CogAT Practice Test 2nd Grade

Question 1

Which word does not belong in the group?

Accepted Answer

Chair

Answer

The words 'Cat,' 'Dog,' and 'Bird' are all types of animals, representing living creatures. 'Chair,' however, is an inanimate object used for sitting. Therefore, 'Chair' is the word that does not fit the category of living creatures that the other words represent.

Question 2

What number comes next in this analogy?

2 → 4 : 3 → ?

Accepted Answer

Answer

The analogy follows a pattern where the second number is 2 raised to the power of the first number. For the first pair, 2 raised to the power of 2 (2^2) equals 4. Applying this same rule to the second pair, 2 raised to the power of 3 (2^3) equals 8.

Question 3

Which shape completes the pattern?

Accepted Answer

A circle

Answer

Without the visual pattern provided, it is assumed that the sequence of shapes leads to a circle as the next logical element. This could be due to an alternating pattern of shapes, a repeating sequence, or a progression where a circle is the expected continuation, making option D the correct completion.

Question 4

The _____ shines brightly in the sky during the day.

Accepted Answer

Sun

Answer

The sun is the celestial body that provides light and heat to Earth, and it is prominently visible and shines brightly in the sky specifically during the daytime. The moon and stars are typically visible at night, and clouds obscure rather than shine. Therefore, 'Sun' is the only word that correctly completes the sentence.

Question 5

Which number is missing?

5, 10, 15, __, 25

Accepted Answer

20

Answer

This is an arithmetic sequence where each number increases by 5. Starting with 5, the next numbers are 5+5=10, and 10+5=15. Following this pattern, the missing number is 15+5=20, which is then correctly followed by 20+5=25.
