Numeracy Foundation November 2016 Unit 2 Q1
1.
(a) A map of Anglesey is drawn on the grid below.
Each square on the grid represents an area of 16 km2.
Find the approximate area of Anglesey in km2. [3]
Area of Anglesey is ………………… km2.
(b) There is a coastal path around Anglesey.
Diagram not drawn to scale
Cennydd took 8 days to complete the walk around the coastal path.
He recorded the number of miles that he walked on each of the 8 days.
20, 17, 10, 19, 15, 14, 13, 17
What is the median number of miles walked each day? [2]
| Scheme | Marks | Comments |
|---|---|---|
| Evidence of counting appropriate squares. | M1 | Accept areas of blocks of rectangles. |
| (number of squares) 41 − 50 | A1 | Number of squares in range with no evidence of counting, M1 A1 |
| (approximate area) 656 (km2) to 800(km2) | A1 | FT ‘their number of squares’. Answer in range with no workings, M1 A1 A1 |
| Scheme | Marks | Comments |
|---|---|---|
| 15, 17 identified as middle two numbers. OR 10, 13, 14, 15, 17, 17,19, 20 | M1 | For identifying the correct TWO middle numbers OR for arranging the 8 numbers in ascending or descending order. |
| Median= 16 (miles) | A1 | C.A.O. Unsupported 16 gets M1, A1. |
