June 2015To the Students Taking 7th grade Pre-AP/GT Math at Baines for the 2015-2016 School Year:Next year will be an exciting and challenging year as you take 7th grade Math at the Pre-AP/GT level. The PreAP/GT curriculum in math has been designed to prepare students to take high school credit Honors Algebra in8th grade. In short, you will be learning 4 years of math in 3 years. In order to accomplish this, several 7th gradeconcepts are taught in the 6th grade GT classes and the non-algebra 8th grade concepts are integrated into the 7thgrade Pre-AP/GT classes. The purpose of this packet is to make sure you are as ready to begin the 7th gradeportion of this experience as possible. Some of the important skills you need to have in order to be ready for 7thgrade Pre-AP math include: comparing and ordering fractions, decimals, percents and integers, fractionoperations, decimal operations, adding and subtracting integers with models, squares and square roots, order ofoperations with exponents, measurement concepts of area and composite area, and using Venn diagrams.This packet has been put together with those skills in mind. To help you strengthen and keep your math skillsover the summer, we would like you to complete this packet. If you work one to two pages each week, you'llhave the packet completed by the beginning of the school year. This packet will be your first grade in mathclass. It is due the first full week of school and will be followed with a test over the content in this packet. If youfeel you need extra practice beyond that provided in this packet there are several resources available online or inthe public library.In order to receive credit for this packet, you must show all work. Though graphing calculators will be used inclass, the intent of this packet is to reinforce proficiency in basic skills. No calculators may be used incompleting this packet unless otherwise stated. Answers with no work will receive no credit!We hope you have an enjoyable summer. We look forward to meeting you next year.Sincerely,Baines Middle School Math TeachersShow ALL work where applicable. Complete your work on separate notebook paper if you need additionalspace. Be sure to label each problem with the page and problem number and write your final answer in thepacket.No calculators may be used in completing this packet unless there is a calculator symbol at the top of the page.Answers with no work will receive no credit!If you need to reprint any portion of this packet, go to www.baines7thmath.weebly.com. and click on Pre-AP,Summer packet, and then Pre-AP/GT summer packet.Additional textbook support can be found in the 7th grade online textbook. To access the online textbook, go towww.baines7thmath.weebly.com and click on Resources, Websites, and then textbook.You must enter username-max2tx07 and password: lonestar.If you have any questions during June or August, feel free to contact Renell Green, Pre-AP seventh grade mathteacher, at 281-634-6949 or renell.green@fortbendisd.com (email will have a better response time).1

Objective: Converting fractions, decimals, and percents. To write a decimal as a fraction, divide the numerator of the fraction by the denominator. To change a decimal to a fraction, read the fraction mathematically correct identifying theplace value. Decimals and fractions that have a denominator that is a power of 10 (10, 100,1000, etc.) are read exactly the same.31o 0.31 are equivalent and are both read “thirty-one hundredths.”100To write a fraction as a percent, find an equivalent fraction with a denominator of 100.Instead of writing the denominator of 100, write the value in the numerator with a percentsign.416o 16%25 100 To write a percent as a fraction, write the percent (without the percent sign) as thenumerator and 100 as the denominator. Percent means “per 100.” To write a percent as a decimal, divide the percent by 100 and remove the percent sign. To write a decimal as a percent, multiply the decimal by 100 and add the percent symbol.Convert each of the following values to fractions in simplest form.1. 0.84. 2.257. 70%2. 0.525. 15%8. 135%3. 0.866. 95%9. 1%Convert each of the following values to decimals.510. 21%13. 181911.14. 7%20112. 10 %215. 345Convert each of the following values to percents.719. 0.0622.20720.23. 0.2471021. 0.6624.175016.235017. 734%18. 0.5%25. 0.760126.1827. 5.91Glencoe Grade 7 online textbook – reference chapter 5, sections 5, 6, and 7 and chapter 7, section 7.2

