Chapter 08 Grouping and Sharing
Discuss the importance of traffic rules with children.
Let us Do
There are 4 bicycles .
Each bicycle has 2 wheels.
Total wheels = 2 + 2 + 2 + 2 = 8
We are adding 2 for 4 times.
So, 4 times 2 is also 8 or 4 groups of 2 give 8.
You know, times can be written as ‘×’ 4 × 2 = 8.
Number of autorickshaws 🛺 = 2
Each auto has 3 wheels.
Total wheels = 3 + 3 = 6
2 times 3 is 6 or 2 groups of 3 is 6.
2 × 3 = 6
Let us do it for cars.
Number of cars 🚗 = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of wheels in each car = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Total wheels = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{+}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{+}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{=}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
or 3 groups of $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ is $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ times 2 is 6
3 twos are $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \times$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{=}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of octopuses = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of legs in each octopus = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Total number of legs = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{+}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{=}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
2 groups of $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ is $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
2 times $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ is 16
2 eights are $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \times$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{=}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of lines = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of soldiers in each line = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Total number of soldiers = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{+}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{+} $ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{+}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{=}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ times $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ is 40
4 tens are $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ × $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $

How Many?
There are 4 bouquets. | There are 3 bouquets. |
4 groups of 3 flowers | 3 groups of 4 flowers |
$4 \times 3$ | $3 \times 4$ |
Ram used 12 flowers in all. | Gopal used 12 flowers in all. |
___ times 4 is ____ | 6 groups of 4 |
4 groups of 3 flowers | __ times 6 is ____ |
6 × 4 = ______ | 6 × 4 = ______ |
There are ______ flowers. | There are ____ flowers. |
A. There are 8 packets of bindis. Each packet has 5 bindis.
Number of packets = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of bindis in each packet = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ groups of $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ bindis.
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ × $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $= $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ bindis
B. Bharti puts 4 buttons on each shirt. She wants to put buttons on 7 shirts.
Number of shirts = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Number of buttons in each packet = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ groups of $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ buttons
$ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ × $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $= $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ buttons
C. Rita bought 6 pencils of ₹4 each. How much money will she give to the shopkeeper?
Number of pencils = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Cost of 1 pencil = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
Cost of 6 pencils = 4 + 4 + 4 + 4 + 4 + 4 $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \times$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} \text{=}$ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $
So, Rita will give ₹ $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $ to the shopkeeper
Making Multiplication Table
Rudra is making multiplication table of 4 using the table of 2.
