Answer Key for Lesson 7 Homework 5.2
If you are looking for the Answer Key for Lesson 7 Homework 5.2, you are able to find it on a Youtube channel named The Homework Helper. In this channel, there is a video entitled Engage NY // Eureka Math Grade 5 Module 2 Lesson 7 Homework. The video was uploaded on September 20th, 2019 and it has been watched more than 24k times. The length of the video is 27 minutes 19 seconds.
Here are the questions of the Lesson 7 Homework 5.2.
1. For the number 1, you are required to draw an area model and then you have to solve using the standard algorithm. You need to use arrows to be able to match the partial products from your area model to the partial products in your algorithm.
a. 273 x 346
b. 273 x 306
c. In those parts a and b have three-digit multipliers and then you are asked the reason for their three partial products in Part a and only two partial products in part b.
2. In the number 2, you are asked to solve the questions by drawing the area model and using the standard algorithm.
a. 7,481 x 290
b. 7,018 x 209
3. In the number 3, you are required to solve the questions by using the standard algorithm.
a. 426 x 357
b. 1,426 x 357
c. 426 x 307
d. 1,426 x 307
4. In the number 4, there is a story where the Hudson Valley Renegades Stadium holds a maximum of 4,505 people and during the height of their popularity, they were able to sell out 219 consecutive games. The question is about the amount of tickets which were sold during this time.
5. In the number 5, there is a story where one Saturday at the farmer’s market, each of the 94 vendors made $502 in profit and then the question is about the profit that all vendors made that Saturday.
Here are the answers to those questions according to the video of The Homework Helper entitled Engage NY // Eureka Math Grade 5 Module 2 Lesson 7 Homework.
1. a. 94,458
2. a. 2,169,490
3. a. 152,082
If you want to know how to do the questions or the way to answer these questions so that you can get these answers, you are able to watch the video on Youtube until the end. So, you will get the answer clearly.
What’s in Lesson 7 5.2 in NYS Common Core Mathematics Curriculum?
In the lesson 7 5.2 in NYS Common Core Mathematics Curriculum, the goal of the lesson is to make students be able to connect area models and the distributive property to partial products of the standard algorithm with renaming.
In the list below, you are able to see the suggested lesson structure.
- Fluency Practice will be in 12 minutes.
- Application Problem will be in 6 minutes.
- Concept Development will be in 32 minutes.
- Student Debrief will be in 10 minutes.
So, the total time is 60 minutes.
In the Fluency Practice, there will be a sprint to multiply by multiples of 10 and 100 in 8 minutes. There is also multiplying using the area model in 4 minutes. In the sprint, it is the review fluency activity which can help preserve skills students learned and mastered in Module 1 and lay the groundwork for multiplying with three-digit factors in the lesson of today.
In multiplying using the area model, it is important for you to note that the area model will be utilized again in this lesson. It means that a short review will bolster the solidity of the previous learning before adding on the complexity of factors with more digits.
In the application problem, there is a story where the length of a school bus is 12.6 meters. Let’s say that 9 school buses park end to end with 2 meters between each one. Then, you need to calculate the total length from the front of the first bus to the end of the last bus. Well, this is a problem which is created to bridge to the current lesson with multi-digit multiplication while also reaching back to decimal multiplication work from module 1. Students will have to be encouraged to estimate for a reasonable product prior to multiplying. Students must be encouraged to use the most efficient method to be able to solve this problem.
When multiplying numbers which are multi-digit, particularly those with three-digit multipliers, students must be encouraged to remember which partial product that they are discovering. With it, students will be helped to remind the zeros in the partial products.
In the Problem Set which is alloted 10 minutes, students need to do their personal best so that it can be completed. For several classes, it may be suitable to modify the tasks by specifying which problems that they work on first.
What about Student Debrief? It is aimed to invite reflection and active processing of the total lesson experience. Students must be suggested to review their solutions for the Problem Set and they need to check work and it can be done by comparing answers with a partner before going over answers as a class. Teachers need to guide students in a conversation to debrief the Problem Set and process the lesson.
After the Student Debrief, students must be instructed to complete the Exit Ticket. Reviewing their work will help to assess the students’ understanding of the concepts which are presented in this lesson so that you can plan more effectively for future lessons.
