### Everyday Math Grade 2 Home Link 1.11 Answer Key

**Relations: <, >, =**

**Family Note**

This icon will often appear on the Home Links. This icon tells children where to look in My Reference Book to find more information about the concept or skill addressed in the Home Link. In today’s lesson, we reviewed and practiced using the <, >, and = symbols. For information about relation symbols, see page 75 in My Reference Book.

Show someone at home your My Reference Book. Together find three things you found interesting and write them below.

Question 1.

______________

Answer:

The assignments encourage children to take initiative and

responsibility for completing them.

As they respond with encouragement and assistance,

It will help my child build independence and self-confidence.

Question 2.

______________

Answer:

• Home Links reinforce newly learned skills and concepts.

They provide opportunities for children to think and

practice at their own pace.

• The Home Links will give them a better idea of the

mathematics my child is learning in school.

Question 3.

______________

Answer:

• These assignments are often designed to relate

what is done in school to children’s lives outside school.

This helps tie mathematics to the real world,

which is very important in the in this program.

Explanation:

Found three things interesting and wrote them above.

Explain to someone at home how to do Problems 4–7.

Then write <, >, or = on each blank. Use My Reference Book to look up the symbols.

Question 4.

8 _<__ 12

Answer:

8 < 12,

Explanation:

Given to comapre 8, 12 as 8 is less than 12,

So 8 < 12.

Question 5.

25¢ _>__ 18¢

Answer:

25¢ > 18¢,

Explanation:

Given to compare 25¢, 18¢ as 25¢ is greater than 18¢,

So 25¢ > 18¢.

Question 6.

103 _>__ 53

Answer:

103 > 53,

Explanation:

Given to comapre 103, 53 as 103 is greater than 53,

So 103 > 53.

Question7.

79¢ _=_ 79¢

Answer:

79¢ > 79¢,

Explanation:

Given to compare 79¢, 79¢ as 79¢ is equal to 79¢,

So 79¢ 79¢.

Write numbers in the blanks to make up your own.

Question 8.

___7___ < __9___

Answer:

7 < 9,

Explanation:

Given to find numbers as first number should be

less than second number, So many numbers are there

therefore one set of numbers are 7 < 9.

Question 9. __15____ > __12___

Answer:

15 > 12,

Explanation:

Given to find numbers as first number should be

greater than second number, So many numbers are there

therefore one set of numbers are 15 > 12.

### Everyday Math Grade 2 Home Link 1.12 Answer Key

**Base-10 “Buildings”**

**Family Note**

In today’s lesson, children were introduced to Grade 2 Explorations. Explorations are small-group, hands-on activities designed to introduce or extend mathematical topics. One of the Explorations reviewed the values represented by base-10 blocks. Children made “buildings” with the blocks and calculated the values of the buildings.

Please return this Home Link to school tomorrow.

Look at the picture of a “building” that is made with base-10 blocks.

Count the value of the flats, longs, and cubes that make up the building. What number does the building show? Use the symbols in the box to help you. _158__

Write about how you counted the blocks.

Answer:

158 number does the building show,

Explanation:

Counting the value of the flats, longs, and cubes

that make up the building as shown above are

flats – 1 – 1 X 100 blocks = 100 blocks, as 1 flat has 100 blocks,

longs – 5 – 5 X 10 blocks = 50 blocks, as 1 long has 10 blocks,

cubes – 8 – 8 X 1 block = 8 blocks,

therefore in total the building showm100 + 50 + 8 = 158 number.
