Watch the episode all the way through first.

If you would like to pause at different times to talk with your child about what they notice about how Al and Ada take measurements, watch the longer play version of the video at the link at More Information. It signals pause points and presents prompts and questions. It also suggests activities you may like to explore after watching the episode.

Other ideas to explore

Notice and talk with your child about the different measurements that you and your child use around the home every day (e.g. cooking, the daily temperature, time, driving distances, filling the bath or cup).

After watching the episode, you may like to:

• Talk with your child about informal units of measurement (e.g. hands; feet; toy car), and what you might use to measure different items around the house.
• Measure the heights of different family members, using an informal unit, then measure the heights using an item that has a formal unit of measurement (centimetres).
• Use different family members' hands to measure the length of a table then compare the different number of hand lengths an adult uses compared to a child (talk about why is there a difference in the number of hand lengths counted).

Key words: Length, width, height, small, smaller, long, tall, wide, centimetre.
Key ideas: Counting the total number of units (formal or informal) tells us the measurement of the item. Informal units of measurement, are personal and typically only useful for an individual, but formal units offer consistency, and allow accurate sharing of measurements.
