Grade 2 Math: 10 Free Practice Questions

Answer: 1 cup
About 1 cup is a reasonable amount for a juice box. The other choices are far too large or far too small for a container of that size. When estimating capacity, compare the container to ones you know, like a milk jug (1 gallon) or a drinking glass (1 cup).

Answer: 1 whole and 5 tenths
In 1.5, the 1 shows one whole and the 5 shows five tenths. The digit to the left of the decimal point, 1, is in the ones place and shows 1 whole. The digit to the right, 5, is in the tenths place and shows 5 tenths. So 1.5 means 1 whole and 5 tenths. Students may ignore the decimal point and read 1.5 as fifteen.

Answer: 3
3 of the small triangles point in the same direction as the large triangle. The problem states there are 4 small triangles total: 1 points the opposite way (in the middle) and the rest point the same way as the large triangle. Subtract: 4 − 1 = 3 triangles point the same way. Students may count all 4 small triangles as pointing the same way, ignoring the middle triangle that points oppositely.

Answer: 53
5 tens and 3 ones make the number 53. 5 tens equal 50, and 3 ones equal 3. Add 50 + 3 = 53. Students frequently reverse the digits, writing 35 instead of 53, confusing which digit represents tens versus ones.

Answer: 8 - 3 = 3 - 8
8 - 3 = 5, but 3 - 8 does not equal 5. Even though the same two numbers are used, changing the order in subtraction changes the result, so this equation is false.

Answer: 9
18 − 9 = 9. 9 + 9 = 18, so 18 − 9 = 9. Adding instead of subtracting gives 27; miscounting gives 8 or 10.

Answer: 0.4
The pattern counts up by one tenth each time, so the next number is 0.4. Find the rule: 0.1 to 0.2 is an increase of 0.1, and 0.2 to 0.3 is also an increase of 0.1. The rule is add one tenth. Apply the rule: 0.3 + 0.1 = 0.4. Students append a digit to make 0.31 instead of adding one tenth to the tenths place.

Answer: Chocolate
Chocolate has the most symbols with 6, which is more than vanilla's 3 and strawberry's 2. Count each row: Chocolate = 6 symbols, Vanilla = 3 symbols, Strawberry = 2 symbols. Compare the totals: 6 is the greatest value. Students may misread the graph and select vanilla or strawberry by miscounting symbols or by confusing which row belongs to which flavor.

Answer: 800 + 10 + 5
815 has 8 hundred(s), 1 ten(s), and 5 one(s), so its expanded form is 800 + 10 + 5.

Answer: 74
In the ones column, 8 + 6 = 14, so regroup 1 ten into the tens column. Then 5 + 1 + 1 (regrouped ten) = 7 tens. The sum is 74.
