__Simplifying Radicals With Go-Fish__1) In groups of 3 or 4, take a deck of cards and remove all the jokers and face cards (Jacks, Queens, and Kings) from the deck.

**For this activity ignore the suits of the cards.**2) Deal out all the cards, one at time, to each person.

3) Fill out the chart as follows:

a. Write down the

**square root**of the**product**of all your cards, as an exact number. (Aces = 1)b. Write the decimal approximation, to 2 decimal places

4) Put your pairs together, and keep the single cards separate.

5) Fill out the chart as follows:

a. The product of

**each**pair. (IE if you have 2 3s and 2 4s, you would multiply 3 by 4)b. The

**square root**of the**product**of the single cards, as an exact number.6) Multiply the product of the pairs, to the square root of the remaining cards, and round to 2 decimal places.

7) Repeat for 10 hands.

8) Answer the questions on the back page.

9) Explain, why both ways are giving you the same decimal values.

9) Explain, why both ways are giving you the same decimal values.

__Example:__Jason was dealt a four card hand which consisted of an 8, 3, 5, and another 8. He filled in the first row and shown.

Hand Number | Square root of the Product | Decimal, to 2 decimal places | Product of the pairs. | Square root of the remaining cards | Product of the pairs and root of the remaining cards |

Example | 30.98 | 8 | 30.98 | ||

1 | |||||

2 | |||||

3 | |||||

4 | |||||

5 | |||||

6 | |||||

7 | |||||

8 | |||||

9 | |||||

10 |

If you are going to use this, do NOT do 10 hands...wow what was I thinking? I thought 10 would illustrate the pattern, but 10 just killed the desire to complete any extra problems.

ReplyDeleteNext time through, I will asking for only 5 hands

This blog is helpful to solve the problems of simplifying radical equations . You can also solve easily by using simplifying radicals calculator .
