## Grade 3 Mathematics Answer Key

**
1. Answer: B
**
The number, 860,002 has an 8 in the hundred-thousands place, a 6 in the ten-thousands place, a 0 in the thousands place, a 0 in the hundreds place, a 0 in the tens place, and a 2 in the ones place. The 860 written in front of the comma represents, "Eight hundred sixty thousand." The 2 in the ones place represents, "Two." Therefore, the number is read, "Eight hundred sixty thousand, two."

**
2. Answer: D
**
The numbers: 608, 458, 452, 381, 321, and 294 are written in order from greatest to least. An examination of the numerals in the hundreds place reveals that 608 is the greatest and 294 is the least. The numbers, 458 and 452, are greater than the numbers, 381 and 321, based on the value of the digits in the hundreds place. An examination of the numerals in the ones place, since both the digits in the hundreds and the tens places are the same, allows you to compare 458 and 452, which shows 458 to be the larger number. An examination of the numerals in the tens place allows you to compare 381 and 321, since the digits in the hundreds place are the same, which shows 381 to be the larger number. None of the other choices show the numbers in descending order.

**
3. Answer: D
**
The total number of feet he ascended can be determined by adding 482 feet and 362 feet. The sum of 482 and 362 is 844. Thus, he ascended 844 feet in all.

**
4. Answer:
**
This is a simple multiplication problem which involves carrying the excess (greater than a single digit) to the next column. Start with the 8 and multiply each digit above: 8 x 6 = 48. Write down the 8 and place the 4 on top of the 9. Multiply 8 x 9 to get 72. Add in the 4 to get 76. Write down the number 76 and the product is 768.

**
5. Answer: C
**
Each number is 8 more than the previous number, which means that the next number can be found by adding 8 to the previous number. Thus, the fifth number is 353, the sixth number is 361, the seventh number is 369, and the eighth number is 377.

**
6. Answer: B
**
Since a die has one of each number, from 1 to 6, she is equally likely to roll any of the six numbers. The possibility of rolling one of these numbers is no more or less than the possibility of rolling another of these numbers. Thus, she is equally likely to roll a 3 or a 6.

**
7. Answer: C
**
If each rectangle has a length that is 5 cm more than that of the previous rectangle, the lengths of the 3rd rectangle through the 11th rectangle can be found by adding 5 cm to the length of the second triangle and continuing for each next rectangle. So, the lengths of the rectangles will be as follows: 16 cm, 21 cm, 26 cm, 31 cm, 36 cm, 41 cm, 46 cm, 51 cm, and 56 cm.

**
8. Answer: D
**
The more fish there is of a certain color the more likely it is that the color of fish is scooped. With more orange fish than striped fish in the bowl, he is more likely to scoop an orange fish than a striped one. There are equal amounts of striped and blue fish, so one is not more likely than the other. There are more orange fish than blue fish, so he is more likely to scoop an orange fish than a blue one.. Finally, the number of striped and blue fish is the same - so they are equally likely to be scooped compared to each other. Thus, Choice D is the only true statement.

**
9. Answer: C
**
In order to find the amount donated the following year, you multiply the amount donated the previous year by 3. Thus, the amount donated the second year was $6 ($2x3). The amount donated the third year was $18 ($6x3). The amount donated the fourth year was $54 ($18x3). The amount donated the fifth year was $162 ($54x3).

**
10. Answer: C
**
The item priced at $4.58 can be rounded to $5. The item priced at $6.22 can be rounded to $6. The item priced at $8.94 can be rounded to $9. The sum of 5, 6 and 9 is 20. Thus, the best estimate is $20.
