In today’s lesson, “Welcome to Fun Learning with Frogs,” students engaged with a story about frogs to practice their reading and math skills. They learned to solve a puzzle by subtracting the number of frogs that left the grass and confirming their answers through addition, ultimately discovering that 8 frogs remained while 7 had left. The lesson emphasized the enjoyment of learning through storytelling and encouraged continued practice in math.
  1. How many frogs were there at the beginning of the story?
  2. What did we do to find out how many frogs were left in the grass?
  3. Can you tell me how many frogs left the grass in total?

Welcome to Fun Learning with Frogs!

Hello, friends! Today, we’re going to have some fun with a story about frogs. We’ll be using our reading and math skills to solve some puzzles. Are you ready? Let’s jump in!

Our Frog Story

Once upon a time, there were 15 frogs happily sitting in the grass. But then, something happened! Five frogs decided to jump into the water, and two frogs hopped away to explore.

Solving the Frog Puzzle

Let’s read the story again to figure out what happened to the frogs. We started with 15 frogs in the grass. Then, 5 frogs jumped into the water. If they jumped away, we need to subtract them from the total. So, we have:

15 – 5 = 10 frogs left in the grass.

Next, 2 more frogs hopped away. Let’s subtract those too:

10 – 2 = 8 frogs still in the grass.

Counting Frogs That Left

Now, let’s find out how many frogs left the grass in total. We know 5 frogs jumped into the water and 2 frogs hopped away. Let’s add those numbers together:

5 + 2 = 7 frogs left the grass.

Checking Our Answers

We found that 8 frogs stayed in the grass. Let’s check if we can find another way to solve this. We can think of the frogs that left as one big group:

15 – 7 = 8 frogs still in the grass.

Both ways give us the same answer, so we know we’re correct!

Great Job!

Wow, you did an amazing job solving the frog puzzle! Remember, math can be fun when we use stories and our imagination. Keep practicing, and you’ll get even better. See you next time for more fun learning adventures!

Don’t forget to check out more fun videos and activities. See you soon!

  • What do you think the frogs might be doing in the water or while exploring? Can you imagine a little story about their adventures?
  • Have you ever seen a frog in real life? Where was it, and what was it doing? Share your experience with the group.
  • If you were a frog, would you prefer to stay in the grass, jump into the water, or explore somewhere new? Why?
  1. Frog Jump Game: Gather some small toys or objects to represent the frogs. Start with 15 objects and act out the story. Have 5 “frogs” jump into a bowl of water and 2 “frogs” hop away to another spot. Count how many are left. Try different numbers and see how the total changes. This will help you understand subtraction in a fun way!

  2. Frog Drawing Challenge: Draw a picture of the 15 frogs sitting in the grass. Then, draw 5 frogs jumping into the water and 2 frogs hopping away. Count how many frogs are left in your drawing. Share your drawing with a friend or family member and explain what happened to the frogs.

  3. Frog Story Time: Create your own story about frogs using different numbers. How many frogs start in your story? How many jump into the water or hop away? Write down your story and solve the math puzzle you created. Share your story with your class or family and see if they can solve it too!

Sure! Here’s a sanitized version of the YouTube transcript:

What we have is a new worksheet that combines two of my favorite things: reading and math. These are called word problems, and we’ve got some tricky word problems for us today. But I know that you can do it because you are so smart! So let’s get started.

We’ve got tricky word problems, part one. It says to read the number story and answer the questions. What we’re going to do is read the number story two times. The first time, we’re going to read it to understand what the story is about, and then the second time, we’re going to read it to figure out what to do with the numbers in the story.

Okay, are you ready? Here we go!

There were 15 frogs in the grass. So it’s a story about frogs. Five frogs jumped into the water, and two frogs hopped away.

Okay, that was the first time. Now we’re going to read it again and figure out what to do with the numbers. I’m going to make notes to myself so that I can figure out what to do with the numbers in this story.

So let’s read it again: There were 15 frogs in the grass. So what I’m going to do is make a note to myself: there are 15 frogs, and they start off in the grass.

So here’s 15. There are 15 frogs in the grass. Then it says five frogs jumped into the water. So we’ve got the number 15, and then five of them go away. If they go away, we would subtract, right? So five of them jumped into the water.

Then it says two frogs hopped away. So then two of them go away.

Alright, so then it says, “How many frogs left the grass in total?” Now, the first time I read this, I thought it said “left in the grass” because my brain was trying to figure out what the whole problem meant. But don’t be tricked by that! It says, “How many frogs left the grass in total?”

So if they left, they were the ones that went away. So we’ve got five that went away and two that went away from the grass. So what we need to do here is add up those two numbers.

So we’ve got five and two. How many does that equal? Now, over here, I put subtract because that means they went away from the 15 total. But the question says, “How many frogs left the grass in total?” The words “in total” let us know that we need to add them up.

So five plus two equals seven. Let’s find that equation over to the side: five plus two is seven.

Let’s see if we can find it. Five plus two is eight? Nope, that’s not the right answer. Five minus two? Nope, we’re trying to add in total. That wouldn’t be right. And then two plus five equals seven. Five plus two and two plus five are the same thing, so that’s actually the correct answer.

So I’m going to put a check right here next to that equation.

Okay, then the next one says, “How many frogs stayed in the grass?” Check for correct solutions. There are going to be two answers to this one.

Okay, so let’s figure out what we need to do. We’ve got 15 minus 5 minus 2. That was originally going to give us the answer: 15 minus 5 minus 2.

Well, there it is: 15 minus 5 minus 2 equals 8. I think that that’s correct, but let’s go ahead and solve this problem so that we can figure out how much this is.

So let’s take 15 and count down: 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5. And we’re going to do just that. We’re going to take away five. So one, two, three, four, five. And we’re also going to take away two: one, two.

And that is going to give us the answer. Hopefully, that’s eight. So let’s figure it out: one, two, three, four, five, six, seven, eight. That’s correct! So 15 minus five minus two equals eight.

So I’m going to put a check next to that one. But the directions said to check for two correct solutions.

So let’s see if we can find another solution. Now remember back to this first problem where we had two plus five equals seven. Seven can be written instead of five and two.

So let’s see if we can find a problem that says 15 minus seven, which is the same as five and two equals. And we know that the answer is going to be eight total because it’s the same thing whether we count five or seven.

So 15 minus seven, let’s see if we can find that one: 15 minus seven equals eight. There it is! That’s our second solution to this problem.

That was really tricky today, but you all did a great job! I will see you again next time. Bye!