Objective: Compare and Order fractions, decimals, percents, and integers To compare fractions, decimals, percents and integers, rewrite all numbers so that theyare in the same form. For example, if the values are decimals and fractions, rewrite all ofthe values as decimals and compare. To compare fractions, rewrite them so they have common denominators. Another way to compare fractions is to express them as decimals. Then compare thedecimals.Fill in each blank with , , or to make a true sentence.1.45544. 0.3 0.337222. 3 3.255. -3 -53. 250%26. 36%38Order each set of values from least to greatest.7. 0.48, 0.46,8.9209. 99%,113, 23%, 0.4, 0.2,45097, 0.89, , 1.18810. 15 F, -7 F, 32 F, -15 F, -2 F, -27 F11.

Objective: Add and Subtract Fractions Like fractions are fractions that have the same denominator. To add or subtract likefractions, add or subtract the numerators and write the result over the denominator. Simplify if necessary. To add or subtract unlike fractions, rename the fractions with a least commondenominator. Then add or subtract as with like fractions. To add or subtract mixed numbers:o Add or subtract the fractions. Rename using common denominators if necessary.o Add or subtract the whole numbers.o Simplify if necessary.5Example: Find 21 12 .8Add or subtract.

Objective: Exponents, Squares, and Square Roots The exponent tells you how many times the base is used as a factor.o To write 63 as a product of the same factor, 6 is used as a factor 3 times.63 6 6 6o To evaluate 54, find the product of 5 5 5 5 . So, 54 625.o To write 4 4 4 4 4 4 in exponential form, write the base and count the commonfactors. The number of common factors is the exponent. So, 4 4 4 4 4 4 46. The product of a number and itself is the square of the number.o The square of 5 is 25 because 5 * 5 25. The factors multiplied to form perfect squares are called square roots.o Both 7 7 and ( 7)( 7) equal 49. So 49 has two square roots, 7 and -7.o A radical sign, , is the symbol used to indicate the positive square root of anumber.

Objective: Adding Integers with ModelsTo add integers, it is helpful to use a model. When using counters, first draw circles or squares to represent the problem.o To represent a positive unit, draw a small un-shaded circle or square.o To represent a negative unit, draw a small shaded circle or square. Line up negatives and positives so that you can circle “zero pairs.”o ( 1) (-1) 0. We call a positive tile a negative tile a zero pair. “Remove” all zero pairs by either drawing an “X” through them or drawing an arrow. The remaining tiles are the answer.Draw counters or a number line to find the sum of each expression.7. 15 (-10)4. -7 (-7)1. 5 (-8)2. -3 35. -8 108. -11 (-12)3. -3 (-8)6. -7 139. -14 (-13)Evaluate each expression if a -8 and b -4.

Objective: Subtracting Integers with Models When using counters to subtract, first draw circles or squares to represent the firstnumber in the subtraction problem.o To represent a positive unit, draw a small un-shaded circle or square.o To represent a negative unit, draw a small shaded circle or square. Look at the second number and “take away” that many tiles by circling the tiles anddrawing an arrow. IF there are not enough tiles, you must add zero pairs until you have enough of the tilesyou need to take away. By adding zero pairs, you are not changing the value of theoriginal number. The remaining tiles are the answer.Example 1: Find -5 – (-2).Example 2: Find -3 – 2.1. Draw 5 negative tiles.1. Draw 3 negative tiles.2. Circle and “take away” 2 negative tiles.2. You can not remove 2 positive tiles soadd two zero pairs.3. Now you can remove 2 positive tiles.3. There are 3 negative tiles left,so -5 – (-2) -3There are 5 negative tiles left so -3 – 2 -5Subtract. Draw counters to find the difference of each expression.1. 5 – 24. 8 – 137. -3 – 82. 6 – (-7)5. -7 – (-7)8. 10 – 123. 3 – (-2)6. 6 – 119. -8 – (-3)Evaluate each expression if r -4 and s 10 and t -7.10. r – 712. s – (-8)11. t – s13. t – rGlencoe online textbook – reference Chapter 2, section 514. s – t15. r – s12
