  1. ISAT Mathematics Review

  2. Area What is the area of the triangle pictured below? • 18 in² • 6 in² • 9 in² • 12 in² *Remember area of a triangle is 1/2xbxh* Answer: c. 9 in² A=(1/2)x3x6=9

  3. *Rememberarea of a RECTANGLE is bxh* Answer: d. 21 in² A=7x3= 21 in² What is the area of the rectangle below? 20 in² 17 in² 10 in² 21 in² AREA 7 3

  4. AREA • What is the area of this square? • 32 cm² • 16cm² • 64cm² • 48 cm² • Rememberarea of a SQUARE is simply sxs • Answer: c. 64 cm² • A= 8x8= 64 cm² 8 8

  5. Remember perimeter of a polygon is the sum of the sides Answer: d. 28 ft P= 8+5+6+4+1+4= 28ft What is the perimeter of the figure below? 26 ft 18 ft 23 ft 28 ft Perimeter 8 ft 5 ft 6 ft ? ? 4 ft

  6. Remember perimeter of a square is 4 x side length Or in other words, Perimeter of a square =s+s+s+s Answer: c. 40 m P= 4 x 10 = 40 m What is the perimeter of this square? a.100 m b. 20 m c. 40 m d. 50 m Perimeter 10 m

  7. Mean, Median, and Mode • Answer: c. 91 • Mean is normal average Add all of the data together (90+87+95+96+93+88+88)=637 Divide by number of things you added together 637/7=91 Beth recorded the highest temperature for seven days 90, 87, 95, 96, 93, 88, 88 What is the mean (average) temperature? • 88 • 90 • 91 • 96

  8. Mean, Median, Mode • Answer: b. 90 • Median is the middle number of the set • Good strategy: • Write your data in order from smallest to largest 87, 88, 88, 90, 93, 95, 96 • What number is in the middle? 90 Beth recorded the highest temperature for seven days 90, 87, 95, 96, 93, 88, 88 What is the Median of the temperatures? • 88 • 90 • 91 • 96

  9. Mean, Median, Mode • Answer: a. 88 • Mode is the number that is repeated most often! • 88 is the only temperature that occurs more than once Beth recorded the highest temperature for seven days 90, 87, 95, 96, 93, 88, 88 What is the mode of the temperatures? • 88 • 90 • 91 • 96

  10. GOOD LUCK! Think hard and do your best!
