Quarantine School – Resource Packs
Engaging, exciting, thought-provoking learning triggers!
Beginning Wednesday, 1st April, 2020
CHECK IT OUT!

The learners are bored, the teachers are unavailable, and the parents are tired.

Chachi is here to help!

We are on day 13 of the Quarantine School series and ready with the latest resource pack. This time we do a little bit of maths and learn about growing plants! These learning triggers should ideally be used by parents or teachers as conversation starters with learners. Based on the learner’s interest or your intended learning objective, you can pick whichever trigger you like and facilitate a journey of exploration!

  1. How rich is a billionaire?
  2. How do red chillies grow?
  3. What’s bigger – one large pizza or two small pizzas?

How rich is a billionaire #

Starting at 1, what’s the biggest number that you can count to in one breath? Do you want to give it a try? Can you count to a hundred?

  • Let’s say you can count to 20 in one breath. How many breaths will you need to count to 100?

Now let’s look at this situation in a slightly different manner.

  • Imagine it takes you one second to count one number. How long will it take you now to count to 1000? Can you convert this is into minutes and seconds? I am sure you remember that one minute has 60 seconds.

Now the big question – how much time will it take you to count to a billion?

  1. Let’s deal with something smaller first - let’s take one million, that is 1,000,000. Can you find out how much time it will take you to count to one million if you counted one number per second? Let’s make it a little easier for you by calculating in days instead of seconds. How many seconds does a day have? Simply multiply the number of hours with number of minutes and number of seconds, i.e, 24 x 60 x 60. Use a calculator if you like!
  2. Finally, let’s come to a billion, which is 1,000,000,000. Do you see how much larger one billion is than a million? A thousand times!
  3. Can you find out how much time it will take you to count to a billion? To make it easier again, let’s count in years instead of days. How many seconds does a year have? To get a rough estimate simply multiply the number of seconds in a single day from the previous step and multiply it by 365!

How different are the answers? As a hint, counting to a million would take a few days but counting to a billion would take many years! Find out the exact numbers!

Now imagine how much richer a billionaire is from a millionaire!


How do red chillies grow? #

Do you like spicy food? You probably know that red chillies are a common ingredient in spicy food. But how do you grow red chillies?

First, we have to find out how any fruit or vegetable is grown! Let’s outline the steps we need to follow. Ask an adult or search on the internet for answers.

  1. What all ingredients do you think you would need to grow a plant? Make a list!
  2. Now that all the ingredients are ready, how do you use them? Find out the process behind planting. When do you put the seeds in? Do you have to prepare the soil first? Do you need any fertilisers?
  3. With that we can grow our plant! Yay! But where do you find seeds for red chillies? Try looking inside some chillies.

Let’s do a little experiment. Prepare two pots. In one pot, plant seeds from a red chilly. In the other, plant seeds from a green chilly. Which one do you think will grow first? Will there be a difference in the two plants? Try it and find out!


What’s bigger – one large pizza or two small pizzas? #

Imagine you go to a pizza place with ₹500. One small pizza costs ₹250 and one large pizza costs ₹500. Should you buy two small pizzas or one large pizza to get the better deal? Let’s find out!

Let’s assume that the diameter of the small pizza is 10 inches and that of the large pizza is 12 inches.

  1. Since the pizza is circular in shape, we can simply calculate the area of the circle to find out how much pizza we get. We will ignore the thickness of the pizza because it is likely that all pizzas have the same thickness. First though, can you write down the radius of the small and large pizzas?
  2. Now, what is the area of a circle? Find the formula in your maths textbook or search for it online. Make sure your formula uses radius and not diameter!
  3. Let’s calculate the area of one large pizza then! Done? Now what’s the area of one small pizza? Multiply this by two because we can buy two pizzas in ₹500. Is the area of two small pizzas larger or smaller than that of one large pizza?

What does that tell us? Should you buy two small pizzas now or one large one?

What if there was also an extra-large pizza with a diameter of 14 inches? Will two small pizzas still give you a better deal? Find out with the above method!
