Constructing linear equations from real-world applications:

This activity will have students construct and solve linear equations that they derive from their everyday experiences. Students could work in pairs or groups of 3-4.

1. Construct a linear equation in which the solution is the number of apps that you have on your smart-phone. (If you do not have a smart-phone then your solution should be a= 0). The equation should involve at least three arithmetic operations.

For example: 2(a–17)=50 where 'a' represents the number of apps. Pass your paper to one of the classmates in your group. That classmate will solve the equation and verify that the answer is correct.

2. Construct another linear equation. The solution to this equation could be the number of ice-creams eaten by you in the last six months. For this equation, have a variable on each side of the equation.

For example: 6x-22=2x+10 where 'x' represent the number of ice-creams. Pass your paper another of your classmate. That classmate will solve the equation and verify that the answer is correct.

3. Construct another equation in which the solution is the number of holidays you have this semester. The equation could include fractions in the equation.

For example: 8/12 c+15=17 where c represents the number of holidays. Pass your paper to a classmate. That classmate will solve the equation and verify that the answer is correct.

7. Construct a linear equation whose solution is the current price of one kilogram of rice.

For example: 100p– 201 = 188 where p represents price per gallon. Pass your paper to a classmate. That classmate will solve the equation and verify that the answer is correct.

8. Take all four papers and exchange them

with another group. Those

students will solve the

equations and verify that the answers are correct.
