Example Questions

Example Question #1 : Map 2nd Grade Math

Solve:

 

 

 

\(\displaystyle \frac{\begin{array}[b]{r}75\\ +\ 10\end{array}}{ \ \ \space}\)

Possible Answers:

\(\displaystyle 80\)

\(\displaystyle 75\)

\(\displaystyle 85\)

 

\(\displaystyle 70\)

Correct answer:

\(\displaystyle 85\)

 

Explanation:

When we add \(\displaystyle 10\) to a two digit number, the only number that changes in our answer is the tens position, and it will always go up by \(\displaystyle 1\). Mentally, we can add \(\displaystyle 1\) to the number in the tens place to find our answer. 

\(\displaystyle 7+1=8\)

\(\displaystyle \frac{\begin{array}[b]{r}75\\ +\ 10\end{array}}{ \ \ \ \space85}\)

Example Question #2 : Map 2nd Grade Math

David is \(\displaystyle 23\textup{ inches}\) taller than Alison. Alison is \(\displaystyle 53\textup{ inches}\) tall. How tall is David? 

Possible Answers:

\(\displaystyle 80\textup{ inches}\)

\(\displaystyle 84\textup{ inches}\)

\(\displaystyle 82\textup{ inches}\)

\(\displaystyle 76\textup{ inches}\)

Correct answer:

\(\displaystyle 76\textup{ inches}\)

Explanation:

This is an addition problem because we have the difference in height from the question. Alison is \(\displaystyle 53\) inches tall and David is \(\displaystyle 23\) inches taller than her, \(\displaystyle 23\) is our difference. We can add our difference to Alison's height to find out how tall David is. 

\(\displaystyle \frac{\begin{array}[b]{r}53\\ +\ 23\end{array}}{ \ \ \ \space 76}\)

Example Question #3 : Map 2nd Grade Math

Add:

\(\displaystyle \frac{\begin{array}[b]{r}51\\ +\ 12\end{array}}{ \ \ \space}\)

Possible Answers:

\(\displaystyle 65\)

\(\displaystyle 64\)

\(\displaystyle 63\)

\(\displaystyle 66\)

Correct answer:

\(\displaystyle 63\)

Explanation:

When we add two digit numbers, we start by adding the numbers in the ones place.

\(\displaystyle \frac{\begin{array}[b]{r}5{\color{Red} 1}\\ +\ 1{\color{Red} 2}\end{array}}{ \ \ \ \ \ \space3}\)

Next, we need to add the numbers in the tens place. 

\(\displaystyle \frac{\begin{array}[b]{r}{\color{Red} 5}1\\ +\ {\color{Red} 1}2\end{array}}{ \ \ \ \ \space63}\)

The final answer is \(\displaystyle 63\)

Example Question #1 : Numbers And Operations

What digit is in the hundreds place? 

\(\displaystyle 708\)

Possible Answers:

\(\displaystyle 7\)

\(\displaystyle 1\)

\(\displaystyle 0\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 7\)

Explanation:

For three-digit numbers, there will be a ones place, a tens place, and a hundreds place. 

The digit in the ones place will always be the first number on the right, the tens place will be directly to the left of the ones place, and the hundreds place will be directly to the left of the tens place. See the diagram below. 

1

For the number \(\displaystyle 708\), the \(\displaystyle 8\) is in the ones place, the \(\displaystyle 0\) is in the tens place, and the \(\displaystyle 7\) is in the hundreds place. 

\(\displaystyle 7\) is the correct answer. 

Example Question #2 : Numbers And Operations

For the number provided, what digit is in the ones place? 

\(\displaystyle 684\) 

Possible Answers:

\(\displaystyle 4\)

\(\displaystyle 6\)

\(\displaystyle 3\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 4\)

Explanation:

For three-digit numbers, there will be a ones place, a tens place, and a hundreds place. 

The digit in the ones place will always be the first number on the right, the tens place will be directly to the left of the ones place, and the hundreds place will be directly to the left of the tens place. See the diagram below. 

1

For the number \(\displaystyle 684\), the \(\displaystyle 4\) is in the ones place, the \(\displaystyle 8\) is in the tens place, and the \(\displaystyle 6\) is in the hundreds place. 

\(\displaystyle 4\) is the correct answer. 

Example Question #3 : Numbers And Operations

What is the missing number?

\(\displaystyle 310\)\(\displaystyle 320\)\(\displaystyle 330\), __________, \(\displaystyle 350\)

Possible Answers:

\(\displaystyle 340\)

\(\displaystyle 360\)

\(\displaystyle 335\)

\(\displaystyle 331\)

Correct answer:

\(\displaystyle 340\)

Explanation:

This series is counting up by \(\displaystyle 10\)

\(\displaystyle 310+10=320\)

\(\displaystyle 320+10=330\)

\(\displaystyle 330+10={\color{Magenta} 340}\)

\(\displaystyle 340+10=350\)

When counting by \(\displaystyle 10\)\(\displaystyle 340\) is between \(\displaystyle 330\) and \(\displaystyle 350\)

Example Question #5 : Map 2nd Grade Math

Why is this shape a circle? 

Screen shot 2015 07 21 at 2.57.52 pm

Possible Answers:

Because its color is blue

Because it is small

Because it is a flat shape

Because it is a round, closed shape

Correct answer:

Because it is a round, closed shape

Explanation:

A circle is a round shape, with no sides or edges. 

Though a circle is a flat shape, there are many other flat shapes. For example, a square, triangle, rectangle, etc. So this is not the best answer. Also, the color and the size of a shape does make determine the shape type. 

Example Question #6 : Map 2nd Grade Math

Select the shape that has only \(\displaystyle 5\) sides. 

Possible Answers:

Hexagon

Square 

Triangle

Pentagon
