4 Measuring Length (Handspan & Fingers) (Pages 76-78)

✋ Concept: Handspan vs. Fingers

A handspan is the distance from the tip of the thumb to the tip of the little finger when the hand is fully stretched. We use handspans for larger objects (like a table) and fingers (width of fingers together) for smaller objects (like an eraser).

Page 77: Think and Answer (Example Answers)

(Note: Answers will vary based on the child's hand size and the object. Here are example estimates).

A. My table is 8 handspans long.
B. My bag is 3 handspans long.
C. My classroom blackboard is 20 handspans long.
D. My Maths book is 2 handspans long.
E. My arm is 4 handspans long.

5 Measuring with Footspan & Heavy/Light (Pages 79-80)

Page 79: Measure by Footspan (Example Estimates)

A footspan is the length of your foot from heel to toe. Children will have different answers.

Distance to door: ~12 footspans.
One side of classroom: ~25 footspans.
Bed to washroom: ~15 footspans.

Page 79-80: Tick the heavier/lighter object.

A. Tick the Heavier Object

i. Salt vs Rice Bag ➔ Tick Rice Bag
ii. Backpack vs Small Box ➔ Tick Backpack

B. Tick the Lighter Object

i. Bucket vs Mug ➔ Tick Mug
ii. Big Box vs Small Pencil Box ➔ Tick Small Box

6 Capacity - Holding Water (Pages 81-82)

💧 Concept: Capacity

Bigger containers (like a bucket or a big jug) can hold more water than smaller containers (like a mug or a glass).

Page 81: C. Circle the one which holds more water.

i. Bucket vs. Mug ➔ Circle the Bucket.

ii. Big Matka (Pot) vs. Small Pot ➔ Circle the Big Matka.

iii. Teapot vs. Small Cup ➔ Circle the Teapot.

Page 82: D. Tick the amount of water you need for the given activities.

i. For brushing the teeth: Tick A mug full of water. (We don't need a whole bucket just to brush!)

ii. For bathing: Tick A bucket full of water.

iii. For preparing 2 glasses of lemon water: Tick A jug of water. (A jug holds a few glasses. A bucket is too much).

iv. For watering a plant: Tick A mug of water. (Unless it's a very big tree, a mug or watering can is enough).

Extra Practice Questions

Q1. Which is heavier: A completely filled water bottle or an empty water bottle?

Answer: A completely filled water bottle is heavier because water adds weight to the bottle.

Q2. To measure the length of your eraser, what will you use: Handspan or Fingers?

Answer: We will use Fingers because an eraser is a very small object.

Q3. Why is it better to use a bucket and mug for bathing instead of a running shower?

Answer: It is better because it helps in saving water. A shower wastes a lot of water as it continuously runs.
