A Visit to an Amusement Park

A group of children visited an amusement park.

$ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} None of us can sit on the horse swing altogether.

There are 3 bogies. 3 + 3 + 3 = 9 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Total energy $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ children can sit in 3 carriages.

$ \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{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ = 0 $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $

Total energy $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ children can sit in the swing.

After riding on the swings, children planned to eat jalebis. Each plate of jalebi has 3 pieces. They ordered 6 plates of jalebi. jalebis

$ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

6 times 3 is $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Discuss the number of groups in each activity through questions like how many children are there in the picture, how many children are there are sitting in each compartment, total number of children on board the ride.

Travelling in the Bus

2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

9 times 2 = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Total number of people in the bus = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Some crates of water bottles are kept in the bus. Count them. them.

$ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

4 times 5 = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Total number of bottles on the bus = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Cheenu bought some packs of erasers, pencils, and apples from the shop. Find the total of each item.

A.

2 + 2 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

4 times 2 = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Total number of erasers = 0 $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $

B.

3 + 4 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ pencils

5 times 3 = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

Total number of pencils = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $

C.

3 + 4 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ + $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ = $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $ apples

3 times 3 = $ \begin{array}{|l|} \hline \hspace{6 mm} \\ \hline \end{array} $

Total number of apples = 0 $ \begin{array}{|l|} \hline \hspace{6mm} \ \hline \end{array} $
