Recently we learnt about location. We learnt how to use grid references, co-ordinates, compass points and also compared different types of maps.
We began by making and using a giant classroom grid reference system. We drew our classroom using correct grid references to locate objects.
Aside from grid references, such as B3, we discovered that there are other ways to describe the location of particular objects. The Cartesian co-ordinate system was named after a man called Rene Descartes who was also known as Cartesius. Unlike grid references, the Cartesian system only uses numbers.
There are four quadrants in the Cartesian co-ordinate system, each with co-ordinates created using the x and y axis. It’s important to remember to read the x co-ordinate first. Campbell shared his strategy for remembering this, which is Jack goes across the beanstalk and then up or down. Kaitlyn shared her strategy, which is x comes before y in the alphabet.
The image below is from Maths Worksheets for Kids and names the different quadrants.
We completed some activities like the one below from the Maths Aid website to practise finding certain points.
We used quite a few websites to learn about grid references and co-ordinates. You might like to complete the activities too!
Task 1. Click HERE to help Billy Bug find his food.
Task 2: Click HERE to help find the dinosaur bones.
Task 3. Click HERE to answer questions about co-ordinates in the Cartesian co-ordinate system.
Task 4. Click HERE to answer more questions about the Cartesian co-ordinate system.
We also compared satellite/aerial views with other maps. There are lots of differences between the two maps below. Both of them show our school. Most of us prefer the satellite view as it is easier to see details and it gives a clearer picture of what the actual area looks like.
Which map do you prefer? Why?
When do you use mapping skills?
