Lesson Plan MathRace Author [Megan Weber]
NE Standards:8.2.4 – Student will apply order of operations to solve problems with and without the use of technology. Objectives: To increase student speed and accuracy in adding and subtracting positive and negative integers Assessment: 80% average across four races Provision for special needs: Extended time for students who need it, MH: Mi students may only complete 2 races Materials: Paper, pencil, diskette, calculator, computer Vocabulary: Positive Number, Negative Number, Add, Subtract, Double Negative Procedures: Springboard Talk to students about having $5 in the bank and then taking $10 out…..this is an example of how we get negative numbers. I also put a masking tape number line on the floor so I can “walk out” addition and subtraction problems after I put them on the board. Activities: T: Write several simple problems on the board. I will “walk out” the problems on the number line. I then show students how to use their calculators – they must know the difference between the subtract symbol and the negative symbol. I put several more problems on the board and have them work them out on their calculators before I walk them out on the number line. Small worksheet given to reinforce concept. S: Students practice at their desks as directed. Students will then be taken to the computer lab, where they will be walked through starting the game. Each student will record their percent correct for four games, and will bring the sheet to me to initial when they are complete. Closure: We will discuss which problems in the races were harder than others, and what types of errors they were making (calculator errors, copying the problem errors, etc). We will then look at a few more complex problems that I will “walk out” on the number line and talk about the importance of understanding negative numbers as they relate to their checkbooks, the weather, etc. References: Algebra I, Volume I, 2001 Edition, Glencoe McGraw-Hill Reflection: This plan has worked well for my students. They enjoy using the math game and it motivates them to increase their speed and accuracy. They take quite a bit of pride in their scores and they tend to test out of the unit with good scores.
