✨ Units of Weight
Alright class, let's get our minds working with measurements! To start, I want you to think about the different units we use every day to measure weight. For example, if you had a bag of biscuits, what unit would you use to measure its weight? Take a moment to jot down your ideas.
✨ Choosing the Right Unit
Now, let's recap. I'm going to ask you about a few things, and I want you to tell me the most appropriate unit to measure them. Think about the length of a snail, the height of your friend, the weight of your math book, and the capacity of your water bottle. Which unit fits best for each?
✨ Converting Units
Next up, conversions! Can you convert 12 kilometers into meters? What about 9 meters and 34 centimeters into just centimeters? Also, convert 1546 grams into kilograms and grams, and finally, 41 liters into milliliters. Remember how these units relate to each other!
✨ Multiplication and Division
Now, let's practice multiplication and division with measurements. I want you to multiply 51 liters 142 milliliters by 3, and also multiply 7 kilometers 342 meters by 2. Then, divide 9 kilograms 78 grams by 3. Make sure you show all of your work clearly, so I can see how you solved the problems.
✨ Word Problem: Total Weight
Finally, let's tackle a word problem. A shopkeeper sold 6 kilograms 150 grams of sugar, 3 kilograms 47 grams of rice, and 2 kilograms of salt. What is the total weight of all the items the shopkeeper sold? Remember to add all the weights carefully. Let's get started and see what you come up with!
