You have a goal to achieve a certain score on this test. We will work with you to identify what you personally need to be successful, and then we will make a plan that works with your schedule to master all these topics by your chosen test day. We know it may be a while since you were successful in math, but together we will master these topics. If you need anything at any time, email us (edMe@myedme.com). We are here to make sure you are successful!
edMe Learning
There are four key topics in Unit 0:
- 0.1 Recognize place value and names for numbers
- 0.2 Perform operations with whole numbers
- 0.3 Round whole numbers and estimation with whole numbers
- 0.4 Solve application problems by adding, subtracting, multiplying, or dividing whole numbers
The key to this unit is understanding numbers. If you can put these numbers on a number line, then you already have a strong foundation.
(If you can divide 2,000 by 40 in your head, you are probably ready for Unit 1. If not, we are happy you can use these fun resources!!)
Choose “Game” in this interactive and play a couple quick games to get familiar again with thinking about hundreds, tens and ones. It shouldn’t take long and you may even have fun!
Quick Walk down Number Name Lane (Unit 0.1)
These number names help us explain numbers like 330,000,050 (“330 million and 50”).
Each digit in the millions and thousands can be said on its own. 600,000 is “six hundred thousand”. 70,000 is “seventy thousand.” And, 8,000 is “eight thousand.” Altogether it is 678,000.
Numbers that have zeroes take more careful consideration. Because there are more place values than numbers in the description it is easy to make a mistake. For example, you know “three hundred five” is 305 but may need to take more time to write “eight hundred twenty thousand, seventy five.” It’s easy to incorrectly write the numbers in order, 8275, but it just takes an extra second to use the place value words to correctly write: 820,075.
You can click on this picture to have even more real-world numbers to practice. The U.S. population here is “three hundred thirty million, eighty-five thousand, and two hundred thirty seven.” How would you say the world population? How about Mexico’s population?
You can write any number in words, and should be able to write the number described in words.
Using Whole Numbers
Many people need a refresher on these types of number facts.
Here are the same facts presented in a way that is easier to skip count.
The facts with 1, 2, 3, and 5 are generally used, so you can focus more on the facts with 6, 7, 8, and 9 if you need some practice.
This rewarding game will help you practice multiplication, division, and factoring. Knowing the factors will help you identify the “Greatest Common Factor” (you write all the factors of each number then choose the greatest number that is common to both lists). Practice by playing!

Rounding Numbers (Unit 0.3)
The key idea is to move the number to the closest allowed number. For example, when rounding 584 to the nearest ten 580 is closer to 584 than 590, so we round to 580. If you needed to round 584 to the nearest hundred, then 600 is closer than 500.
This video has hysterical birds that flap but do not move. And it emphasizes this rounding idea using the term “midpoint”.
This Khan Academy video covers this ground well too. (#youcanlearnanything)
When you estimate with numbers, round them first then solve the problem. This will quickly give you an answer near the exact answer.

Problem Solving
These word-problem sequences give you immediate right/wrong feedback, and we will give you strategy feedback via email within 24 hours.
If it feels like you need more practice with these types of questions, we have hundreds of questions to support you. Let’s start with these questions to see where we are.
Basic Geometry for Problem Solving
You will see some questions about solving for the area and perimeter of shapes. Area is the space a shape covers. Perimeter is the distance around. This short video explains this difference in an example.
