Day 1-Basic Math Review

Below is an example of each type of math problem on the Basic Math Review Sheet. You may write the examples on the board, use the LCD projector or overhead projector for students to reference as they work. You could have a student come up to the board to solve the problem and you confirm the correct answer. This would get the students involved in the process.

Adding Decimals-Remind them that they must line up the numbers correctly before adding them.

2.350 + 152.001 + 0.014 + 47 =

2.350

152.001

0.014

47.00

201.365 = 201.4 (Round to the nearest 10th)

Subtracting Decimals

134 – 99.12 =

134.00

-99.12

34.88 = 34.9

Multiplying Decimals

9.326 x 1.2 =

9.326

x 1.2

18652

9326 Add

11.1912 (count 4 decimal places) = 11.2 (round to nearest 10th)

Dividing Decimals

267/1.2 (read 267 divided by 1.2)

= 222.5 (already rounded, this is the answer)

Change from decimal to fraction.

Simply place the number over the number place that it is in then reduce.

0.19 = 19/100

0.6 = 6/10 = 3/5

0.257 = 257/1000

Change from fraction to decimal.

Divide denominator (bottom number) into numerator (top number).

5/6 = 6 into 5 = 0.8333 = 0.8

Print a copy of the Math Conversions Worksheet for each student. Allow them to work on the sheet. Grade the work of students as they turn it in using the key provided. Those that score 90% or better, assign them to work with a student that is having difficulty with the work. Explain to the Peer Tutor that they are to show their “student” the steps to the answer not give them the answer because the goal is to have every student be able to work problems independently in preparation for the quiz at the end of the unit. Allow the students 15-20 minutes to work. Poll the room for those that need assistance. Have a few students come to the board and answer the first few problems. Correct as needed. Instruct students that those not done are to complete the sheet for homework and turn it in at the beginning of class tomorrow.
