In most elementary school math curricula, 3rd Grade is a crucial year. Students are expected to perform both long and short addition, subtraction, multiplication, and division. Number sense and geometric concepts introduced in grades K-2 are taught more formally, and presented as both number and word problems.

Help your third grader improve his or her understanding of 3rd grade math topics with our 3rd Grade Math Basic Pack. This pack is designed to enrich your child’s knowledge whilst covering an array of word problem topics including calculating arithmetic, distances, work rate, and geometry. The pack can be used either for extra practice or enrichment. Solutions including thorough explanations are provided for all questions. Concepts are presented in study guides, which also provide tips for solving different kinds of math problems. Topics covered include:

- Coins & Money
- Computation
- Math Sequences
- Place Value
- Price Lists
- Equations
- Estimation & Measurement
- 4 Operations
- Geometry
- Numbers & Operations
- Sequences
- Various Problems
- Word Problems

TestPrep-Online provides 204 questions and four math study guides for 3rd grade, which may also be used as enrichment for CogAT Level 9. Questions are divided into drills by topic so you can develop a practice plan for your child to strengthen his/her weaknesses or provide enrichment in topics that may not have been covered fully in the classroom. Drills can be practiced or reviewed any time, anywhere. The materials provided in the Prep Pack can serve as a basis for real-world practice, especially for money and measurement skills that involve tangible objects.

The drills and study guides provided in the 3rd Grade Math pack can be used for a variety of purposes, including:

- Reviewing and reinforcing concepts that were difficult for your child in the classroom
- Enriching classroom instruction with more difficult questions at a higher level
- Preparing for classroom, state, and gifted education tests
- Maintaining skills during school vacations or extended absences
- Supporting a homeschool curriculum

With a 12-month license, you'll be able to use the materials to enhance your child's education all year long, covering and reviewing various topics as necessary.

1. What number is missing from the sequence?

420 530 640 750 _?__

A. 830

B. 840

C. 850

D. 860

The correct answer is (D).

In order to solve this problem, find the common difference between each pair of numbers next to each other in the sequence:

The common difference between each number in this sequence is +110.

Therefore, the number missing from the sequence is:

750 + 110 = 700 + 100 + 50 + 10 = 860

Thus, the correct answer is (D).

2.

3. Which number is greater than 397 by 483?

A. 860

B. 870

C. 872

D. 880

Solutions with Explanations

1. The correct answer is (D).

In order to solve this problem, find the common difference between each pair of numbers next to each other in the sequence:

The common difference between each number in this sequence is +110.

Therefore, the number missing from the sequence is:

750 + 110 = 700 + 100 + 50 + 10 = 860

Thus, the correct answer is (D).

2.

To solve this problem, sum the value of the coins and bills that appear in the picture. From left to right, there is a one-cent coin (penny), another one-cent coin, a ten-cent coin (dime), a one-dollar bill, a five-dollar bill, and another one-dollar bill:

$1 + $5 + $1 + 1¢ + 1¢ + 10¢ = $7 + 12¢ = $7 + $0.12 = $7.12.

Thus, the correct answer is (A).

3.

The correct answer is (D).

There are two ways to solve this problem. The first way is to use vertical addition:

Another way is to separately add the hundreds, tens, and ones and then sum the results:

397 + 483 = 300 + 400 + 90 + 80 + 7 + 3= 700 + 170 + 10 = 880. Thus, the correct answer is (D).
