A quick way to estimate the difference of two numbers is to round each
number and then subtract the rounded numbers. {See this previous post for help on teaching rounding!} More often than naught, this won't be the exact answer but it may be
close enough for many purposes.
If you are teaching Estimate Differences, I've got some great
lessons, tips, resources and freebies for YOU!
Students need this mental math not only for future math classes and
math procedures, but it is also an excellent life skill. Do you have
enough money for all your groceries? Did the cashier give you the right
amount of change back? When you relate math to MONEY, even eight year
old ears perk up! Problem solving extends to all aspects of their
world.
Once your students have a strong foundation of rounding, you can move on
to estimating the difference. Estimation is a powerful mathematical mental
tool to be used both in solving problems and in checking the answer to see
if it is reasonable.
Tips to introduce your lesson...
How to estimate differences by rounding:
How to estimate differences by rounding:
- Round each number in the problem.
- Subtract the rounded numbers together, mental math is even better.
- Check to see if you have about enough money to pay for your meal at restaurant before you order. Lobster or hamburger?
- Get a ball park idea to double check your answer to a problem. Is 300 an intelligent answer for 992 - 682?
Just for you, my Bloggie-Teacher-Friends, I've created 5 problems that
you can use to teach and/or review "Estimate Differences" with your class.
You can highlight them and print them or project them on your board, white
board, or smart board to complete as a whole class or
independent seat work.
Estimate the Difference by Rounding
1. Heather's Cupcake Shop sold a total of 624 cupcakes today, 391 of
those did not have sprinkles. How many cupcakes were sold with
sprinkles?
{Why is this important? Heather needs to know approximately how
many cupcakes to make tomorrow with and without sprinkles and how many
containers of sprinkles to buy each week.}
2. There are 621 apples in the store, 494 apples were sold by the end of
the day. How many apples were left to be available for sale
tomorrow?
{Why is this important? If the store sells close to 500
apples a day, they need to know approximately how many apple buy and
stock tomorrow NOT INCLUDING the amount of apples still at the store and
are available to sale. Too many apples and they might rot, too few
apples and the store doesn't make as much money as possible.}
3. Andrew's school sold 887 chocolate bars for a school fundraiser. If he
won the award for the most chocolate bars sold at 398 bars, how many
chocolate bars did the rest of the school sell?
4. Billie is reading a book that has 322 pages and she has already read
99 pages, how many pages does she have left to read?
5. Aniyah's Paint Company used a total of 775 gallons of pink and blue
paint this year. If 511 gallons of blue paint were used, how many gallons
of pink paint were used?
Answers
1. 200 cupcakes
2. 100 apples
3. 500 chocolate bars
4. 200 pages
5. 300 gallons
Once you're done with your lesson, I have a variety of resources to

Estimate Differences
Finding class time for your students to review the math skills you
have taught them can be very challenging. This bundle has so many
items for your small group time, math center time, homework, and
seatwork, that you will LOVE it and use it year after year!
My students LOVED having Color By Numbers, Center Games and Task
Cards at our Math Centers and your students will too! You can
dedicate one of your math centers (math workstations) as a math
skill only math center. By changing out the skill each day, each
week, or each month, your students already know the directions for
using that math center. Your math center can be placed in a folder
with the included folder cover (See my PREVIEW PICTURES) and the
student can take the center back to their seat if classroom space
is limited. Your students will enjoy the freedom of center games
and task cards while learning and reviewing important skills at
the same time! This 3rd Grade Math Estimate Differences Center Games, Color By Number, and Task
Cards Bundle is also perfect for assessment grades for 3rd Grade!
These Estimate Differences Center Games, Color By Number, and
Task Cards Bundle also include the answer keys. You can laminate the answer keys
for the task cards and leave at the center to allow it to be
student led, self-checking sheets. In small group lessons, you can
give each student three to four task cards and they can help each
other and review the Estimate Differences Skill by checking the answers that their partner or neighbor answered,
keeping everyone involved! Keep your students engaged, alert and
on their toes with this one little, cute Estimate Differences Resource!
Place the Color By Number Answer Keys at your center for a Student
Self-Checking Sheet too! OR place it in a folder in a different
location that they may go check once they show you, or a classroom
helper, the completed worksheet.

Thank you, Fern :) There are many ways to use this Estimate Differences Math Center Games Resource, here are a few of my favorite ways:
- Use one page as a game board, cut the other page. Place all those cards face down. Have the students turn over one card at a time, solve and place face up on the board. If they are incorrect, the card returns to the bottom of the pile. The winner is the student who places the final card. OR, for a "no winner" version, the goal is for the students to solve the cards independently, but to completely cover the board together. This version can ALSO be played two ways. One way is with the answer page as the game board, another way is with the math problem page as the game board instead.
- You can also play this game with cutting all the cards and matching up the problems with the solutions.
- For movement, place the problem cards around the room and the student(s) have to solve the math problem and leave the correct answer card at that location. Have a second student check the answers to extend the game.
- Mix all the cards together, with two students, deal 5 cards to each student and then place the remaining cards face down. Use as a Go Fish card game!
- Lay all the cards upside down on the floor and use as a Concentration (some call it Memory) Game!
Monday - Use pages 6 & 7, printed back to back, as an Estimate Differences pre-assessment. Plan your small groups for the week around the data from this and your other observations.
