What to do with this activity?

You may never have heard of geocaching, which is a really great excuse for an outdoor adventure with your child. It's a bit like Pokémon Go, but it's been around longer (since the year 2000) and is more respectful of the environment and nature. It can make a great shared hobby. It's important to always accompany your child in this adventure. 

Geocaching is a kind of treasure hunt - cache is a French word that means hidden treasure - that has spread to nearly every country in the world. One person hides a weather proof box which contains a log book and other small items (the treasure) that can be swopped. They then put the details of the geocache and its satellite location online so that other people can find it. Geocaches get hidden in amazing places, so it's challenging and satisfying to find one. Watch this video for a quick introduction to geocaching. 

Ideally you need a GPS device. GPS stands for Global Positioning System. It works out an exact location, by using satellites that orbit the earth. The location is expressed as a number that tells you how far east/west and north/south you are (latitude and longtitude). If you don't have access to a GPS receiver, you can go geocaching using a free app on your smartphone. Download one for android phones here, or for an iphone here. However, this won't be as safe or accurate as a GPS in finding geocaches in more remote areas. Read this for more tips about geocaching with kids, and here are Geocaching Ireland's guidelines







  • Why am I doing this?

    Maths makes sense to children when they use it in everyday life - like measuring things, working out distances, estimating food for dinner or money for groceries. The more opportunities you give your child to use the maths they learn at school through everyday activities the more they will understand and enjoy working with numbers.

  • How can I do more?

    Discuss maths that you see around you. For example, talk about sales in shops – half price, 25% off, what is good value? Or how much will the item cost after the discount?
