Understanding Eureka Math Grade 2 Lesson 3
Eureka Math's Grade 2 Lesson 3, titled "Adding and Subtracting Within 20," introduces students to the concepts of addition and subtraction with numbers up to 20. The lesson aims to help students understand the relationship between addition and subtraction and apply these concepts to real-world problems.
Key Concepts in Eureka Math Grade 2 Lesson 3
- Addition and Subtraction Within 20: Students learn to add and subtract numbers up to 20, focusing on understanding the relationship between addition and subtraction.
- Number Bonds: Students explore number bonds, which help them understand the relationship between addition and subtraction. Number bonds show the different combinations of numbers that make up a given sum.
- Real-World Problems: Students apply their understanding of addition and subtraction to solve real-world problems, fostering a connection between math and everyday life.
Eureka Math Grade 2 Lesson 3 Homework Answers
Now that we've covered the key concepts in Eureka Math Grade 2 Lesson 3, let's dive into the homework answers. Please note that we've provided step-by-step solutions to help your child understand the process rather than just giving away the answers.
Problem 1: Adding Within 20
Problem: Find the sum of 15 and 7.
Solution: To solve this problem, we can use number bonds. We know that 15 is made up of 10 and 5, and 7 is made up of 5 and 2. So, when we add 15 and 7, we are essentially adding 10, 5, 5, and 2 together.
10 + 5 + 5 + 2 = 22
So, the sum of 15 and 7 is 22.
Problem 2: Subtracting Within 20
Problem: Find the difference between 18 and 9.
Solution: To solve this problem, we can use number bonds again. We know that 18 is made up of 10 and 8, and 9 is made up of 10 and -1. So, when we subtract 9 from 18, we are essentially subtracting 10 and 1 from 10 and 8.
10 - 10 - 1 = 8
So, the difference between 18 and 9 is 8.
Problem 3: Solving Real-World Problems
Problem: If a baker uses 12 cups of flour and 5 cups of sugar to make a batch of cookies, how many cups of flour and sugar does the baker use in total?
Solution: To solve this problem, we need to add the number of cups of flour and sugar together.
12 (cups of flour) + 5 (cups of sugar) = 17 cups in total
So, the baker uses 17 cups of flour and sugar in total.
