1 video of penguinarium feeding time. Notice and wonder – Withhold info/anticipation discuss data needed to solve some of the wonders
2 How much fish is needed to feed all the penguins?
Eliciting data needed, estimation of these: how many penguins there are in the video, how much does one penguin eat (can google that). Share with neighbours and class.
Reveal 1
In this aquarium, penguins are fed 3 times a day. Breakfast is 5/12 kg of fish, mid afternoon 1 Â¼ kg and supper is â…š kg. See how students solve for how many does one penguin eat. They know equivalent fractions by now, but may use braining camp fraction tools
Reveal 2 – there are 20 penguins. <i style=”backgroundcolor: var(–bbcontentbackgroundcolor); fontfamily: inherit; fontsize: inherit; color: inherit;”>Again see how they solve, may multiply by ten first and the double, may double first and then multiply by ten, may add 2 and Â½ in in groups etc.
