Numbers & Shapes

Question 1.
Trace the words and numbers. Then draw a lines to the matching set. Answer: Below is the matching set with tracing lines and words, Question 2.
Fill in the missing numbers on the line below. Answer: The given figure consists of numbers from 11 to 17. In between few numbers are missed. So, after filling in the missing numbers the figure is, Question 3.
There were 3 apples on the table. Jan put 6 more apples on the table. How many apples were on the table in all? Show your work.
There were ____ apples on the table in all. Answer: There were 9 apples on the table in all.
Explanation: Given that,
There were 3 apples on the table.
Jan put 6 more apples on the table.
Now, we will find out how many apples were on the table in all.
So, the values are 3, 6
i.e., 6 more means add 6 to 3.
Then the total number of apples is 6 + 3 = 9.
Hence, 6 apples were on the table in all.

Question 4.
CHALLENGE Make a picture that is worth 24⊄. You can use shapes like these. Label your picture. Prove that it is worth 24⊄. Answer: The below picture is labeled as Pent House. The house consists of 2 squares, 2 circles, and 2 triangles.
The total worth of the house is,
2 squares = 2 x 5 = 10
2 circles = 2 x 4 = 8
2 Triangles = 2 x 3 = 6
Therefore, the total worth of the house is 10 + 8 + 6 = 24.

Question 1.
Add. Count the dots to help. Now, we will find out each figure’s additional value.
The following are,
(i) The figure consists of 2 boxes, one box has 4 dots and the other box has 2 dots.
Now, we will find the total number of dots.
So, the values are 4, 2
i.e., 4 + 2 = 6.

(ii) The figure consists of 2 boxes, one box has 3 dots and the other box has 2 dots.
Now, we will find the total number of dots.
So, the values are 3, 2
i.e., 3 + 2 = 5.

(iii) The figure consists of 2 boxes, one box has 6 dots and the other box has 1 dot.
Now, we will find the total number of dots.
So, the values are 6, 1
i.e., 6 + 1 = 7.

(iv) The figure consists of 2 boxes, one box has 3 dots and the other box has 0 dots.
Now, we will find the total number of dots.
So, the values are 3, 0
i.e., 3 + 0 = 3.

(v) The figure consists of 2 boxes, one box has 2 dots and the other box has 2 dots.
Now, we will find the total number of dots.
So, the values are 2, 2
i.e., 2 + 2 = 4.

(vi) The figure consists of 2 boxes, one box has 1 dot and the other box has 4 dots.
Now, we will find the total number of dots.
So, the values are 1, 4
i.e., 1 + 4 = 5.

(vii) The figure consists of 2 boxes, one box has 2 dots and the other box has 5 dots.
Now, we will find the total number of dots.
So, the values are 2, 5
i.e., 2 + 5= 7.

(viii) The figure consists of 2 boxes, one box has 1 dot and the other box has 5 dots.
Now, we will find the total number of dots.
So, the values are 1, 5
i.e., 1 + 5 = 6.

(ix) The figure consists of 2 boxes, one box has 0 dots and the other box has 6 dots.
Now, we will find the total number of dots.
So, the values are 0, 6
i.e., 0 + 6 = 6.

(x) The figure consists of 2 boxes, one box has 3 dots and the other box has 1 dot.
Now, we will find the total number of dots.
So, the values are 3, 1
i.e., 3 + 1 = 4.

(xi) The figure consists of 2 boxes, one box has 6 dots and the other box has 2 dots.
Now, we will find the total number of dots.
So, the values are 6, 2
i.e., 6 + 2 = 8.

Question 2.
Subtract. Cross out the dots to help.  Explanation: Given the problems in a figure,
Each problem consists of one dots box.
Now, we will find the subtraction value of the given value.
The following values are,
(i) 4, 2
i.e., 4-2 The subtracted value is 2.

(ii) 3, 2
i.e., 3-2 After subtraction, the value is 1.

(iii) 6, 1
i.e., 6-1 The subtracted value is 5.

(iv) 3, 0
i.e., 3-0 =3
0 is subtracted from any value, to get the original value only.

(v) 2, 2
i.e., 2-2 The final subtracted value is 0.

(vi) 4, 1
i.e., 4-1 After subtraction, the final value is 3.

(v) 5, 0
i.e., 5 – 0 = 5.
0 is subtracted from any value, to get the original value only.

(vi) 5, 1
i.e., 5 – 1 The subtracted value is 4.

(vii) 6, 0
i.e., 6 – 0 = 6.
0 is subtracted from any value, to get the original value only.

(viii) 3, 1
i.e., 3 – 1 The final value is 2.

(ix) 6, 2
i.e., 6 – 2 The subtracted value is 4.

Question 3.
Marco has 6 dollars. How many more dollars does he need to have 10 dollars in all? Show your work. Marco needs ___ dollars to have 10 dollars in all

Answer: Marco needs 4 dollars to have 10 dollars in all.
Explanation: Given the data,
Marco has 6 dollars.
He needs to have 10 dollars in all.
Now, we will find how many extra he needs.
So, the values are 10, 6
i.e., 10 – 6 = 4. Therefore, Macro needs 4 dollars to have 10 dollars in all.

Question 4.
CHALLENGE Katy has 5 dollars. How many more dimes does she need to have 8 dollars in all? Show your work.
Katy needs ___ more dimes to have 8 dollars in all. Answer: Katy needs 30 more dimes to have 8 dollars in all.
Explanation: Given the data,
Katy has 5 dollars.
Now, we will find out how many more dimes she needs to have 8 dollars in all.
Then, the values are 8, 5
i.e., 8 -3 So, we need 3 more dollars for 8 dollars in all.
But, we will find the dollars in dimes.
we know that 10 dimes = 1 dollar.
i.e., 10 dimes x 3 = 30 dimes.
30 dimes = 3 dollars.
Hence, Katy needs 30 more dimes to have 8 dollars in all.
