📏 Part 1: Estimating and Measuring

WALT (We Are Learning To): Measure different lengths using non-standard units such as body parts.

Instructions: Choose 5 objects around your classroom. First estimate, then measure using your hand span, foot length, or arm length. Record your results in the table below.

Object	My Estimate	Body Part Used	Actual Measurement
Example: My desk	3 hand spans	Hand span	4 hand spans
1. _________________	_______________	_______________	_______________
2. _________________	_______________	_______________	_______________
3. _________________	_______________	_______________	_______________
4. _________________	_______________	_______________	_______________
5. _________________	_______________	_______________	_______________

Hand span - because _________________________________ Foot length - because _______________________________ Arm length - because ________________________________

🔢 Part 2: Extension - Converting to Metric Units

Challenge: Use a ruler to measure your body parts in centimetres, then convert your measurements!

My hand span = _______ cm

My foot length = _______ cm

My arm length = _______ cm

Object: ________________________

Body part measurement: _______ × _______ cm = _______ cm

(number of body parts) × (length of body part) = (total length)

Hand spans Metres Foot lengths
