Working in 4 Quadrants

The 'Why': An Axis has positive values, but just like a number line, this can pass zero in both directions

This lesson starts with a number line starter to remind students that positive numbers can cross zero and in to negative numbers. This is followed up with a short refresher of what an Axis is and what a co-ordinate is. There is also a short reading and plotting co-ordinates refresher. If you are following the previous lesson, you may find that you don't need to do these activities. If you print these, make sure you delete the answers!

There is then a definition slide about working in 4 quadrants. Link this back to crossing past zero on the number line activity at the start. The follows the same reading and plotting tasks as before appear, except now we are working in 4 quadrants. There is then a task asking students to connect points together to create shapes. As a bonus, they could label what the shapes are.

There are then 6 problem solving tasks. The goal is to get tables to agree with each other. The answers can be written on mini whiteboards. A true of false plenary follows to make sure students understand where the origin is and which quadrant is which.

As extension, there is cartoon dinosaur (borrowed from TES), Battleships and a challenging real life context question about an archaeological dig.
