Learning Intention: We are learning to explore the use of coordinates to plot points and describe positions and movements on a grid (MTH 2-18a)
Success Criteria:
I can use coordinates to locate a point on a grid
I can use coordinates to describe and locate a unique point on a grid
I can plot coordinates on a grid
Primary 5 have been learning all about coordinates in maths. We know that you use coordinates to locate a specific point, usually on a map. We have been learning how to read coordinates accurately by finding the number that appears on the horizontal, or x axis first, then reading the number on the vertical, or y axis. Last week we looked at how to find and read coordinates in a grid with 1 quartile, but this week we challenged ourselves by locating and reading coordinates on a grid with 4 quartiles! That meant we had to use our knowledge of negative numbers to help us.
We rotated round three stations to demonstrate our knowledge and understanding:
- Teaching group- we plotted coordinates on a grid to create a pictures of an alien creature
- Game group- some of played a game of Spinning Coordinates, and others played Coordinates Bingo
- ICT group- Sumdog Challenge
We also used the AAL network to use our own and the school’s devices to try and and find the coordinates of our houses, learning about the meaning of latitude and longitude.
Coordinates are so powerful and used loads as you move on with your learning in maths. Try plotting these set of coordinates
(0,0) (1,2) (2,4) (3,6) (4,8) (5,10)
join them up in order- what do you get?
Can you see the connection between the x coordinate and the y coordinate….. mmmm
We made a diagonal line with the coordinates we were given and we noticed that the x coordinate links with the y coordinate because the x coordinate is double the y coordinate.
Me and my partner made a diagonal line with the coordinates and we noticed that the x coordinate links with the y coordinate because the x coordinate is doubled to the y coordinate.
I worked with Kiera and we found out that the answer to your question makes a diagonal line.We looked at the instructions carefully and then used a coordinate grid to help us work out the answer.We found out that the X coordinate is doubled to make the Y coordinate. Thanks for the challenge John we really enjoyed it.
I got a diagonal line across the page.That was challenging.
Fantastic primary 5. Perfectly correct
Further challenges- if you choose to accept them!!
What happens if the y – coordinate is triple the x coordinate? Do we get a similar graph? Do you spot anything that is different (hint- draw the two graphs on the same diagram)?
Very challenging- You’ll need a big diagram for this one
Plot the points (0,0) (1,1) (2,4) (3,9) (4,16) (5,25). Join the points up. What is different about the shape of this graph? What is the connection here between the x and the y coordinates?
