Number (addition and subtraction): Hungry Hummingbird
Challenge level ⭐⭐
(designed for children with prior knowledge of the Year 3 and Year 4 programme of study)
We are learning how to solve a natural world problem by using and applying our knowledge and skills of number and addition.
Useful prior knowledge:
- To read and write 4 and 5-digit numbers
- To add and subtract large numbers using efficient mental methods
Hummingbirds are known for their aerobatic skills. They can hover, fly backwards, sideways and even upside down! Just like a bee, a hummingbird is an important pollinator. As it drinks nectar from deep inside a flower, it transfers pollen from its beak and neck to the flower. This can lead to the creation of a new seed and, ultimately, a new plant.
In this fascinating clip, a bee hummingbird (the smallest bird in the world) can be seen feeding on nectar – a sugar-rich liquid. How do think the size of this tiny bird compares to an insect? Watch the clip to find out.
