Take feedback and discuss the children's use of vocabulary, using the video as a prompt.
Display the Presentation: Ocean young. Ask the children to think about where ocean animals come from.

Make presentation full-screen
Encourage them to write questions about the ocean young and their life cycles using the keywords as prompts.
Take feedback, prompting them to recall where they should place capital letters and question marks.
Possible questions include:
- Which animal does that offspring belong to?
- Do dolphins give birth to live young?
- Do fish lay eggs?
- What stage of the life cycle is that?
Click on the images to reveal further information about each creature shown, if required.
Arrange the children into groups of three. Hand out the Activity: Sorting life cycles (pre-cut, one between three) and whiteboard pens for them to write on the desks. Alternatively, provide whiteboards for them to position the pictures and write labels on.
Ask the children to group their cards by animal. Encourage them to organise the pictures into piles and add suitable labels.
Display slide 1 of the Presentation: Life cycles of ocean animals, which matches the Activity: Sorting life cycles.
