## Texas Go Math Grade 5 Module 4 Assessment Answer Key

**Concepts and Skills**

Question 1.

Explain how the position of the decimal point changes in a quotient as you divide a number by 10,100, and 1,000. (TEKS 5.3.G)

Answer:

Move the decimal point to the left for as many places (steps) as there are zeros in the factor 10, 100, or 1000.

Explanation:

28 Ă· 10=2.8Â — Move the decimal point one step to the left.

28Ă· 100 = 0.28 –Move the decimal point two steps to the left. You need to write zeros in front of the number.

28 Ă· 1000 = 0.028 — Move the decimal point three steps to the left. You need to write zeros in frontÂ of the number.

**5th Grade Module 4 Assessment Answer Key Go Math Question 2.**

Explain how you can use base-ten blocks to find 2.16 Ă· 3. (TEKS 5.3.F)

Answer:

Explanation:

**Step 1:**

Use base-ten blocks to show 2.16.

Remember that a flat represents one, a tong represents one tenth and a small cube represent one hundredth.

Therefore, 2 ones, 1 tenths, and 6 hundredths.

**Step 2**

Share the ones.

Share the ones equally 3 groups.

There will be 0 one share in each group and 2 ones Left over _

( Notice that 2 ones cannot be shared among 3 groups without regrouping.

Therefore, you have to regroup the ones by rep(acing them with tenths)

**step 3**

Share the tenths.

(Remember that 2 ones (left over and the one is equal’ to 10 tenths.)

So, now We have 21 tenths in total.

And there will be 7 tenths share in each group, 21Ă· 3

**Step 4:**

Share the hundredths.

Share the 6 hundredths equally among the 3 groups.

There will be 2 hundredths share in each group, 6 Ă·3

**step 5**

Therefore,

2.16 Ă·3 = 0.72

**Complete the pattern. (TEKS 5.3.G)**

Question 7.

6.1 Ă· 8

Answer: 0.7625

Explanation:

8 goes into 61, 7 times with remainder of 5

8 goes into 50, 6 times with remainder of 2

8 goes into 20, 2 times with remainder of 4

8 goes into 20, 5 times with no remainder 0

So Answer is 0.7625

**Go Math Grade 5 Module 4 Answer Key Question 8.**

492.6 Ă· 48

Answer: 10.2625

Explanation:

48 goes into 492, 10 times with remainder of 12

48 goes into 126, 2 times with remainder of 30

48 goes into 300, 6 times with remainder of 12

48 goes into 120, 2 times with no remainder 24

48 goes into 240, 5 times with no remainder 0

So Answer is 10.2625

**Use models or strategies to divide. (TEKS 5.3.F, 5.3.G)**

Question 9.

Answer: 0.87

Explanation:

STEP 1**
**Use base-ten blocks to show 4.35.

Remember that a flat represents one. A long represents

One tenth, and a small cube represents one hundredth.

There are 4 one(S), 3 tenth(s), and 5 hundredth(s).

STEP 2 Share the ones.

4 one(S) cannot be shared among 5 groups without regrouping. Regroup the one(s) by replacing them with tenths.

There is 0 one(s) shared in each group and 4 one(s) left over.

There are now 43 tenth(s). And 8 tenth(s) shared in each group and 3 tenth(s).left over.

STEP 3 share the tenths.

Two tenths cannot be shared among 3 groups without regrouping. Regroup the tenths by replacing them with hundredths.

There are 0 tenth(s) shared in each group and 3 tenth(s) left over.

STEP 4 Share the hundredths.

Share the hundredths equally among the 5 groups.

There are Â 35 hundredth(s) and 7 hundredth(s) shared in each group and 0 hundredth(s) left ove

Remember that a flat represents one. A long represents

One tenth, and a small cube represents one hundredth.

There are 6 one(S), 2 tenth(s), and 4 hundredth(s).

STEP 2 Share the ones.

Share an equal number of ones among 3 groups.

There is 2 one(s) shared in each group and 0 one(s) left over.
