After 2 minutes, Ollie had eaten** 8 ticks**. After 3 minutes Ollie had eaten** 20 ticks**, and after 4 minutes Ollie had eaten **38 ticks**.

**Can you suggest the number of ticks that Ollie ate in 10 minutes? **

**Compare and explain how you arrived at your number to a classmate.**

**Did you know?**

Oxpeckers line their nests with hair that they have plucked from their animal host. Hosts can include giraffes, zebras, wildebeest, rhinos and buffalos.
