Estimate steps by measuring one average stride (e.g., 0.8 meters) and count approximate strides to the door. For a 12-meter distance, around 15 strides or steps suffice. Quick comparisons refine estimates for accuracy.

a. To estimate steps, measure one stride length—approximately 0.8 meters. Count how many strides cover the distance to the door. For example, if the classroom door is 12 meters away, 12 ÷ 0.8 = 15 strides or steps. Adjust estimates for differing stride lengths. Visualizing distances or comparing with known measurements helps refine guesses.
b. To estimate the school ground’s length, compare its size to a known reference, such as a 100-meter track, or divide it into sections you can approximate. For instance, if the ground appears 100-meter track so, it will take time to go. 100 ÷ 0.8 = 125 steps. Alternatively, length or reference familiar nearby structures, sum them, and validate the estimate distances by your steps.
c. To estimate the distance from your classroom door to the school gate, identify key landmarks along the way, such as the playground or hallway. Break the route into smaller segments, each with an approximate length, and sum them for the total. For example, if classroom door to playground it’s 20 meters and play ground is 100 meters and 20 meter more to the gate. The total distance (20+100+20) is about 140 meters approx. Hence it will take (140 ÷ 0.8 = 175) steps to cover this distance.
d. To estimate the distance from school to home, consider your average travel speed. Walking at 5 km/h, a 15-minute walk covers around 1250 meters. Alternatively, use landmarks or familiar routes to approximate lengths (e.g., “it’s twice the distance to the park, which is 1 km”).Here, the total distance 1250 meters. Hence it will take (1250 ÷ 0.8 = 1562.5) steps to cover this distance.
