Fractions may be challenging, but it is important you develop a good grasp of fractions concepts as these lessons are related to numbers, decimals, percentages, measurement, and ratio and proportion.
In order to get a better understanding of fractions, here are some activities you can do:
- Cut equal strips of paper or show by folding. Cut or fold the first strip in half, the second in thirds, the third in fourths, and so on.
- Draw a number line on a piece of paper. Draw the line 2 cm long. Show by number the points 1, ¼,½, ¾, 1, and so on.
- On a geoboard, show various shapes. Then show the following fractions: ¼,½, and ¾.
- Use grids on a paper to draw various shapes and show the following fractions: ¼,½, and ¾.
- Use pattern blocks to show the following fractions: ¼,½, and ¾.
- Draw various shapes, triangle, rhombus, square, rectangle, pentagon, etc. Show the fractions: ¼,½, ¾, etc. Verbally explain the the fractions.
- Compare and show equal fractions.
The activities above would help you understand the representation of equal parts and the how it is represented.
