- 1. th 4 Grade Math Number Sense and Operations Jessica Corriere & Robert Richards
- 2. Number Sense, decimals, fractions, and negative numbers, operations and factoring
- 3. This PowerPoint is a th sample of the book, 4 Grade Math
- 4. What is 42,385,099 rounded to the nearest hundred thousand? A. 40,000,000 B. 42,385,100 C. 42,400,099 D. 42,400,000
- 5. How to solve Understand which numbers are significant. When rounding numbers in this problem it is important to remember that if the number to the right of the number to be rounded is 5 or more you round up one place, if less than five the number to the right goes to zero. For example if we wanted to round to the nearest significant hundred, 150 would round up to 200, while 149 would round down to 100. In this problem it asks to round to the nearest hundred thousand, the 42 million stays as is. The three hundred eight five thousand gets rounded up to 400,000 and the 099 gets dropped so the fully rounded number to the nearest hundred thousand becomes 42,400,000 Choice D has the correct answer
- 6. Which fraction represents the largest part of a whole? A. 1/8 B. 1/4 C. 1/3 D. 1/2
- 7. How to solve Understand when whole numbers are split into parts. Fractions contain a numerator, which is the top number and the denominator which is the bottom number. The larger the bottom numbers is more parts the to the whole number. Think of a pizza divided into 8 pieces. Each of those 8 pieces is smaller than if the pizza was sliced into 4 pieces. If the original pizza was cut in half that is ½, there would be 2 larger slices of pizza. Much larger than a pizza that had been cut into 8 pieces. Looking at the possible choices of answers the answer with the smallest denominator is choice D with the answer of 1/2 Choice D has the correct answer
- 8. Which fraction means the same as 0.25? A. 25/100 B. 2/4 C. 0.24/100 D. 2/7
- 9. How to solve Understand how to convert decimals to fractions and reduce. The decimal to convert is 0.25. The number to the right of the decimal point is the tenths place and to the right of that is the hundreds place. Think of coins. Ten cents would be written as $0.10 twenty-five cents would be written as $0.25. Thinking of a two place decimal as part of a hundred you can write 0.25 as 25/100. Choice A has the correct answer
- 10. The numbers in the pattern increase by the same amount each time, what are the next 4 numbers in the pattern? 18, 28, 38, 48, 58 A. 23,24,25,26 B. 60,70,80,90 C. 68,78,88,98 D. 0,6,12,18
- 11. How to solve Understand patterns in counting. To determine the pattern you find how much each number increases from the prior number. Subtract 18 from 28, 28 – 18 = 10, Now check the next number Subtract 28 from 38, 38 – 28 = 10, Now try another set Subtract 38 from 48, 48 – 38 = 10 And finally subtract 48 from 58, 58 – 48 = 10 Each of the numbers increases by 10 from the prior number and has an 8 as the second number. Looking at the possible choices, only choice C has four numbers that increase by ten with each number and each end in 8 as the second number. Choice C has the correct answer
- 12. Algebra and functions
- 13. Which number is symbolized by n? 6 x n = 48 A. 6 B. 7 C. 8 D. 9
- 14. How to solve Understand how to solve for the unknown. 6 x n = 48 Both sides must be treated the same Divide both sides by 6 to get the n alone on one side (6 x n) 6 = 48 6 n = 48 6 n=8 Choice C has the correct answer
- 15. Solve the problem shown below, (22 - 1) A. 7 B. 8 C. 9 D. 10 (5 - 2) =
- 16. How to solve Understand the orders of operation. (22 - 1) (5 - 2) = The orders of operation are always Multiply, Divide, Add then Subtract You can remember that using the phrase. My Dear Aunt Sally Take care of operations in the parentheses first in the same order (22-1) (5 - 2) = (21) (3) = 21 3 = 7 Choice A has the correct answer
- 17. Measurement and Geometry
- 18. What is the perimeter of a rectangle that has a length of 9 feet and a width of 7 feet? A. 81 feet B. 63 feet C. 32 feet D. 25 feet
- 19. How to solve Understand how to calculate perimeters. Calculate the perimeter by using the formula P = 2l + 2w P = (2 x 9) + (2 x 7), so P = 18 + 14, so P = 32 Choice C has the correct answer
