Lessons 6.1–6.3 Make equal groups.
Complete the table.
| Counters | Number of Equal Groups | Number in Each Group | |
| 1. | 18 | 9 | ________ |
| 2. | 24 | ________ | 8 |
| 3. | 12 | 6 | ________ |
| 4. | 35 | 7 | ________ |
| 5. | 32 | ________ | 4 |
| 6. | 25 | ________ | 5 |
Answer:
| Counters | Number of Equal Groups | Number in Each Group | |
| 1. | 18 | 9 | 2 |
| 2. | 24 | 3 | 8 |
| 3. | 12 | 6 | 2 |
| 4. | 35 | 7 | 5 |
| 5. | 32 | 8 | 4 |
| 6. | 25 | 5 | 5 |
Explanation:
1. Number of counters = 18
Number of equal groups = 9
Number in each group = x
x × 9 = 18
x= 18/9 = 2
Therefore number in each group = 2
2. Number of counters = 24
Number in each group = 8
Number of equal groups = x
x × 8 = 24
x = 24/8 = 3
Thus the number of equal groups = 3
3. Number of counters = 12
Number of equal groups = 6
Number in each group = x
x × 6 = 12
x = 12/6 = 2
So, the number in each group = 2
4. Number of counters = 35
Number of equal groups = 7
Number in each group = x
x × 7 = 35
x = 35/7 = 5
x = 5
Therefore number in each group = 5
5. Number of counters = 32
Number of equal groups = x
Number in each group = 8
x × 8 = 32
x = 32/8 = 4
Thus the number of equal groups = 4
6. Number of counters = 25
Number of equal groups = x
Number in each group = 5
x × 5 = 25
x = 25/5 = 5
So, the number of equal groups = 5
Lesson 6.4
Write a division equation for the picture.
Question 1.
Type below:
__________
Answer: 27 ÷ 3 = 9 or 27 ÷ 9 = 3
Explanation:
Total number of counters = 27
Number of equal groups = 3
Number in each group = 9
The division equation is
Number of counters by number of groups = 27 ÷ 3 = 9
or
Number of counters by number in each group = 27 ÷ 9 = 3
Question 2.
Type below:
__________
Answer: 24 ÷ 4 = 6 or 24 ÷ 6 = 4
Explanation:
Total number of counters = 24
Number of equal groups = 4
Number in each group = 6
The division equation is
Number of counters by number of groups = 24 ÷ 4 = 6
or
Number of counters by number in each group = 24 ÷ 6 = 4
Lesson 6.5
Write a division equation.
Question 3.
Type below:
__________
Answer: 3 groups, 15 ÷ 5 = 3
Explanation:
Step 1:
Starts at 15
Step 2:
Count back by 5s as many times as you can.
Step 3:
Count the number of times you jumped back 5.
You jumped back by 15 three times
There are 3 jumps of 5 in 15.
Question 4.
Type below:
__________
Answer: 24 ÷ 6 = 4
Explanation:
Step 1:
Begins at 24
Step 2:
Subtract with 6 until you get 0.
Step 3:
Count the number of times you subtract with 6.
You subtract 4 times
There are 4 groups of 6 with 24
So, 24 ÷ 6 = 4
