1. | Find the colored blocks labelled for this activity. |
2. | Sort according to color. |
3. | Place the blocks side by side on the sheet of paper to make a circle. Be sure to keep the same colors together. |
4. | Draw a circle just outside the ring of blocks. |
5. | Leaving the blocks in place, make a dot as close to the middle of the circle as possible. |
6. | Next draw a line between each color from the point you drew at the centre of the circle to the circle you have drawn around the blocks. |
7. | a) | Knowing that you started with 32 blocks, give the fraction of each of the colors of blocks. |
| b) | Explain why the total of all the blocks can be represented as 32.
32 |
| c) | What is the fraction that represents theblocks and the blocks? Explain your strategy. |
| d) | What is the fraction that represents the, the and the blocks? Explain your strategy. |
8. | Next , color each section of the circle to represent the color of blocks it contains. Remove the blocks and label your circle graph. |
9. | Look at the chart on the other side of this card. This is a circle graph that represents the number of colored blocks:
pink green blue orange yellow |
| a) | Estimate what fraction of the total number of blocks is each color. Can you determine how many blocks of each color there are? |
| b) | What fraction represents the total number of blocks? Explain how this affects your estimates for a). |
