Activity 11.4
a) The point A is the intersecting point of the crossing bar number 2 and the post number 4 .
b) The point B is the intersecting point of the post number 5 and the crossing bar number 3.
11.4 Location of a point on a grid
Activity 11.5
– Count and number all posts from the first by using numbers: 1, 2, 3, 4, 5, 6.
– Count and number all crossing bars from the first by using numbers: 1, 2, 3, 4, 5, 6.
Then;
- Show a point A at the intersection of post number 4 and crossing bar number 3.
- Show a point B at the intersection of post number 5 and crossing bar number 6.
The answer is on this grid.
I have learnt that:
When locating a point on a grid, we start by the number of posts and then the number of crossing bars.
Example:
The point A is located at the intersection of post number 4 and the crossing bar number 3.
Activity 11.6
1 . Draw a grid with 5 posts and 5 crossing bars.
2. Put a point on:
a) The post number 3 and the crossing bar number 4
b) Post number 4 and the crossing bar number 5 c) Post number 2 and crossing bar number 3
3. Draw a grid with 7 posts and 7 crossing bars.
4. Draw a grid with 8 posts and 8 crossing bars.
Show the point A located at the post number 5 and the crossing bar number 4.
Put the point B at the post number 7 and the crossing bar number 6.
