "Why do you think it’s important to know how to measure liquids? It helps us in cooking, baking, and even mixing drinks!"
• "Can you think of a time when you’ve used a measuring cup? Maybe when helping in the kitchen?"
• "Let’s play a game! I’ll give you a number in litres, and you can tell me how many millilitres that is. Ready?"
• "Great job today! Remember, measuring is not just about numbers; it’s about understanding how much of something we have!"
