Summary: These math games are designed for use after a unit is completed on solving equations and/or probability. The first game is designed for pre-algebra students to use their equation solving skills to complete the worksheets and try to get as many points as possible in the time allowed. The second game is designed for algebra students who have an understanding of probability to compete with other students in the classroom. These games can be modified for many math and science topics as well as other subjects.Subject:

Grade Level:
Target Grade: 8th
Upper Bound: 8th
Lower Bound: 7th
Time Required: one class period
Activity Team/Group Size: groups of 3-4 (can also be done individually)
Materials:
HYPERLINK "../Math%20Mania%20Game%20(1%20and%202%20step%20equations).doc" Math Mania Equation game
HYPERLINK "../Math%20Mania%20Game%20(probability).doc" Math Mania Probability game
Expendable Activity Cost Per Group [in dollars]: printing costs of the worksheets
Lesson Introduction / Motivation: These games should be used after the students have been taught the subjects and have mastered the TEKS listed above. Tell the students they will be using their newly gained knowledge in a game to determine who has mastered these concepts the best in the class. As another incentive, have a prize for the winning team.
Lesson Plan: Pass out a packet of each set of questions to the individual groups. Have all of the groups start at the same time and pull out the first worksheet. When the students are done, they will bring the worksheet up to the teacher for grading using the answer keys provided. The teacher will either give ten points or find a wrong answer and the students can return to their seats and figure out the problem for five points for the first time or one point for the second time. Depending on the capabilities of the students the teacher may chose to tell them specifically where the error is or just that an error has been made to teach students to find their own mistakes.
After the first worksheet is completed, the students may pull out the next sheet and continue in the same way until all the worksheets are completed or until time runs out. Assessment:
Use the answer keys provided to check the problems for accuracy. If the problems are all completed correctly, the student(s) will receive 10 points for that sheet. If the student gets all of the problems correct on the second try, the student will receive 5 points for that sheet. If the student gets all of the problems correct after three tries, they will receive 1 point for that worksheet. After that, the student needs to continue on to the next sheet. The student or students with the most points at the end of the game wins the Math Mania Challenge.
Prerequisites for this Lesson:
For the equation problems, the students should know order of operations and how to solve for x. They need to be able to multiply, divide, add and subtract positive and negative numbers, and express answers as fractions.
For the probability problems, the students need to know how to solve simple and compound events. They need to know how to use probabilities to make predictions on the possibility of a certain event occurring.
Lesson Scaling:
Allow the students to work in groups to solve the problems. If the amount of problems is overwhelming, only use the first five worksheets instead of all nine or ten that are available.
