Number Puzzles: Sample Question
CogAT Level 10 Number Puzzle Question
2 + 10 = ? X 4
Correct Answer: B
Explanation: The first two numbers add up to 12 (10+2). Therefore, we need to find a number (to insert instead of the question mark) that multiplies with 4 to create a total of 12.
The only number that can be multiplied by 4 to make 12 is 3. Therefore, B is the correct answer.
CogAT Level 5/6 Number Puzzle Question
Correct answer: A
In the truck on the top row, there are 10 balls. In the truck on the bottom row, there are four balls in one compartment and two balls in another.
Your child needs to figure out how many balls are needed in the compartment with the question mark so that both trucks (top and bottom row), have the same amount of balls.
We can see that four balls are needed in order to make a total of 10 balls in the truck on the bottom row, because 4 balls from one compartment plus 2 balls from the other compartment results in a total of 6 balls (4+2=6), and we need four more balls in the train to have 10 balls in total (6+4=10).
The only answer that shows 4 balls is option A.
Number Puzzles:Tips and Strategies
This question type requires your child to solve basic math equations, so practice with numbers and problem solving is essential.
Make sure your child understands the meaning of “equal,” since the object is to supply the missing piece of information that will make two provided equations equal to one another. Buy a workbook that focuses on basic mathematical skills like addition, subtraction, multiplication, and division.
Practicing multiplication facts could help improve your child’s accuracy and speed. You can also teach your child to approach the question by “plugging in” the answer choices and solving to see if the result is equal to the other equation in the question.
Of course, it is also important to work with practice questions in order to familiarize your child with the content and structure of the actual test.
Ask her to explain her reasoning for each question that she answers. This will allow you to praise and reinforce strong problem solving skills for correct answers and address misconceptions for incorrect answers.
