ACTIVITY SHEET 1
EXERCISE 1 Everyday Fractions
List some measurements in everyday situations that involve
fractions.
EXERCISE 2 Pattern Blocks
Pattern blocks are used to model fractions as part of a whole.
When completing the following exercise, keep in mind what the whole is in each
case.
| Color
Key: |
Hexagon =
Yellow
Rhombus = Blue
Trapezoid = Red
Triangle = Green |
| (a) |
If a hexagon is 1,
what is a triangle? a rhombus? a trapezoid? |
| (b) |
If a hexagon is 1, show 2/3 ,
4/6 and 7/6. |
| (c) |
If a trapezoid is 1, what is a
triangle? a rhombus? a hexagon? |

EXERCISE 4 Building Patterns
Use pattern blocks to model each of the
following.
| (a) |

that is 1/3 green and 2/3 red. |
| (b) |
Build a parallelogram that is
3/4 blue and 1/4 green. |
| (c) |
Build a parallelogram that is
2/3 blue and 1/3 green. |
