Step: 1
We observe from the figure that there is two rows of aeroplanes and each row consists of four aeroplanes.
Step: 2
The number of aeroplanes shown is 2 × 4 = 8.
  [Write the multiplication fact.]
Step: 3
So the multiplication fact shown by the model is 2 × 4 = 8.
Correct Answer is :   2 × 4 = 8
Q5Paula gave 3 slices of watermelon to each one of her friends. If there were three friends, then which number sentence shows the total number of slices she distributed?

C. 3 × 3

Solutions
Share 
Step: 1
Number of slices of watermelon each friend got = 3
  [Paula gave 3 slices of watermelon to each one of her friends.]
Step: 2
Total number of slices of watermelon Paula needs = 3 + 3 + 3
  [There were three friends.]
Step: 3
= 3 × 3
  [Write the addition fact as multiplication fact.]
Correct Answer is :   3 × 3
Q6Choose the number sentence for the array shown.

Q9Edward has 4 groups of balloons. Each group has equal number of balloons. Which number sentence helps to find the total number of balloons that Edward has?


A. 4 × 4 = 16
B. 4 × 2 = 8
C. 4 × 4 = 18
D. 4 × 4 = 14

Solutions
Share 
Step: 1
Number of groups = 4
Step: 2
Each group has 4 balloons.
Step: 3
4 + 4 + 4 + 4 = 16, 4 groups of 4 = 16
Step: 4
4 fours = 16, 4 × 4 = 16
Step: 5
Therefore, the number sentence 4 × 4 = 16 gives the total numbers of balloons that Edward has.
Correct Answer is :   4 × 4 = 16
Q10Choose the appropriate number sentence for the array shown.


A. 4 + 6 = 10

Solutions
Share 
Step: 1
The array shows 4 rows with 6 squares in each row and there are 24 squares in all.
Step: 2
Number of rows × Number of squares in each row = Total number of squares
Step: 3
4 × 6 = 24
  [Substitute the values.]
Step: 4
So, the number sentence that represents the array shown is 4 × 6 = 24.
Correct Answer is :   4 × 6 = 24
