The pattern is increasing by 1 more each time2+1=33+2=55+3=88+4=1212+5=17

• Marcy drew a pattern for her little sister to finish

qweerqweerqweerWhat 3 shapes come next in the pattern?A. qweB. WeeC. eeeD. wee

• What is the next number in this pattern?59, 52, 44, 35, _____

A. 26B. 25C. 28D. 27

• AnswerB. 25The next number in the pattern is 25.The rule is subtract 1 more each time.59-7=5252-8=4444-9=3535-10=2525-11=1414-12=2

• What fractions comes next in this pattern?, 2/4, 4/8, 8/16, ?/?

16/3616/3212/3211/25

• AnswerB. 16/32The pattern is multiply the numerator and denominators by 28 (x2) = 1616 (x2) = 32

• Which two numbers will be next in the pattern?6, 11, 16, 21, ____, ____

23, 2825, 3126, 3026, 31

• AnswerD. 26, 31 You found each number by adding 5.The next numbers are 26 and 31.

The pattern is that each number is the number before it.

• Becky has 3 times as many dolls as her friend Gwen. Let g equal the number of dolls that Gwen has.How would you express the number of dolls Becky has?g-3g/3g+3gx3

• AnswerD. gx3Becky has 3 times the number of Gwens dolls.Gwens doll is multiplied by 3Beckys dolls equals gX3

• The number of dogs in the United States is 6 times the number of deer. Let b express the number of deer.Which expression shows the number of dogs?b/66/bbx6B+6

• AnswerC. bx6There are 25 million deer in the US. There are 6 times as many dogs.6x25 million= 150 millionThere are 150 million dogs

• Sue noticed that 13 students brought lunch to school. Let b represent students that buy their lunch.Which expression shows the total number of students in Sues class?b+1313xbb-13b+b

• Answerb+13b= students who buy lunch.13 = students who bring lunchb+13 is the expression that shows the total number of students

• Dante is twice as old as her cousin, Angela. Let a express Angelas age.How do you express Dantes age?A + 22 x aA - 2a/2

• AnswerB. 2 x aDante is twice as old or two times as old as Angela2 x a = 2 times Angelas age2 x a= Dantes age

• Holly had \$25.00 to spend at the book fair. She purchased 2 books for \$11.25 each.Which expression can be used to find how much money Holly had left?\$25.00- (\$11.25 2)\$25.00 (\$11.25 x 2)\$25.00 (\$11.25 + 2)\$25.00/ (\$11.25 x 2)

• AnswerB. \$25.00 (\$11.25 x 2)

Holly had \$25.00.2 books for \$11.24 each: \$11.25 x 2Subtract the cost of 2 books from \$25.00

• Mrs. Clark had a budget of \$75.00 for the class play. She needs to buy 3 cowboy hats which cost \$5.00 each and 12 flags which cost \$1.00 each. She must spend \$25.00 for balloons.Which number sentence shows how much money is left for sodas?(\$15.00 + \$12.00 + \$25.00) - \$75.00\$75.00 (\$15.00 + \$12.00 + \$25.00)\$75.00 (3 + 12)\$75.00 (\$5.00 + \$12.00 + \$25.00)

• AnswerB. \$75.00 (\$15.00 + \$12.00 + \$25.00)Her budget is \$75.00. Her purchases are subtracted from \$75 to find the amount left.Purchases 3 cowboy hats x \$5.00 = \$15 12 flags x \$1.00 = \$12 balloons = \$25\$52\$75.00 - \$52.00 = \$23.00 left
