Add Our Points Class 2 NCERT Solutions & Concepts

Welcome to 'Add Our Points', an exciting chapter where we learn how to add numbers while playing games! In CBSE Class 2 Maths Chapter 10, we will learn how to quickly count points and add them up to find out who wins a game. Whether you are tossing a ball, skipping a rope, or throwing dice, addition helps us keep score. We will explore how to add multiple numbers together, use 10s to make adding easier, and practice skip-counting on a number line. By the end of this guide, you will master adding single-digit and double-digit numbers, which is a key skill for everyday life. Let's join YoLearn AI Tutor on this fun mathematical adventure and score some big points!

Understanding "Add Our Points"

In this chapter, we look at fun games where we need to add points to see who won. Imagine you are playing a game with your friends. In the first round, you score 6 points, and in the second round, you score 8 points. How do you find your total score? We add them together! We can write this as $6 + 8$. To add these numbers quickly, we can count forward from the bigger number. Start at 8 and count 6 steps forward: 9, 10, 11, 12, 13, 14. So, your total score is 14 points!

Learning to group numbers into tens also makes adding much faster. For example, to add $7 + 5$, you can think of it as $7 + 3 + 2$, which is $10 + 2 = 12$. This clever trick helps us add faster in our heads.

How to Add Three Numbers Easily

  1. Step 1: Write down the numbers — Write the three numbers in a line. For example, let's add 5, 3, and 5.
  2. Step 2: Look for 'Friends of 10' or Doubles — Look at the numbers to see if any two of them add up to 10 or make a matching pair. In our example, we have two 5s. We know that 5 + 5 makes exactly 10!
  3. Step 3: Add the last number to 10 — Now, take that 10 and add the remaining number, which is 3. So, 10 + 3 = 13.
  4. Step 4: Write the final answer — Our final sum of 5 + 3 + 5 is 13. This method makes big additions super easy!

Quick Tips for Super-Fast Addition

  • Look for Friends of 10: Numbers like 1 and 9, 2 and 8, 3 and 7, 4 and 6, or 5 and 5 add up to make exactly 10. Find them first!
  • Start with the Bigger Number: When adding two numbers, start counting from the larger number to save time and prevent mistakes.
  • Use Your Fingers or a Number Line: If you get stuck, jump forward on a check board or use your fingers to count step-by-step.
  • Double Trouble: Learn double additions like 2+2=4, 3+3=6, 4+4=8, and 5+5=10 to add matching groups instantly.

Practice Questions with Solutions

  • Q: Sameer threw a die twice. He got 6 on his first turn and 5 on his second turn. How many points did he get in total? A: Step 1: Write down the points from each turn. First turn points = 6. Second turn points = 5. Step 2: Add the two numbers together: 6 + 5. Step 3: Start from 6 and count forward 5 steps on your fingers: 7, 8, 9, 10, 11. Final answer: Sameer got 11 points in total.
  • Q: In a forest game, a bunny hopped 7 times in the first round, 4 times in the second round, and 3 times in the third round. Find the bunny's total hops. A: Step 1: Write down the hops for all three rounds: 7, 4, and 3. Step 2: Look for 'Friends of 10'. We know that 7 and 3 make 10. So, add 7 + 3 first to get 10. Step 3: Now, add the remaining number 4 to 10: 10 + 4 = 14. Final answer: The bunny took 14 hops in total.
  • Q: Reema has 8 red beads and 9 blue beads. How many beads does she have in total? Let's use the 'make a 10' method. A: Step 1: Write down the number of beads: 8 red beads and 9 blue beads. Step 2: To make a 10 from 9, we need 1 more. We can take 1 bead from the 8 red beads. This leaves us with 7 red beads. Step 3: Now add the group of 10 and the remaining 7: 10 + 7 = 17. Final answer: Reema has 17 beads in total.
  • Q: Anish scored 12 points in a ring-toss game and his sister scored 15 points. Who scored more points and by how much? A: Step 1: Compare the two scores. 15 is greater than 12, so Anish's sister scored more points. Step 2: To find by how much, subtract Anish's score from his sister's score: 15 - 12. Step 3: Count forward from 12 to 15: 13, 14, 15. The difference is 3. Final answer: Anish's sister scored more points by 3 points.

Frequently Asked Questions

How does 'making a 10' help us add faster?

Making a 10 is a mental math strategy where we pair numbers that add up to 10, like 7 and 3. Once we have 10, it is much easier to add the remaining numbers to get the final sum quickly.

What is the easiest way to add three numbers together?

To add three numbers, first look for any two numbers that add up to 10 or make a double. Add those two first, and then add the third number to that result for a fast and easy answer.

Can we count backward to add points?

No, to add points we must always count forward or jump ahead. Counting backward is used for subtraction when we lose points or take things away.
