Q1.
Long Jump. Each child can participate in a long jump competition. How far have your friends jumped? Measure as accurately as possible using a combination of ropes. Who jumped the longest distance? Fill the following table.
| Name of the student | Less than 1 m | 1 m | More than 1 m | Actual measurement |
|---|---|---|---|---|
Answer
How to do it:
- Draw a chalk line on the ground. Everyone jumps from this line.
- Mark the place where the jumper's heel lands.
- First guess: is the jump less than 1 m, about 1 m, or more than 1 m? Tick that column.
- Now measure. Lay the 1 m rope from the chalk line. If the jump is longer, add the 1/2 m or the 1/4 m rope to it.
- Write the measurement, and the longest jump wins.
This is the table as it is printed in your book:
| Name of the student | Less than 1 m | 1 m | More than 1 m | Actual measurement |
|---|---|---|---|---|
Sample answer (your class will have its own names and numbers):
| Name of the student | Less than 1 m | 1 m | More than 1 m | Actual measurement |
|---|---|---|---|---|
| Rani | ✔ | 3/4 m | ||
| Bhola | ✔ | 1 m 25 cm | ||
| Mini | ✔ | 1 m | ||
| Jagat | ✔ | 1 m 50 cm |
The longest jump is Jagat's, 1 m 50 cm.
Why it happens: We compare the jumps by putting the numbers side by side.
1 m 50 cm is more than 1 m 25 cm, which is more than 1 m, which is more than 3/4 m.
Tip: Use a combination of ropes. 1 m 25 cm is the
1 m rope and one 1/4 m rope joined end to end.
